AndreZA Posted February 19, 2008 Share Okay, you need the cranks and a special front derailleur. FSA, Shimano and Campag makes them. Then you can maybe drop the rear cassette to 11-23 if not already.

Gman1834 Posted February 19, 2008 Share Botombracket? internal or external bearings? Link to comment https://forum.bikehub.co.za/topic/13373-compact-cranks/#findComment-253758 Share on other sites More sharing options...
andrewbell Posted February 19, 2008 Share Not sure. Just got the bike this morning. It is a Cannondale CAAD7 if that helps. Link to comment https://forum.bikehub.co.za/topic/13373-compact-cranks/#findComment-253788 Share on other sites More sharing options...
AndreZA Posted February 19, 2008 Share If it's only 9spd then it's got the older internal BB. You will need a new BB to go with the compact cranks. Link to comment https://forum.bikehub.co.za/topic/13373-compact-cranks/#findComment-253793 Share on other sites More sharing options...
amateur Posted February 19, 2008 Share I've just put a compact on my Cannondale and all the we have changed is the BB, we didn't change anything else. I borrowed IanJ's to try it out and ordered my nice new Chorus one, hopefully I'll get it today or tomorrow. If you want more specific details, PM Zaskar or Cruxpearl, they know the Dale's backwards and will be able to help you.

lowracer Posted February 19, 2008 Share ok, so this explains why amateur puts bumps on zaskar's adverts... Link to comment https://forum.bikehub.co.za/topic/13373-compact-cranks/#findComment-253805 Share on other sites More sharing options...
Zaskar Posted February 19, 2008 Share ha ha, the Chorus cranks are Amateurs, off her bike. I just posted them the other day cause i took the pics and was logged on at the time. But regarding the compact question, i would go for the Shimano R-700 compact set. They are not assigned to a specific groupset, as they will work with Dura-ace Ultegra and 105, but as far as i know they are Ultegra quality. Im not 100% sure if they would work with your 9sp set-up, check with the guys from CoolHeat first. But if they do you will need to replace your BB with the newer external bearing BB cups and possibly your front derailleur as well? It might pay you to look at a second hand 10speed groupset, i remember seeing a 105 set here a few days ago. Good luck and let us know how it goes!

Gumpole Posted February 19, 2008 Share another alternative (a lot cheaper) is just replace the rear cassette with a 12-25!, (39-25 = same ratio almost as 36-23) Link to comment https://forum.bikehub.co.za/topic/13373-compact-cranks/#findComment-253839 Share on other sites More sharing options...
