The 503X is the complete redesign of our flagship aluminium hardtail. We rethought the details, and tested the bike on the best MTB trails in the Dolomites. The 503X meets the needs of a wide mountain bike audience, getting more people off-road and into the mountains.
The 6061 double butted aluminum frame incorporates the latest advances in the offroad field:
- Tapered Head tube: 1 ½" bottom, 1 ⅛" top
- Integrated cables
- Press fit bottom bracket 92 mm
- Seatpost 27.2 mm diameter
- Direct mount Derailleur
- Thru-axle rear dropout: 142 x 12mm
The 503X is available with 29" wheels in 4 sizes: S, M, L, and XL.
