Cotton shirts become waterlogged. You will be happier with something that does not. There are many excellent garments that people can recommend from experience. My system works very well and consists of not made for bicycle gear. A long sleeved, high-neck silk jersey is very comfortable. It is cool in hot weather and warm in cool weather. Carries sweat away from the skin and evaporates it. The jersey is never clammy, and on down-hills dries immediately and insulates me. When weather is cold enough I put over the silk jersey a long sleeved high-neck wool jersey. Add a wind breaker when the weather is even less temperate. A bicycle wind-breaker should be a form fit so that it does not flap and pump away the warm air layer beneath it. Thanks for the tip. As it happens, I do have a long sleeved silk tee type shirt which I use as an undergarment for motorcycle riding. I think it'll work well for my bike riding - I just never considered it. If others wish to get something like, this, I found it at Cabelas for surprisingly little money. Apparently hunters use such items. |

Now this is a great point and shows how ignorant I am here. I noticed that my bike's seat is only slightly higher than the bars, but I figured that was my manner of adjusting the whole thing compared to modern manners of adjusting. Also not being experienced, I figured they very high seat / low bar combo was right as it was adjusted by pros at the LBS. I'm out of seatpost which is why I left mine as is. I thought *I* was wrong, but I see now due to your post that this is a preference thing. Seat height is determined by your leg length, not handlebar height. The seat usually ends up being higher than your handlebars, because leaning forward is more efficient than sitting up. It is also better to reduce fatigue if you take long rides. However, some people prefer to sit up more, especially women. If you're out of seatpost, you can get a longer seatpost, but a larger bike might be necessary to get a proper fit. I definitely do not wish to look the poseur because I can't back that play. This may cause a laugh from some here, but I wear a tee shirt instead of a real bike shirt because I don't want to pretend to be what I'm not. Wear what you want, not to be a snob or a reverse snob, either. If you discover the advantages of cycling clothing, then wear it, not because you're a super cyclist but because you like to wear it. And if you don't like it, that's fine, too. I often wear street clothes when I ride, even on long rides. I also ended up with the seat a bit nose up - something the owner of the bike questioned, but after messing around with it for a while, I find this works for me. The classic racing position is with the nose very, very slightly up. Or totally level. If it points down, it might mean the seat is too high for you, and I doubt it is. OK, it's easy to make fun of me here being a stark new guy, but also I find it very difficult to believe that experts spend all this money on wheels to no benefit. Apparently, based on my buddy's talk, the one who sold the Giordana to him put some junk wheels on the bike to sell it as a bike rather than a pile of miscellany parts. Believe it. We are all governed by our emotions to varying degrees, whether we admit it or not. And we sometimes express our love for our sport by spending money, and we justify it irrationally. Wheels need to be durable, and they need to be as light as you can afford them. Light wheels are nice, but I don't think it's necessary to spend truckloads of money on wheels. And the recent trends are to sell light wheels that are not designed to be durable. A fool and his money are easily parted. A lot of people clamor at the opportunity to spend money, thinking that if it costs more, it must be better. That said, I'm unclear on exactly what is wrong with these wheels aside from perhaps the hubs. If I spin the wheels with the bike in the air, the wheels stop spinning sooner than a similar spin on my daughters Cross bike. That could be bad bearings or less of a flywheel effect. Bearing friction plays no practical role in how your bike rides. The critical thing is rolling resistance that your tires cause. Get light, supple tires that accept high pressure, and pump them to 90 or 100 psi. I have the shoes as I needed pedals for this bike so got some almost worn out SPD pedals and shoes to match. I needed the pedals that came with this bike for my daughter's bike. I didn't know any bikes had fenders any more except for those bikes which look like they come from the 30's. Clipless pedals sure are nice, aren't they? Fenders are actually nice, and it's a very well kept secret in the US. Yes, you have to pay to get them, since no one wants to buy a bike with them. But lots of road bikes don't have the eyelets or the clearance to fit them. -- Tom Reingold Noo Joizy This email address works, but only for a short time. |

Maybe I'm dopey here, but I figure the wheel is the main part & limiter of a bike like a speaker system is for a hi fi. No matter how good the bike, crummy wheels make for a crummy bike experience. I figured you put in your big money in a wheelset for a bike like you put your big money in speakers for a hi fi. So I"m wrong? You're not dopey. Stop selling yourself short. The component that matters the most is the tires. After that, it's the frame. Wheels matter only in weight and durability, which, of course, are at odds with each other, so you have to make a compromise. -- Tom Reingold Noo Joizy This email address works, but only for a short time. |

If you have to buy a new set of wheels, then I'm not sure its that great of a deal. Cheap wheelsets that will function well enough can be had mail order from Nashbar or other mail order places. Maybe a local shop has some wheels taken off another bike they can sell cheap. Cheap being the key word here. Assuming the borrowed bike is a freewheel bike, you should be able to find these wheelsets really cheap. At the very most a new set of freewheel type wheels should cost $100. Or less. The wheels roll for sure. I figured if I could buy this bike cheap, and have a $1,000 budget for a new bike if I made that decision, then I have money left over to buy a good wheelset. The owner said the wheels aren't nearly up to the quality of the rest of the bike. Given that the drive train / brakes are Dura Ace, which I've learned is the top of the line, I figured to get the entire bike equal which means a more expensive wheelset - although I can't tell you what you buy with more outlay. But I also can't tell you why Dura Ace is so good. Use the wheels until they self destruct. As long as the poor quality wheels you currently have are true and the bearings are not binding, you will never know they are poor quality. Now if for some reason they do not stay true and break spokes, then replace the wheels. Until then, don't waste money on new wheels. I figured you put your big bucks where the interfaces are so the road interface is the wheels. I also figured the guy who sold the bike to my buddy took off great wheels which is why the ones on it aren't any good. They are true (I trued them). I don't know what makes them bad. The most important interfaces on a bicycle are where the rider and the bike meet. Saddle. Handlebars/brake levers/shifters. And pedals. And having low enough gears to comfortably get up any hills you happen to be climbing. Very important. The crankset I mentioned comes with 50-34 tooth rings on it. It costs more money to replace chainrings. Money that could be used to buy a new bike if you start replacing parts on replacement parts before you even use them. The 50 will work for most riding around. The 34 will work very well for any hills. I think I'll start with a cogset and see how that works. I am ok putting on parts which I can take off if I can't buy this bike or I choose not to, but I guess a crank is specific for a bike or I'll buy my new bike around a crank which I think is silly. From what you wrote in other posts about being in hilly/mountainous country and struggling on some hills, changing the cogset to a 28 tooth large rear cog will not be enough. Assuming your race oriented bike currently has a 23 tooth big rear cog on the freewheel, going to a new freewheel with a 28 tooth big rear cog will get you roughly one lower gear. Not a huge amount if you are really struggling now. You can cheaply replace the smaller chainring on the crankset with a 38 or 39 tooth chainring. Nashbar has them for 130 mm bolt circle diameter cranks (Dura Ace). $12.95. Easy to change. Maybe, maybe, maybe changing the rear freewheel to 28 tooth and the front chainring to 39 will get you a low enough gear to be happy with for awhile. http://www.nashbar.com/profile.cfm?c...eid=&pagename= The reason for my previous mention of the compact double crankset is it will get you fairly low gears without having to change anything else on the bike. And it can be moved to another bike easily. You can get a very nice road bicycle for $1000. Look for sales at bike shops or mail order. Its best to know what size you need if ordering mail order. Probably crucial to know your correct size. That you get from riding and figuring it out. http://www.gvhbikes.com/welcome.html I had dealings with the original Gary V Hobbs. Guessing the new owner is carrying on the good customer service. I think given my newness at this point, I'd only buy mail order very cheaply or from a trusted source. I think I'm an obvious candidate for the LBS to make a sale. The parts mentioned above are cheap and functional and easy for you to install. Might have to have the local bike shop change the freewheel out. Cone wrenches to fit the hubs. Use a vernier caliper to figure out the size of the inner ones. 13/14 and 15/16 and 17 should cover most things. Traditional crank puller for square taper cranksets. Assuming that is what is on the bike now. If you get a new crank/bottom bracket then you will have to get a new crank puller for the new crank (ISIS or Octalink specific). Bottom bracket hook tool for the locking ring. Assuming that is the kind of bottom bracket you have now. New style for a new bottom bracket. Pin spanner to adjust the old bottom bracket. Headset wrench 32 mm. Freewheel removal tool. Assume Suntour style with 4 notches. Chain whip. Crescent wrench and metric wrenches and metric Allen wrenches are also needed but I assume you have these already. OK, thanks very much for that list. It seems affordable. I do have all manner of conventional tools for working on my motorcycles. In fact, I have a full on shop. What does a chain whip do? The only thing I know about that I'd call a chain whip is a pipe wrench sort of affair. Look at mail order places and the Park Tools website to see examples of the various tools I mentioned. Chain whip is needed to get a freewheel or cassette (rear cogset) off a bike. And you need a chain tool. But if you have mountain bikes you probably already have this. Cheap dual pivot brakes can be head from Nashbar that will work fine. Lots of power and easy to squeeze. Cheap too. I never thought of that. I'll check. http://www.nashbar.com/profile.cfm?c...eid=&pagename= If you knew what you were doing you could probably replace a few parts and get by cheap. But if you have to replace quite a few parts the owner takes for himself and then pay for what is left and then replace a few more to make it satisfactory for you to ride, .... You might be close to half or more of the cost of a new bike. If I knew what I was doing, I'd be giving instead of soliciting advice here. I've probably learned more from this thread about bike mechanicals than I have in my few months of road riding including reading many magazines. I don't mind putting in some parts that the owner takes with him if we don't come to a bargain. After all, I AM getting use from this bike so some rental in the form of my improving it is not only reasonable, but something I'd like to do. After all, I'm wearing out HIS machine. -paul The parts I mentioned can be taken off by you and the old ones put back on. No need to lose the parts if you don't end up with the bike. Here is my final recommendation to you. 1. New 39 tooth chainring for the crankset for $12.95 from Nashbar. Easy to put on yourself. No other bike modifications needed. Gets lower gears. 2. New 6 speed freewheel from Nashbar for $19.95. 14-28 tooth model. Assume your bike currently has 6 speed freewheel and the downtube shifters will work with the new one. I'm fairly confident in this assumption. Pay the bike shop to change freewheels for you. Cost you $5. Gets you lower gears. 3. New chain from Nashbar. Cheap 6/7 speed chain. $10. Needed because you have a bigger cog in back and the chain must be able to wrap around the big ring on the crankset and the big cog on the freewheel to be safe. 4. Dual pivot brakes from Nashbar. $29.95. Short reach model most likely. Easier to operate than the ones you currently have. 5. New brake cables. $5 total for both sets. Get them from Wal-Mart. Or Nashbar. $90 total roughly. Probably low enough gears. Everything is easy to put on. Except the freewheel which you can have the bike shop or the bike owner do. |

Of course they are. But at least it's telling poseurs that having fenders won't make them less cool. FWIW, I have black SKSes. The stays blend in with the spokes and the fender blends in with the tire. From a distance, you wouldn't even notice them. Unless you're riding behind me on a rainy day. And I live in Seattle. -HW |

I think he has a point which is relevant to me because, as a weightlifter, I have a large chest (compared to civilians) making it tough for me to get in a full crouch. Part of the reason I can sit my bike (as 41 pointed out) indefinitely is the relative positions of bars and saddle which I'd lose in a new 'poseur' bike. I'd not gain speed if I were uncomfortable. I definitely do not wish to look the poseur because I can't back that play. This may cause a laugh from some here, but I wear a tee shirt instead of a real bike shirt because I don't want to pretend to be what I'm not.

It's just me. I don't want to pretend to be what I'm not. The classic racing position is with the nose very, very slightly up. Or totally level. If it points down, it might mean the seat is too high for you, and I doubt it is. You can see it is nose up if you look but it's not dramatic. I got there by trial and error as suggested by a fellow I met who was an expert. It really makes a terrific difference to the good. I need to mention that I've broken each limb at least once, have a rebuilt knee, have a thrice broken shoulder - and that's just the start of my list. So my anatomy may be very different from standard. Believe it. We are all governed by our emotions to varying degrees, whether we admit it or not. And we sometimes express our love for our sport by spending money, and we justify it irrationally. Wheels need to be durable, and they need to be as light as you can afford them.

A fool and his money are easily parted. A lot of people clamor at the opportunity to spend money, thinking that if it costs more, it must be better. As I posted elsewhere, all athletic endeavor is governed by your mentals. I learned this as a distance runner. I understand this is a prime element of tennis playing. It extends to all physical activities. Clearly, IMO, if you feel your wheels give you an edge, you WILL have an edge. I may buy some super lightweight ones (I almost did yesterday but was unsure if a wheel for an 8-10 speed Shimano would work with my 7 speed setup) just for the heck of it. Now that I have decided to keep the Giordana, I have some budget I can apply to it. I spoke to my buddy's wife and I feel sure I can buy the bike. Bearing friction plays no practical role in how your bike rides. The critical thing is rolling resistance that your tires cause. Get light, supple tires that accept high pressure, and pump them to 90 or 100 psi. I did. They are so supple that I thought they can't work as I can fold them up & put in pocket. Clipless pedals sure are nice, aren't they? Yes. I watched the Tour. One of the pro talkers said the guys there pedaled in 'circles' so I'm trying to spin the bike in imitation of the experts. It tires me too much to do always, but I'm extending my range. I think this will pay off and I could not do it w/o the clipless. I did a tip over on my first outing which scared the whiz out of my daughter, but it takes a LOT more than a tip over to hurt me. -paul |

That's not so important. If you don't have low gears, you have a better chance of learning to climb hills well. The super low gears that bikes come with these days helps to ensure that riders never learn. And if you don't use the opportunity to learn, that's OK, too. You can walk up hills. Is that so bad? My approach to difficult hills is to stop and rest when it gets really hard. Then I resume on the bicycle. I don't like to walk. But it's fine for some people. I'm in no danger of having too low gears. My lowest ratio is 2:1 (45:22). How does that help me learn to ride hills? I was hoping for an easier low gear if I can find (and my machine handle) as much as a 32 for my largest cogset sprocket. I have plenty of high left as my large chainring is a 52. I seem to be the only two speed bike out there. All others have a very small 3rd chainring which looks like a 35 or less. I was riding my motorcycle today on a dirt road up a steep hill when I stopped to chat with a bicycle guy who decided to rest and then resume. Did we meet? -paul |
