Bicycle Electric Lifting System
Motorised lifting column with a quick-release clamp that sets a bicycle at the ideal working height in seconds — controlled from the handpiece or the foot pedal.
Multi speed screw-on freewheel series, DF-601 to DF-959 — non-index and index types, ratios from 14-28T up to 13-32T, in black, brown, CP and gun grey finishes.

The DF Series multi speed freewheels screw onto any standard freewheel hub, in non-index and index types with ratios from 14-28T up to wide-range 13-32T — a model for city, trekking and MTB drivetrains, finished in black, brown, CP or gun grey.
The series splits into non-index freewheels (DF-601/602/603 and DF-701/702/703) for friction shifters and index freewheels (DF-611 through DF-959) for indexed shifters, all on the classic screw-on threaded mount.
Ratios run from 14-28T through 13-32T across the range, and finishes include black, brown, CP (polished) and gun grey — pick the model number that matches the shifter type, ratio block and colour; the full table is shown in the gallery.
