 319  Sarasota, Florida |  Subject: Crank lengthBought my first road bike and have been on the same mountain bike for almost 10 years. I'm comfortable on the mtb and have a lot of the handling built into muscle memory. The immediate difference I noticed is crank length and muscle activation on the stroke. I don't have any specs on my cranks but the road bike must be shorter and I find it annoying. Even more annoying I scraped the pedals on the pavement because the clearance is worse than my mtb. I played with the seat but the cranks have to be different. I'm thinking about talking to the shop to lengthen them but just wanted to check on here to see if there is actually an advantage to having shorter cranks? I feel like I'm only using half my muscle now. Also, I don't have clips or clipless on either right now. I was fit for my mtb but I'm pretty sure the road bike is 2 sizes too big but still comfortable after dropping the seat and bars.. |

Here is a discussion on that subject from a couple weeks ago. Yes there can be an advantage to shorter cranks, it's all about fit. I ride a MTB as well, most people riding a mountain bike like longer cranks on the MTB than on there road bike. I feel its an advantage when going over logs, and up steep rocky hills. You will get opinions all over the place on this. |

Master 10208 Northern IL | Subject: RE: Crank length Yeah, it's largely about fit. The road bike is going to be setup differently from the mountain bike and it's going to feel different too. Look into that to make sure you have it right. This can make a difference in how it feels. Also, the crank size for both is likely stamped into the cranks in small type down near the pedal connection. It's fairly small, easy to miss and is probably a number around 170-175mm. Could be on the inside or out. |

Champion 10668 Tacoma, Washington | Subject: RE: Crank length Originally posted by runtim23 Even more annoying I scraped the pedals on the pavement because the clearance is worse than my mtb. The cause is that you're pedaling through corners, not that the clearance is less (it is, but that's not the cause). |

If the cranks are actually shorter then they would also help with this (slightly), not make it worse. |

| 319 Sarasota, Florida | Subject: RE: Crank length Thank you. I'm surprised I missed that post and will review it. I"ll probably do a few bricks before I make a decision. |
