          • Mountain biking

          I bought this crankset to replace the existing XT crankset on my mountain bike. At first I was concerned about using the 170mm instead of the 175's that I had been riding, but I didn't even notice a difference - except for maybe a few less pedal strikes while on the trail. I'm 5'9" and the cranks feel no different from the 175's that I replaced.

          Great Shimano quality, great JensonUSA price!

          • Training and racing

          Shimano xt products are my Favorite components for all around riding in general. They're are very reliable , strong and easy to work on . They're stiffer than xtr and give me more for my money. I would only get the xtr if they're on sale. I wouldn't consider any other components other then shimano for MTB.

          180mm cranks feel powerfull

          By Brian the lion

          from Natick, MA

          Verified Buyer

          Pros

          • Bearings smooth
          • Nice bearing fits
          • Nice Finish
          • Stiff

          Cons

            Best Uses

              I put these on my cross country hardtail. I tried the 180mm length for the 1st time and love it. I don't seem to be banging the crank arms on rocks and obstacles any more than usual. The advantage is that it feels like I'm spending more time in the most powerful part of the pedal stroke. I seem to be able to drop the cadence which also helps maintain clearance in rock gardens etc. These cranks feel stiff and efficient. Shifting is great.

              Pros

              • Easy Instalation
              • Less expensive than rings
              • Light for the price
              • Solid feel

              Cons

              • Chain line off
              • Shifting

              Best Uses

              • All Mountain XC
              • All mountian XC

              I bought this to replace a 3 piece XT that came with the bike. Enduro pro 2003 vintage. I had just bought a set of FSA chain rings when the XT went on sale. Its a easy install but it moved the chain line about 1/8 of an inch outward using recomended shim placement. Overall it shifts poorly compaired to the FSA rings ( they were effortless and smooth). I bought this for the crankset not the chain rings. Its a great product with a very solid feel.

                Tried and proven! These have been around for a while now and there's a reason why they are still selling well and so popular. It's affordable, relatively lightweight, great quality, and BB design is solid and hassle free. Get one if you want a problem free clean looking set of cranks.
