Question: Does this item include both left and right arms?
Document: I was a little worried going to these shorter arms for my 29'er, but after reading what Sheldon Brown and others said it seemed like it wouldn't be a problem, and I don't think it is. As they said you get used to it rather quickly. Actually if you are a hard masher like me it may be easier on your knees having shorter pedals. 32 and 20 seems to be the right SS gear for moderate hills on my 29. For a 26 I think 32 and 18 was better.
Made in Taiwan, not China. Arms are forged alum alloy. Was an upgrade on a single speed Fat bike & works great.
It's a nice lightweight crank. I turned my 21 speed mountain bike into a 7 speed with this. I like it, been riding it for a week or so, no problems. It's the cheapest crank I could find. Shipped fast too.
I bought one of these awhile ago to put on one of my folding bikes, a 20 inch wheel bike. This is a good product - has a light weight and clean look to it when installed on your bicycle. I like to use a 32T chainring with many of my bicycles, makes it easier to pedal. I wished they made one of these with a little longer crank arm, like maybe 165mm or 170mm. I will buy more of these now that they sell them on Amazon.
