hi. i just bought a rear wheel for this bike. the hub on the wheel is 145mm but the shop assures me they can shorten that for a fee. i would presume that my rear hub spacing is 135mm but cannot find these specs anywhere to confirm. i am also not near the bicycle so i cannot measure.

does anyone know if the rear space for the hub is 135mm? what about the space for the front hub?

thanks

You bought a rear wheel intended for a tandem. I'd definitely return it and get a correct one if at all possible. Modifying it to 135 mm (see below) would require shortening the axle and redishing the wheel so the shop will charge you accordingly

Trek's web site "Bike Archive" listing for the 2006 Navigator 200 doesn't specify the rear spacing directly but the hub is listed as a Shimano "RM60" which is an MTB hub and, thefore, 135 mm. Also, the Shimano's tech document for that hub specifies a 146 mm rear axle which confirms it's 135 mm OLD.

All standard road and MTB front hubs are 100 mm OLD.

THe Clydesdale forum has a fairly steady discussion about wheels stong enough for heavy guys, and rarely is the consensus that a tandem wheel is necessary. 99% of the time, wheel failure is caused by having the wheel improperly tensioned from the factory.

There are two things that make tandem wheels stronger - more spokes and less dish due to the wider hub. If the hub is narrowed you will lose one of these advantages, and possibly make it worse than it would be if it were a hub designed for a 135mm spaced frame.

My advice to you: return the wheel and get a 36 spoke wheel with an XT hub properly built, tensioned, and stress relieved.

And go over to the Clydesdale forum if you need confirmation of this or any other advice pertaining to big riders.
