I was in a similar situation last year and built up an on/off road bike with a used frame and some parts I had laying around after upgrading some parts on my road frame. I'm curious what people think:
Frame: Lemond Proprad (True Temper Plat OX tubing, rack mounts, canti brakes–would love disk but I wanted to be able to interchange wheels with my other bikes)
Groupset: SRAM Franken-Force (ie, lots of various SRAM parts that equate to being different years of Force/Red…I don't like their chains though)
Bars: KESTREL EMS PRO SL CARBON (180g and makes the WW in me proud but the husband who wants to stay alive will be putting on an alloy bar if I were to go on some kind of
Wheels: Neuvation R29s (alloy, 20/24 spoked)
Tires: Schwalbe CX Comp (700×38 cyclocross tires) w/ self sealing tubes that I hate
Gearing is a compact up front (36/50) with a very wide cassette in back (11-32).
I haven't really had many issues with not having enough gear ratio to make it up steep inclines but I rarely see >5% since I"m in the midwest. I'm wondering how you guys think it would do on a trip like the Continental Divide? Mainly, I'm a roadie but I wanted something that can handle single track but I've been slowly turning into a bike-packer over the past few years.
The tubing is pretty thin, but strong. My main concern is that if the frame cracked I'd be done because a random welder would have trouble getting it repaired. For my current needs, having a 17lb bike trumped having one that's bombproof.
