Hi Guys, what would be a good option to start training to power with this particular crank ? I also have a Dura Ace 9000 Chainset in 50/34 which I know I could get a stages for but I'm wondering which route I should take ?? Pedals are not really an option as I'm a Speedplay user. Many thanks

    I went for a Power2Max Type S - ... anks-road/

    With that PM the original spiderings are redunant and I fitted BOR chain rings. I'm happy with this set up, I can fit 50/34 or 52/36 chainrings if need be. I did fit the 50/34 for the Fred Whitton and having the tools at hand for whipping the crank off, so I don't rely on a LBS and it takes 30-45 mins to do. Normally run 52/36 for most of the season up here.

    Stages for L/H crank - ... owgram-si/

    I'm sure others will have other options/thoughts but these allow you to keep the original crankarms.

  • FSA Powerbox looking good ... Problem there being I'd have to get rid of my current cranks ..

    Was going to suggest the powerbox as its BB30 an has that chainring combo. Only thing to remember is that you can only use four bolt chainrings.
  • Would that mean it could fit straight on a Caad 12 which is BB30A ? Or would I need another axle / additional spacers etc ?

    Apologies im slightly wrong there, you would need to get a BB386Evo BB purely because the spindle is longer (clue in the name the actual spindle is 86mm long hence you need the BB to help space it out)
  • Can anyone confirm if this FSA Powerbox would ever fit on a CAAD12 that has a BB30A Bottom Bracket. I'm speaking to my local bike shop here in Mallorca but the guy is telling me it will not fit and that he has looked into it ? He's saying the axle is too short or something like that and you cannot replace the spindle on the crank ? Can anyone else explain ? Is this right ?
