The front derailleur is also part of this series and ensures precise shifting.

The saddle, a PROCRAFT Race III model, is held in place by a PROCRAFT Pro III seatpost. The saddle is clamped using the PROCRAFT SC-112A. The bike offers a reach of 381 mm and a stack of 569 mm, which in combination with a seat tube length of 500 mm and a top tube length of 544 mm allows for a comfortable riding position.
