Focus Cayo fitting help Shimano 105

titchlmd

I have just purchased a 2nd hand full Carbon focus cayo frame set which I believe is 2013 model.

I'm trying to fit shimano 105 group set to it and having problems with the bottom bracket.

I have an SM-BB5700 is this the correct type?

I'd like to post some pictures of the frame but don't know how to....thanks in advance

As per your other post I think the frame uses a pressfit PF 30 BB shell, so you will need adaptors to use you Shimano HT II crankset. What BB if any is fitted to the frame now, look for identifying markings on the BB cups if fitted. You won't be able to use you SM-BB5700.

From the Park Tools website http://www.parktool.com/blog/repair-help/

"The PF30 system uses an unthreaded frame shell with an inside diameter of nominally 46mm. The inside of the shell is a straight bore, without the stops or clips of the BB30 standard. The shell widths are 68mm for road bikes and 73mm for mountain bikes."

"The cartridge bearings are held by a plastic or aluminum adaptor. These are then pressed into the shell. The PF30 bottom brackets accept the BB30 compatible cranks with the 30mm diameter spindles. Adaptors are available to use non-BB30 cranks in the PF30 frame shells. The bearing service in this article assumes the PF30 bearings are installed into the PF30 frame shell."

you want a PF30 to BSA adapter like this one:

£17.99

can use your shimano chainset instead of a BB30 one then (screw the shimano bottom bracket into the adapter once it is installed)

edit: you can go the wheels manufacturing route, but you'll have the same short life / clicking bearing issues as a BB30 bottom bracket then - i'd go with my suggestion to avoid this

That reminds me that there is also the Praxisworks BB adaptor. http://www.praxiscycles.com/product/shi ... ersion-bb/
