bottom bracket help/advice

[mr-marty-martin]

i just went down to get a bb from the lbs, a campag square taper one, veloce

he told me its the same one as i had and will be fine ( i had the old one with me aswell)

but, went to fit it today and it pulls the crank to close to the frame, so the chainring hits the frame

i susspect the spindle is the wrong size?

 

[Theseus]

Are there any product codes on them?

 

[mr-marty-martin]

well i no the measurements match up, but the spindle length ( or whatever you call it ) is longer on the old one, but it doesnt seem to tell you length of that anywere.

 

[mr-marty-martin]

the old ones like this http://cgi.ebay.co.uk/Campagnolo-Ve...s_SR?hash=item518b5d3d15&_trksid=p3286.c0.m14

note the flush plate

were the new one is like this

http://cgi.ebay.co.uk/New-Campagnol...s_SR?hash=item5ad2b00652&_trksid=p3286.c0.m14

note the bit that goes in, so there's a little lip

im not sure if thisis just that ons an old and ones a new design

Just new design. You need to measure the axel length. You need to replace with one that is the same length.

The shell (the outer bit) will be 68mm so they are the same, but it's the axel length that's key - take it back and get it swapped for one that's the same length.

will do cheers, one thing noticed is that a dnt think it says about the axle length on the box...

shame this was the last one of the bb's he had at the old price, so i'll have to py campags new rates now...

Veloce BB's come in 2 axle lengths. 111mm and 115.5mm. Looks like you need the longer one. IIRC they aren't marked with the length so you need to measure them. Possibly the LBS have given you a 111mm.

 

[Mr Pig]

I can't believe he gave you the wrong one when he had the old one in front of him. If you sit them side by side the difference in length is obvious.

 

[mr-marty-martin]

yeah i noticed the differance straight away

luckily he had a 115 in and swaped it, and luckily it wasnt the new campag stock or i would of had to pay the new prices...

still cant get over £25 for shimano cleats...
