Review on πŸ”§ 37 Tooth Steel Rear Sprocket by JT Sprockets - JTR212.37 by Roy Whetstone

Revainrating 5 out of 5

Great for Grom to make pulling out easier.

Quick assembly on site. I have 14t -1 of the 15t in the front and 37t in the rear. For every front tooth there are 3 molars, so I think that's 40 tons. I would recommend if you only use thunder for retarding or rear wheel to get a 40 tooth rear sprocket and up. It is very easy to deal with him, since Thunder is weak and too weak. Get about 60% springs and a stronger clutch disc. You are hired!

Pros
  • Annual trial period
Cons
  • Repair
