Great Freewheel!
Put this on my 29" MTB to replace the no-name freewheel that was already on it. Not only did the extended range of the 34 tooth gear make hills easier, but the shifting is MUCH better than on the off-brand product. It coasts better too. It is heavier though, but marginally. Great inexpensive freewheel for those who like a wider range on a 7-speed budget.

Great Freewheel
I bought this on a budget, and I do not regret the purchase. I was going from a 6 speed to a 7 speed, and it fit perfectly. it has gives me a smooth ride and helps me get up the hill on my commute to school. I can't wait to try this on my local trails.

Hi. Just wanting to make sure this cassette will fit a 2014 Trek Superfly 24. The original has done the bearing and the only info I have is that it's a 14/34 in a 7 speed. Really disappointing original component quality. Hope this Shimano unit will be alot better.
