Expert 1130 Fernandina Beach, FL | Subject: Power meter question. Sorry if this has been covered. I need assistance choosing a power meter. I have a 2012 B16 with megaexo BB. Not really finding many megaexo power meter options. Are BB's interchangeable? (sorry if that's a dumb question) Or do I need to use adapters? Looking at purchasing a used one but not yet sure what it is I'm supposed to be looking for. Thanks for the help |

Expert 1130 Fernandina Beach, FL | Subject: RE: Power meter question. That's for the advice checking out dcrainmaker. I'm pretty aware of the different brands and types and know I want crank based. My problem is finding one compatible with my bike. Didn't really see that info on his site though |

Veteran 720 Aurora, Illinois | Subject: RE: Power meter question. I believe that's the same style as the GXP bottom bracket. If you get a quarq, you could pick up a bottom bracket from them for $35 (they also have a ceramic version for $200 but I've heard mixed things on those). What crank do you have? Another option is to go with the stages power meter and just replace your left crank arm. |

Expert 1130 Fernandina Beach, FL | Subject: RE: Power meter question. I have the stock FSA crank on there now. I think there's some issues with Stages on Felt bikes due to the clearance on the rear brake. Thanks for the advice on the GXP BB. That's what I thought I read but wanted to make sure that it would be that easy (just purchase a BB) Edited by rjrankin83 2013-11-29 11:30 AM |

Member 326 | Subject: RE: Power meter question. Originally posted by ultramike Stages is supposed to be releasing some FSA MegaExo & BB30 cranks in January 2014. Here is the reply I got from stages when I contacted them about FSA cranks. I have a Specialized Tarmac with FSA cranks. Hi Dwayne, It should be early January, possibly up for pre-order even sooner. Sorry I don’t have an exact date – but they’re definitely coming. We’re rolling out just left arms first, then full cranksets. Hopefully more info soon. I’ll toss your email in the saved box and try to get back to you when I know for sure. Thanks! Amy Shepard Customer Relations (800)778-7218 [email protected] www.stagescycling.com |

643 | Subject: RE: Power meter question. I'm the one who wrote Stages won't work with B16's. What I ended up doing is replacing the BB with a new Dura Ace one (like $40 and not too hard to install if you watch a youtube video) and getting a power2max crank based system. They are actually having a sale now: "$125 off all power meters with BOR chain ring set. Use code blackfriday" which sucks since I JUST bought mine 3 weeks ago and that would have been nice to save that much. If I remember right, the FSA Gossamer, Rotor 3D, and Rotor 3D+ max will fit the BB I installed. I went Rotor 3D for the supposed better shifting and the ~100 less grams. 3D+ is even lighter and stiffer but too much for me. Not really a weight wennie but since I'm adding weight from the PM, I thought the little extra cost was worth it. Don't limit yourself to a PM just based on the BB. You can always change it out. Edit: Even with an FSA option, I don't think stages will work. If you get a tape measure out and do what they say, there shouldn't be enough clearance. I did this on an Ultegra crank I installed and for sure it wouldn't fit. The FSA bowed out slighty more than the Ultegra so maybe it would be a closer fit but I'm 95% sure that it would't fit a B16. I sent Stages a picture with my Ultegra crank installed and they said no way. Edited by Blastman 2013-11-29 4:02 PM |

Expert 1130 Fernandina Beach, FL | Subject: RE: Power meter question. Blastman- Thanks for the insight. That's what I was hoping to hear. Pretty much it looks as though I'll just have to add about $50 to the cost of the powermeter for a new BB. |

Looking at purchasing a used one but not yet sure what it is I'm supposed to be looking for. Thanks for the help To answer your question more specifically, yes, bottom brackets are interchangeable, but they are not always fully compatible. For example, you cannot run a BB30 crank on your bike...there is no adapter that will work because the BB30 spindle is too large for your BB opening. However, you can use a GXP crank on a BB30 bike using an adapter. I don't know all the specifics of what is compatible with what...but since you don't have a BB30 bike, just make sure you don't buy a BB30 crank and you should be okay. |

20 | Subject: RE: Power meter question. I installed a TRP 925.1 brake to eliminate the brake clearance issue with a stages crank. I paid $25 on ebay after a month of searching, they run 125 new. This brake is within the chain stay on my b16. My plan was to purchase a different Shimano crank and use a stages power meter. My road bike is 105, so this plan would make swapping rather easy or buying another crank arm cheap. With that said, I found a GXP Quarq crank on ebay for $650. A new GXP bb later and I have a power meter. |
