Notes on the fit

This brake kit fits on smallframe vehicles whose front wheel is still fixed to the brake drum via four relatively central wheel nuts (closed rim, 4-hole inside).
It is not suitable for open rims with five external wheel nuts (there are other versions for this).

Requirement: 10 inch, closed rim (4-hole inside). For 9 inch models, the conversion only makes sense after conversion to 10 inch.

FAQ

On the closed rim, the screw connection with four nuts is located relatively centrally on the brake drum (4-hole inside). On later variants (open rim), there are five nuts that are visible on the outside. This kit is designed for the 4-hole inner variant.

No. The brake caliper is not included in the kit. The kit is designed for brake calipers with a radial bolt connection (82 mm). Recommendation: BGM2506TTB.

According to the concept of the kit, no changes to the original fork or mudguard are necessary. This means that the conversion is reversible.

The kit is designed for 10 inch models. With 9 inch small frames, the conversion only works if you have previously converted to a 10 inch closed rim (4-hole inside).

Anti-dive reduces the front end diving under braking. This can make the ride feel more stable, especially with more powerful setups and a sporty riding style.

Brakes are safety-relevant. Only install them professionally, then bleed them carefully and check their function. Depending on the country, approval or registration may be required.
