Good product

Comments On Dec 27, 2015:Purchased o-ring kit to replace a badly worn stock set. Everything fit well with easy installation. Even sent the spacer for the countershaft, a must have when installing a wider chain like an o-ring. Original front sprocket wasn't too bad of shape, but why not spend a couple more bucks & replace it all.

Great for the price

Comments On Nov 25, 2015:Had the sprockets and chain on the bike for over 7 months now, the sprockets show little wear and the chain stretched very little, from hard Sandy desert riding and mx track racing to muddy trail riding they hold up. Can't beat the price!!!
