|I finally got around to upgrading the components on my 2001 Major Jake. I'm a Campy guy so I went with Centaur 9. I love the feel of the ride, and I think I have a truly great bike now [with one reservation... see my post in the BB spindle length thread]. The old components -- 105 and Tiagra were not wasted. My GF got herself a 2000 Jake frame on closeout and I built it up for her. We're going to get muddy together! This is what the erstwhile Major -- now a General or at least a Brigadier -- looks like.|

|What is the weight? I am looking to shave a some weight on my colnago, some how it weights 19-20 lbs. Might be the wheelset; campy moskva, they are not light. |
Otherwise I did not see, but does the jake have a top pull front derailuer? and if so what are you using? I have seen a good deal of top pull frames set up with campy, with a single chain ring. By the way I have a sachs top pull on the colnago, minus that the drive train is a mix of chorus 8 levers and a daytona 9 derailuer; chorus/ moskva wheelset; raceface prodigy cranks, thinking of swaping for chorus cranks.

|I haven't weiged it, but I'd say it's in the 20-lb range. It's just a bit heavier than my road bike [steel Marinoni], which weighs in at 18.5 lbs without pedals, so I'd say it's probably between 19.5 and 20 lbs.
The frame is Easton Ultralite, the wheels are Open Pros with Daytona hubs and DB spokes. The fork is the Kona Project 2, which is a damned heavy piece of steel. I could lose a pound with a lighter fork, and I might do that, eventually, but I'm in no rish right now.
The FD is bottom pull. Not much to be done there, and as much as I think this might cause problems in the mud, I'm not going to sweat it too much. I really like the frame, but it has a few maddening shortcomings:
1. Downtube, bottom-pull, routed shift cables.
2. Below-the-downtube split cable stops like on a MTB. This is a BIG problem for setting up a FD cable tension adjuster. I rigged a small barrel adjuster, but we'll see if that actually works.
3. Very big, fat and beefy chainstays. Kona is a MTB company and this frame is a MTB designer's idea of a cross frame. The fat chainstays don't leave a lot of clearance for the small chainring. I'm considering investing in the 115 mm spindle BB meant for triples so I can get an extra 4 mm clearance for the small chainring. I wonder if this would cause any shifting problems...
I might have missed something, but why would you want a FD at all, even a top-pull one, with a single chain ring?
[BTW, your righ sounds very cool...]

|I think I was trying to say that I have seen a number of frames with top pull mounts but set up with a single chain ring, reason being that top pull derailuers might be hard to come by.... I really dont know.|

|most race cx bikes are set with top pull as most mfr's avoid running cables on the downtube to avoid gunkification. Most race bikes have all cables (Rear Brake, Fr. and rear der.) running across the top of the top tube (to avoid contact during portage) so I don't think lack of top pull der.is the problem. A lot of racers just avoid multiple chainrings and are riding such bikes.|| |
