High-end bike parts - Made in Germany.
FRAEZEN's claim is to develop and manufacture high-quality and durable parts for your bike. In order not to leave anything to chance, all necessary steps, from the first draft to the finished product, are carried out directly on site in Leutkirch/Allgäu.
Both the construction and the production take place in the in-house production facility in the beautiful Allgäu. The noble bike parts are tested on the local trails of the region and in the international racing events of the Enduro World Series. The great advantage of on-site production and testing is obvious: short distances enable quick changes and improvements during development and result in products of the highest quality in series production.
World's first one-piece derailleur cage!
The KAEFIG is the first one-piece rear derailleur cage system that is designed for use on enduro and e-bikes and is of course designed and produced in Leutkirch/Allgäu. The noble piece is lighter and at the same time more stable than the original. The one-piece construction increases the torsional rigidity of the rear derailleur and thus enables more precise gear changes. This is particularly noticeable under high loads and in heavy gears. The SRAM version of the KAEFIG has a second hole for the clutch spring, which ensures a higher spring preload, which significantly reduces chain slap. Due to the ceramic hybrid bearings in the rear derailleur rollers, which are additionally greased with special grease, the service life increases significantly. Larger rear derailleur rollers change the relationship between roller and cassette, which affects the shifting processes and could lead to frequent defects when used on enduro bikes. Therefore, the development deliberately avoided oversized pulleys. Another highlight is the Narrow Wide Form on both rear derailleur rollers, so that your chain stays in place in every situation.
