      Replacing a crankset on a gary fisher Wahoo 2010. 8 speed

      I found a shimano but its 9 speed.

      Rookie question, can i get this crankset and work without problems or should i stick to 8 speed.

      Here is the link for the crankset, looking for options less the $100 bucks. Suggestions!

      The cranks from that link are 7/8 speed compatible….

      Just make sure you remember you’ll need a new bottom bracket if your old one is not compatible with new crank set. That price does not include the BB.

      I replaced the 8 speed crank on my 2013 Trek Marlin with a 9 speed XTR crank and it runs just fine with the 8speed chain and derailer. So I don’t think you will have any problems.

      9 speed cranksets have narrower chainrings, as their chains are narrower. So using a wider (8-speed) chain will work just fine on a 9-speed crankset, which is what you want to do. (But note the opposite is not true: a 9-speed chain will [i:3assywh3]not [/i:3assywh3]fit on a 8-speed crank, as the chainrings are just too wide for the narrower chain.]

      PS It’s been mentioned, but that Amazon crank you listed is not 9-speed anyways.

      Cool, I just got the crankset [url:zm8yn3z1]http://www.newegg.com/Product/Product.aspx?Item=9SIA1G80CY8778[/url:zm8yn3z1]

      Stripped the arm 😳 so i need a new BB since I will need to cut it with a power electric saw.

      They’re all good quality. Just get a basic one like this. Make sure you get the same dimensions off the current one.

      What do you mean you "stripped the arm"? Are you saying you can’t get a crank arm extractor in to remove the crank because the threads are stripped?

      Yep, stripped the arm!!! However, I was able to take it off. Live and learn !!! 😆

      Now I need to get the correct octalink bearing and will be good to go! Suggestions !

      Shimano BB-ES25 Octalink V2 Bottom Bracket

      size =73x121mm

      or 73x126mm

    • #120322

      I imagine 121mm is fine. But when you install the new crank on the new BB, just make sure the small chainring doesn’t hit the frame. I’m sure it’ll be fine, but that’s the concern when getting a shorter BB.
