There are people on this NG who do not understand the difference between top speed and average speed. Well, to be fair, you've bragged endlessly about how fast you ride when that suits you, and you've switched to saying how slow you ride when that suits you. You seldom clarified whether you were talking about average or instantaneous speed, until people began calling you on the discrepancies in your posts. -- - Frank Krygowski |

No. All I wrote was that I routinely ride 20mph on trails and that's a fact. There are no discrepancies. Back then I brought that up because I expect the riding equipment to hold up under those conditions and some doesn't. And yes, I do take the liberty of riding 1mph at times when I want to. On singletrack watching animals or scenery. Or recently on a MUP to watch the massive release of water at Folsom Lake dam. For me bicycling is about freedom and that also means freedom from motor vehicle traffic whenever possible. Whether I ride at 20mph or 1mph nobody gets bothered by it. -- Regards, Joerg http://www.analogconsultants.com/ |

It is 7-speed, was 6-speed but I converted it after the last UG freehub went ka-crunch. You could fit a rack to the Ridley but I don't know of the reliability of the rear drop-out mounts. |

So you think of sprint speeds through stop lights as an average speed do you? I've noted many times that average speeds around here are 12 mph for a hilly ride to 14 mph for a flat ride. So higher speeds wouldn't be "averages" now would they? You certainly have a lot of memory problems for someone that is complaining about my memory problems. |

This is OK on an MTB with full suspension and a great deal more weight, but on a street or CX bike the bike will simply crash. I suppose you could ride with just your index finger on the brake but that loses you the control you need. My MTB has very fast reacting disc brakes. I generally ride with just the index and middle fingers over the brake handles. A good squeeze from two fingers can lock up the wheels. Yet I only locked them up when I wanted to. Like when I accidentally blew by a trail turn-off and was heading for a rock slide, and let the front and rear dig into the loose gravel. Rim brakes do not work well in mud and rain. The worst is the delay when the rim is soaked. Precious seconds go by and that could cause a crash. Almost has on my old MTB with rim brakes. The only time I almost went over the bar was when I test-rode the new MTB in the LBS parking lot. I didn't instantly remember that bicycle disc brakes could be this powerful and the rear wheel came off the pavement for a second. Ever since I rode a bicycle with disc brakes for the first time I never looked back. I put TRP 9.0 V-brakes on the Ridley and the difference in control is amazing. And despite what so many people say I've seen too many Titanium bikes crack at the welds in a pretty short time. My MTB buddy has a Ti-MTB from BikesDirect. It's been through nyumerous nasty crashes and ... not even a dent.

It would have to tolerate well in excess of 50lbs while going at a good clip on road like this: http://www.themirrornewspaper.com/wp.../AW_Noward.jpg -- Regards, Joerg http://www.analogconsultants.com/ |

The last time I went OTB it was with ordinary caliper brakes and because my son had crashed in front of me on a wet descent. Well you I don't remember the last time I ever had any sort of exceptional power with dual axle caliper brakes. Very much the opposite in fact. Mechanical disks are NOTHING like hydraulics that are properly set up. Does your Roubaix have one of those 7" disks? I would imagine that there is a great deal less danger from the power of a disk on roads compared to off-road. On steep off-road you take your hand off of the brakes and in 40 feet you can go from 8 mph to 30 mph only to hit more rough roads. On full suspension that isn't a problem but CX not only doesn't have suspension but is about the weight of a road bike. With low gearing it simply lifts the front wheel off of the ground on hard push up a steep uphill (20% or more). The hydraulic brakes are powerful and they do take some use to understand.. Front braking is not all that much different from a good dual pivot; however, rear braking is much more positive, and that is where you have to avoid ham-handedness. This takes about 90 seconds to figure out, and most rear wheel skids are controllable during the learning period. This isn't anything that isn't part of the game. Talking to the local shop mechanic he said that you can't use the bottom two gears usually and the trick is to use third (which is about the same as a low road bike triple gear 30-28) for climbing the steep part and then use the lower gears to go ultra-slow and rest when the trail flattens out a little. This really works well and my average over a hard trail went up a couple of MPH using this trick.. Both the cable and hydraulic brakes beat the hell out of calipers in rain and slop, like the snow slop I've been trying to ride in. In dry weather, any good rim brake will do the job. I don't see any reason for hydraulic discs on high-end race bikes that will never be ridden in the rain, except maybe to avoid over-heating CF rims -- which could be a real problem with tubulars, although I'm just speculating. Personally, I think its just marketing. I don't ride in rain though it is muddy off road a good deal. And I had no problems with V-brakes. |
