This model can be positively referred to as the 101XN’s little brother, boasting the same features and identical geometry, as well as an asymmetric rear triangle styled after the Cento1 SR, oversize bottom bracket, and internal cable routing. The major difference is that the Wilier 501XN 29er Carbon Mountain Bike uses a slightly different carbon composition than the 101XN.
