Rear Derailleur

SORA Medium Cage Rear Derailleur 9-speed. Using shadow design, thinner assembly structure provides a more streamlined integrated fit. The pulley maintains consistent distance to the cassette for increased shift stability.

Dual Pivot Road Caliper Brake

Tektro R313 road caliper brake adopts a dual-pivot design to increase braking force and achieve the best braking performance.

Hub

R-AL6061 ED 14G*20H M9*100*108 /14G*24H M10X130X140 The front hub keeps the wheel spinning freely, and the rear hub allows you to coast or freewheel. Sealed cartridge bearings protect the hub’s inners from dirt and water.

Saddle

Gel inserts provide additional support to prevent the pinching of soft tissues while also cradling the sit bones in a comfortable position on the saddle.
