| Shifter & derailleur routing, choose one | Your choice of many, including:
Shimano note: Di2 routing is not compatible with older Shimano parts kits including 815, 8000, and 9100 series. Upcharge may apply. |
| Brake housing routing, choose one | External: Zip tie guides for optimal performance, smooth front-end handling, ease of maintenance, low maintenance, and light weight. Compatible with hydraulic and cable-actuated disc brakes. Available with internal brake routing upgrade for an upcharge. |
| Derailleur hanger | Choose either:
Note about Seven's titanium integrated hanger: Not replaceable or disposable. Seven's titanium derailleur hangers are the toughest in the industry. We've never had one break. Our new generation of thru-axle dropouts has yet to see a hanger damaged beyond bike shop service. We have no need for fragile replaceable hangers. Neither will you. Note about the UDH system: While Seven's in-house machined titanium UDH dropout is the toughest on the market, the hanger is replaceable. It is either aluminum or plastic and will get destroyed repeatedly over the life of the bike. Buy and ride with multiple replacement parts. |
