Wow. what a tale. the actual pulley itself wore out. I always weighed the cost of the QCD to the cost of chain kits. Say $200 for a kit and $850 for the QPD. QPD gets ya 100K. Chain kits get 20K. Five times 200 equals $1,000 = better deal to get the QPD. The reason I never got the QPD was due to the cost of a replacement belt. One of those and the above math points to chain kits. Simple math now. Every other rear tire get a new chain kit. Ouch.
Wonder how the Turd bird pulleys are holding up? Someone has to have 10K on em by now…
Getting back to the original question, "is there anything to be wary of with these bikes?"
Yep. the butttass ugly tank.
