Correct, the Tequesta was a 26” mtb, with Shimano stx 3x7 & cantilevers. The center pull brakes have really been a non-issue, far simpler than I expected. Basically plug, adjust, play. Only real problem I ran into had to do with the wide chainstays and the relatively narrow q-factor of the FSA Gossamer Pro ABS BB386evo crankset. I needed to use the included spacers to keep the crank arms from hitting the chainstays, and even with the spacers I only have a couple mm of clearance. Because of this I had to ditch my pedal bolt mounted sensor magnet (too thick) and strap one onto the edge of the crank arm.
The original stem was 130x5 and I replaced it with a 120x10 as a total guess as to positioning and I think I was close but it may still be a little long, I feel a little too stretched out. But, I suppose if that’s all i have to change then no big deal.
