I’m not associated with bikeberry or partial to BBR parts at all- I just buy various brands at random when convenient, to test out. This spring was never installed- I just labelled it once upon a time as being the bikeberry upgraded (stiffer) spring. Although I’ve never installed or tried one of these out- it should be safe to say it’s stiffer than standard… If not- we both got ripped off😂
I’m almost positive it’s branded as “BBR Stiff/Racing Clutch Spring” or something like that, but I can find the name on receipt for anyone interested.
(in which case, contact keaton@mbtuningparts.com for this info)
New and used clutch shafts (with standard spring) also available which you can retrofit this stronger spring onto- please email- would happily set you up a custom deal! I have even more parts available than posted here- especially small odds/ends and random other brands I once bought to compare!
Also note that any of these springs- therefore clutch grip- can be tightened or loosened +/-20% or so (good to keep in mind). If set too tight, usually you won’t be able to pull in the clutch far enough. And if too loose- you know what might happen haha. The nut that tightens the spring has an edge which indicates the typical adjustment position.
Several types of clutch shaft bearings available to choose also- rubber, metal, or non-shielded clutch shaft and crank bearings- name brands!
