Review on 🚵 GANOPPER MTB Crank Arm Set: Top-notch 104 BCD Square Taper Mountain Bike Crankset in 152mm, 165mm, and 170mm by Aaron Urena

Conclusion: Feels quality, looks clean, they bulge out of the frame a bit more than the stock cranks on my bike but feel no different. The base model Rockhopper had 175mm cranks, but the 170mm cranks are pretty much the same. Remember that you will need to purchase a crank removal tool. The chainring can be either outside or inside, I had to put it inside to help with my chain. Narrow wide teeth are wide to the tip of the tooth. If I were running 11 or 12 rear gears with a thinner chain I would consider getting a front ring that tapers towards the thinner tooth tip.
