The Wilier 503X Pro is the completely new design of the flagship among the aluminium hardtails. The developers at Wilier have rethought the details and tested the 503X Pro on the best MTB tracks in the Dolomites. It meets the needs of a broad mountain bike audience and brings more people into the terrain and into the mountains. The double-butted 6061 aluminium frame incorporates the latest advances in off-road biking.
Boost rear frame
The width of the rear hub was brought to 148 mm, the boost standard. This increased space allows for optimal clearance even with wider tyres (2.3"). The wider and slightly shortened rear hub ensures an increase in the bike's manoeuvrability.
