Trek Madone Review

[wpcol_1third id=””class=””style””]

Want to know more? Ok; let’s start at the back. Attached using integrated threads in the frame, the caliper sits under the bottom bracket and, in essence, is a conventional dual pivot design reversed so the cable runs to the right as the caliper is viewed head-on.

This inversion is needed to keep the inner wire’s clamp away from the chainset, where access for maintenance would be severely impeded.

As it is, getting at the brake block shoes requires either a suitably versatile stand or that the bike be inverted. We’ll find out whether this is worth worrying about at the same time we find out whether the blocks wear more quickly placed low down.

The same goes for worries about the perceived difficulty of keeping the rear caliper clean; given that one placed conventionally gets a hammering by muck thrown from the back tyre, it may turn out to be a non-issue for the purposes of comparison.

For most riders, brake performance, not ease of scrubbing, will be the deciding factor. Fear not; performance and control are right up there with the top-level offerings from the major component manufacturers. Well, with their conventional dual-pivots, at any rate.

The aero Madone fork bears three threaded inserts, which between them allow Trek to fit either the standard-issue Bontrager dual-pivot caliper, using the middle and right-hand inserts, or Shimano’s new Dura-Ace design with its new “symmetrical” design, which requires the use of the two side inserts.

Claimed to offer some 20percent greater braking power, Shimano’s caliper may well exceed the Bontrager front’s performance.
