Short-reach brakes. JT I should've been more clear: the bike I referred to was equipped with 28c tires at the time but can accept 32c size rubber with fenders and larger sizes without - I suppose a contemporary equivalent would be a Rivendell Rambouillet. And I also owned an Asian made Bianchi racer from the late 80s that accommodated 32c tires (without fenders). Calipers notwithstanding, essentially these 'road bikes' were what today pass for CX bikes, that is, drop bar bikes that afford a wider choice of rubber. (Put drop bars on an average modern hybrid and the same could be said of it.) Their versatility was an asset, particularly as it did not detract in any way from performance. Luke |

The bikes don't get much use, admittedly, but fenders don't make a difference here. There are essentially two kinds of drop bar bikes: Racing bikes (be just like Lance), where everything is based on weight reduction, and yeah, racing teams would likely get a custom built seatpost, and pay $500 for it, if it reduced the weight even 5g to give their racer as much advantage as possible. They certainly would not "waste" 200g per wheel for fenders. Road bikes, ever head out, on a nice sunny day, not a cloud in the sky, nothing forecast except sun, and then get a torrential 2 minute downpour, and end up with the "skunk stripe" as the only proof, because it got sunny again afterwards? The real issue here, is that frame designers leave the 2.5mm wheel clearence dictated from racing bikes, which means no chance of stuffing a fender in there. If they left say 5cm, and added the frame mountings, it wouldn't make any real differance weight wise, and people could add their own fenders. Then again, you might have so many people add after market fenders, that a whole new style of road bike would be born, the fendered road bike, and bike assemblers would start adding them as standard equipment. A rear only option, would be to add a rack, the rack could have a solid piece over the top, which would remove the skunk stripe and wet behind, effectively making a rear fender, debating doing this with my MTB......

Tires of 28-32 mm width provide better ride comfort, handling, and traction, and offer greater versatility on what surfaces can be ridden on. And unless the bike is for fair weather only, fenders are an excellent addition. Again, the extra weight and drag of fender should only be of concern to racers. They should have 36 spokes too of course. Unless they are racers of course. Right? This is RBT right? So you really shouldn't forget to add that. And of course most people's top gear is too high. Don't forget that. Agreed. The weight savings and decreased aerodynamic drag from less than 36 spokes is trivial, unless one is racing at a level where a couple of seconds difference in elapsed time will affect placement. Otherwise, lower spokes counts are a silly fashion statement, trading looks for decreased reliability/longevity. If professional riders that are putting out average power in the range of 400 watts when riding hard use 53/39 chainrings and 11-23 clusters, then this gearing is obviously way too high for an average road bike rider with less than half the power. From a cost/use/practicality standpoint, what most road bike riders should be riding are steel frame bikes with adequate frame clearances for wider tires and fenders, 36-spoke wheels with aluminium alloy rims (with sockets, but no anodizing), smooth tread clincher tires, 8-speed freehub/cassette and bar-end shifters. -- Tom Sherman - Fox River Valley (For a bit) |

Dumpster diving veterans can attest that a resurrected vintage road bike (circa 80s) often equals in versatility a typical CX bike of today - both can accommodate a variety of tire sizes and peripheral equipment (racks and fenders). Older "sports tourer" frames are versatile in that they can take some pretty fat tires. I use 35mm studded knobby tires on one of my bikes in the winter. When forks and chainstays were brought closer together, and chainstays were shortened in the recent fashion, I think usefulness was lost and nothing substantial was gained. |

They certainly would not "waste" 200g per wheel for fenders. You may not have been paying much attention to racing in the last 4-5 years. There is a weight minimum, and pretty much anyone can be riding an illegal (sub-weight) bike in the PRO peleton, not to mention the many elite and not-so-elite racers. So there really is not any target of 5 grams, not 50 grams, and depending on who is riding what, 500 or more grams. The weight battle is over, unless UCI changes the minima.

It's water and dirt, and it doesn't happen all that often. I must be among the privileged, having a washing machine. The way you write, it rains on your parade all the time. Aside from Seattle, I have not heard of too many other reliably rainy cities. But I don't know, so you can tell me where they are. Then again, you might have so many people add after market fenders, that a whole new style of road bike would be born, the fendered road bike, and bike assemblers would start adding them as standard equipment. I have a Zefal fender on my winter bike. It jumps over the rear triangle and clips onto the seat tube. My delightful frame has exactly enough seat tube above the joint so that it goes there, and with the saddle, does a good job keeping me reasonably dry. On my good season bike, no fenders, and back to washing machine and showers for solutions. A rear only option, would be to add a rack, the rack could have a solid piece over the top, which would remove the skunk stripe and wet behind, effectively making a rear fender, debating doing this with my MTB...... Take a look at the Zefal - it may be the kind of answer you would accept. It clips on or off in seconds. -- Sandy The above is guaranteed 100% free of sarcasm, denigration, snotty remarks, indifference, platitudes, fuming demands that "you do the math", conceited visions of a better world on wheels according to [insert NAME here]. |

It is steel, apparently all else is wrong. I don't race, but one goal when upgrading was to lower weight. I have Easton CF bars and post, a Dura-Ace driveterain, although the 9-speed cassette [14-28] is mostly Ultegra and the crankset a triple 30/39/53. Of course the wheels are wrong, Peter built me a set of DA hubbed Velocity Aeroheads 28f and 32r. I don't purposely ride in bad weather, so no fenders, not that they would most likely fit. Part of why I love my bike, is its appearance, fenders are ugly. And when I have gotten wet, my concern was towards the bike, not me. The worst rainstorm I was caught in, my shoes got so wet they were squishy, fenders wouldn't have changed that. And God forbid, I have those evil STI brifters. The pedals are those impractical SPD-SL Look-alikes, with Sidi Genuis 4s, which make me waddle like a duck. Now, why do I have a bike like that, well because it inspires me. Just sitting there, it screams "RIDE ME". And I do. The bike has its Ritchey WCS stem in the upward position, bars are at most 2" lower than the saddle. The saddle is a Selle Italia Prolink Basic, not the lightest, but for me, quite comfy. Did I mention that I enjoy riding this bike? Now, maybe some of you, who are convinced that only racers can ride bikes with less than 36 spokes, no fenders, and brifters, can explain what compells me to be so wrong. Do I need to make ammends? Life is Good! Jeff |
