hollowtech 2 BB spacers - do I need them?

[just jim]

I have a new Tiagra Hollowtech BB to install, but it doesn't include any spacers- it's just in two parts. Should some have been included? I'm fitting a compact double chainset.

Hi

Hope you get an answer, as when my new frame arrives I'll need to do this too -

I found a guide

and if you look on yoootube theres a few videos. As for the spacers I'm not sure, hopefully someone can help!

You might, you might not

It depends on the width of the BB shell, and the distance between the assembled BB. measure the BB-shell width. Measure the distance between the internal faces of the BB when its got the plastic tube between it. They should eb the same..

i need one on the drive side of two of my road bikes and none on the other bike, so its a bit hit and miss i reckon. It depends on the bike

I'll do that thanks!

At least you haven't asked it the BB needs facing

If it's any help my cups are fitted to an English bottom bracket and a tiagra double chainset- no spacers used -think this is the standard set-up on all arrangements of this kind-I have two bikes like that.
