Warning - semi long and boring read, but I'd love answers.
I'll be the first to admit, I'm not a full book on anything cycling, except for the pedalling part, and the changing of tyres (which takes me a good six minutes on a quick-nothing-goes-wrong day).
My roadie at the moment isn't very great (masi nuova strada), however I've prioritised that i'll chuck a powermeter in it before upgrading the frame around it.
Ergomo pro power meter is what I'll go for - it's what is on my TT bike, so I can keep the same computer and just buy a sensor, plus I really really dig the layout, the altitude part and the % gradient, etc. Never owned a different power meter and do not plan too.
Essay over. Sorry guys.
These are the options I can get:
ergomoÂ® pro ISO square BSA 102 mm
ergomoÂ® pro ISO sguare BSA 111 mm
ergomoÂ® pro ISO square ITA 102 mm
ergomoÂ® pro ISO square ITA 111 mm
ergomoÂ® pro Octalink BSA 109,5 mm
ergomoÂ® pro Octalink BSA 118,5 mm
ergomoÂ® pro Octalink ITA 109,5 mm
ergomoÂ® pro Octalink ITA 118,5 mm
ergomoÂ® pro ISIS BSA 108 mm
ergomoÂ® pro ISIS BSA 113 mm
ergomoÂ® pro ISIS BSA 118 mm
ergomoÂ® pro ISIS ITA 108 mm
ergomoÂ® pro ISIS ITA 113 mm
ergomoÂ® pro ISIS ITA 118 mm
Now, here's where I have a stony cold look on my face. I don't know what I don't know. The dura ace stuff on my TT bike is pretty funky, so my eventual roadie will have them, err, answer the questions that I want to ask
edit. What one do I buy, and why? <-- that seems to be the question. Any further bottom bracket education however, will be thoroughly appreciated.
ISO square is the old square tapered stuff
octalink is the older style BB from about 3-4 years ago/
ISIS i belive is the new hollow crank stuff
Then you have either italian or British standard threading, then the BB width two sizes
I might be wrong on the cranks, but basically what bottom bracket are you runnign? once we know that it's probably a easier choice
