Good chain

Comments On Feb 04, 2015:Good value for the price. Seems to last. Son is wearing chains out faster due to more aggressive riding. I think this chain wears well for the money.

Good for the price

Comments On Mar 18, 2014:This chain is worth the money but if I had money to spend on a chain I would just buy a Renthal I expected more power that's the only reason I gave it 4 stars but overall a excellent product!
