Aren't square taper bb's like nineteen dollars? Convert a twenty into some change and you're good to go.
|
well, I reckon all ya need is a square taper BB that and some square taper cranks to match and you'd be good to go
|
Your bottom bracket is english. You will need a square taper bottom bracket and some cranks to match.

I replaced the BB on my 07 pista with this one:
http://www.benscycle.net/index.php?m...th=188_247_680 Its good and all, but something is squeaking. Not sure if it is my cranks interface with BB. Or maybe the BB's interface with the frame. Or maybe just the BB itself. No big problem, just annoying. |

that depends on what cranks you decide to replace yours with
|
The size and style of the bottom bracket depends on the crank you want to use. Pick that first and then get the appropriate bottom bracket. Are you having some sort of problem with the ISIS crank?
|
its gonna depend on what cranks you get. Each crank has its own spindle length to achieve 42mm chainline.
This page should help get you on your way. http://www.sheldonbrown.com/bbsize.html Choose what cranks you want. Then find your cranks on sheldon's page, then make your decision on size. I chose the 107mm. |

THANKS! The frame takes English cups. The spindle length depends on the cranks you plan to use, since you'll have to chage your ISIS cranks too . Just follow the crank manufacturer's recomendations in regard to spindle length. What crank are you planning on upgrading to? Keep in mind that not all square tapers are not the same. Most cranks, such as Shimano use a JIS taper. However some cranks, such as Campagnollo and Sugino 75 track cranks, use an ISO taper. Although an ISO crank can be forced to "fit" a JIS bottom bracket, it will distort the interface and may fail. Just something to think about. |
i already have the cranks sorted out. i just need to find a right size square taper BB.
i have sugino RD 165 cranks |

Sugino's 68x103mm bottom bracket will do the trick. There have been reports of a chainline of 45mm with some newer runs of RDs, just for your information. I have them on two bikes and have never had a problem, though.

THANKS FOR THE INFO!!! i'll try to source one locally.

This might be of use to you: When I switched to a Dura Ace cog, It threw my chain line off a bit. I had to use bottom bracket spacers to move my bottom bracket out about 1.5 mm. So if you are planning on swapping the stock cog out, I suggest you do it before you buy a bottom bracket; so you can measure the rear chainline and select a bottom bracket accordingly. I have a 2007 Pista.
