Some questions for the experts. I hope you all understand my questions (some technical words are hard to find a translation for):
1.) I just bought a cheap Kinesis alu frame and fork, originally designed for a randonneur bike. I want to build a cyclocross bike with it but noticed that, compared to my roadbike, the wheelbase is much longer, including a more "lazy" Kinesis alu front fork (the "angle" of the headset tube, don't know the english word, and the fork stays).
Is this normal for a cross bike, or should it have angles and a wheelbase comparable to a roadbike?
2.) In the rear I have a short cage Shimano Ultegra and a 12-25t. cassette, but what to do in front? A single blade setup (Holland is flat enough) and I'm considering two options:
A.) Shimano Ultegra cranks with 42t chainring, Spooky chainguards and an Ultegra 118.5mm bottom bracket
B.) Shimano XT cranks with 44t chainring and a Roox Chaindog (or alternative a Rohlof CC8290 Kettenführung)
Which opinion would be best? It appears to me that I save weight with option B but does is work as good as option A? Also, does anyone know which bottom bracket length I should use for option B in order to get a good working chainline?
3.) I've got my old set of Spinergy Rev-X roadwheels. Can I use them for cyclocross?
Thanks in advance,
Timo
