Bike Mailorder Chain tensioner 10mm - pair

The chain tensioners keep the wheel at least after 2 days and partially strong kicks where it should be, although I want to have noticed a hint of shifting of the rear wheel, but it could also be imagination. 2 drawbacks: The retaining ring for the axle is narrow, i.e. it could possibly eat into the axle thread and the locknuts could use a rubber ring that secures the nuts from coming loose.

Were delivered with my Token bottom bracket. These chain tensioners are ideal for my Leader 725 singlespeed.

Affordable alternative and it holds, even if it doesn't sit 100%ly...

After cutting and filing, chain tensioning was no longer a problem. Unfortunately, the theoretically fully enclosing stop doesn't really fit if the end of the dropout isn't designed slim in vertical extension. In dropouts where the upper 'leg' aligns directly upwards at the back, reworking is unfortunately necessary, otherwise the stop wobbles as only one side of the stop lies flush. The O-ring for the axle could be a millimeter thicker to protect the axle thread. At the low price, you really can't go wrong.

Reliably tightened the chain on the dirt bike...
