Hello guys any 1 know what moden chain tenisoner fits the 198A my 199B as a monden 1 on but not sure what its off I wanted the enclosed typ cheers bondy.

Hi Bondy. The easiest way is to take your 199B tensioner off and walk inside and switch on your computer and look through the online bike shops which sell trials items and find one that looks the same as yours. If it is an accessory one it should have a brand name on it somewhere. Good luck. Graham.

Cheers Graham ill have a look

Why am on the suject off chain tenisoner. Is the a standard lenth off chain for the 39 11 sprockets?

Bondy, I think the alloy gas gas ones from in motion may be just the job
