SRAM XX1 X-Sync Chain Ring
Details
Le plateau de chaîne XX1 X-Sync de SRAM s'adapte parfaitement à la manivelle XX1 de SRAM. Il présente un profil de dent large-étroit-large pour maintenir la chaîne en toute sécurité sur les terrains les plus accidentés, aucun guide-chaîne n'est nécessaire. Une variété de tailles allant du spin-to-win 28T au hard-man humbling 38T vous permet de composer votre équipement pour vos forces ou votre terrain. La conception unique du plateau vous permet de faire glisser la glissière sur le bras de manivelle, de sorte que le retrait de la manivelle n'est pas nécessaire.
SRAM's X-Sync technology ensures a perfect fit between the XX1 chainring and XX1-specific chain for unheard of chain stability with no slap, no drops and no chainguide or weight penalty!
To choose the correct chainring, 1) determine the number of teeth (they're usually marked, or simply count them), 2) determine how many bolt holes there are (usually 4 or 5), and 3) determine the Bolt Circle Diameter (BCD; see diagram).
Common BCDs include:
130mm (Shimano Road)
135mm (Campagnolo Road)
110mm (Compact Road)
and
104mm, 94mm, and 64mm (Mountain)
Finding the number of teeth and bolts holes is easy. If you don't know your chainring's BCD, measuring it is tricky. So, instead, measure the exact distance (center to center) between 2 adjacent bolt holes. Then find that number on the correct chart below to determine the BCD for your chainring.

| 55.4mm | 94mm |
| 64.7mm | 110mm |
| 76.4mm | 130mm |
| 79.5mm | 135mm |
| 84.6mm | 144mm |
| BCD Chart for 4-bolt Chainring | |
| Bolt to Bolt (measure center to center) | Bolt Circle Diameter (BCD) |

| 45.3mm | 64mm |
| 48.1mm | 68mm |
| 73.6mm | 104mm |
