Trek has equipped its X-Caliber mountain bikes with a self-developed hub that is not available anywhere due to the special installation width of 141 mm combined with a dropout axle, but from now on it is available at Vlechtservice!

This hub is equipped with strong industrial bearings, so it guarantees long rides without worries.

This wheel is braided with the Andra 321 rim, which is recommended for heavier bikers from 90 kg.

We also have a variant with the Zac 421 rim, which looks very similar to the original Bontrager rim. See related articles below.

Rim tape included.
