Last May, I built my dream touring/century bike on a Cross Check frame. Due to problems with my road and commuter bikes, most of my 4000 miles since then have been on that bike. I built it from the frame up with my LBS handling the headset and wheel build. Here are the high points....
- SRAM Rival drivetrain in WiFLi configuration (12-32).
- AVID Shorty 4 brakes
- Velocity Deep V rims with DT Swiss hubs and spokes
- Ritchey seatpost, stem, handlebar
- Tubs Vega & Tara racks
- Ortlieb Front and Back rollers, plus Ultimate 5.
I've done a few S24O trips on it and it performs well. (I had an issue with a B.O.B. trailer that ended up in a broken derailleur, but that had nothing to do with the bike. That was operator error; inexperience with the handling characteristics of the B.O.B.)
The frame itself is very comfortable. My road bike is aluminum with 23mm tires and I experience contact point numbness above 60-70 miles. This steel frame with 28mm tires is much less harsh and I get no numbness up to century distances. The only tradeoff is a bit of bounce in dips, but I'll take that.
The only thing I've been dissapointed in has been the brakes, but once I replaced the factory pads with Kool Stop pads my dissapointment has eased. (My commuter bike has hydraulic disc and if there was an option to combine hydraulic disc with brifters, I'd rethink.)
If you're asking about the suitability of the frame, you should have no worry. I think the CC and LHT frames differ only by geometry. If you asking about the factory build out, that's more personal. It seems to have a slightly lower gearing than I've got currently, but most people would not consider that adequate and would look for a triple. If I ever face a tour with serious climbs, I'll probably switch out the drivetrain.
I have no experience with the Trek so I cannot speak to that.
