This is a square tapered crankset. It came with a liitle plastic guide to properly space it with your front derailleur. Installed this using the Park Tool crank remover. I've put around 500 miles on it and I haven't noticed any issues since installation. The 34 tooth comes in handy when fatigue sets in and there is still that one last bridge or hill. Overall another great purchase from Amazon. Read more

Muy buena calidad, se siente la diferencia. Mi bicicleta GW trajo un kit de arrastre genérico de baja calidad que duró 8.000 km. El Tourney se siente mucho mejor y funciona perfecto con el grupo Read more

Sturdy, good weight, well built. Read more

I've only done two rides with this crankset and several of the teeth on the large chain ring have already broken. It's still functional but it's surprising for a Shimano product. Read more

I decided to use just a larger front chainring and bigger rear gears Read more

I was able to make the crankset work on my 2006 Specialized Roubaix Pro. It has custom freewheel gearing of a mountain bike 11-34 Nine speed cassette. I live in a very inclined hill area. I was able to make it work on my bike by changing the bottom bearing bracket to a smaller spindle axle. My new chain was cut down a few links to make it work, due to my old chain ring being a larger size. I spent about an hour mainly climbing uphill on and off 7 miles. So far so good, I have no issues or complaints over the rigorous testing I had done on it. Read more
