There was a post recently covering this but it did not really answer my question.
I have a santa cruz bronson mk 1 with two 0.5 degree offset bushings. All good except some pedal strikes.
One of the posts on the previous thread suggested that 1 degree at the bushings has a bigger effect on the bb height than 1 degree at the headset. Is this the case? I cannot really get my head round it bring different.
Anyone help?
Yes it is right. Offset bushings lower the suspension, which has the effect of slackening the head tube angle. So talking about a "1 degree bushing" is misleading, what they do is shorten the shock, the amount of lowering achieved depends on your suspension linkage and the head angle change depends on the lowering and the bike size. An angled headset has the effect of changing the shape of the frame itself (as if your bike had been welded up with a top tube a few mm shorter). This has only a slight effect on height for trigonometrical reasons.
Thanks. I can see the shortening of the shock dropping the bb but I thought the impact from the headset would be similar. I have got one in the post so will give it a try! Cheers
they do not do this and if they did travel would be affected what they do is move the position of the bolts for the shock but the eye to eye is unaffected in terms of length between them but NOT locationwhat they do is shorten the shock
Everything else you said is true- ie bushes affect BB more than headsets
