Let us know what you'd charge. In the meantime I'll probably see if I have tire clearance for offset bushings. I did discover today that the 650b Jekylls are almost a full degree slacker than the 26" models, so it may not be necessary. But then again, that's where the DYAD's climb mode is awesome.
That's how it works generally. The SI headset is a bit trickier... that's why there aren't anglesets manifactured for them, along with the fact they aren't widespread.
Same for most of the integrated headsets, not just Specialized. I decided to change frames rather than deal with it. Will never biy another frame with either integrated headset or press-in BB again ...
Is your headset not Cannondale's System Integration? I've wanted to go the Angleset route but the SI on 2015s doesn't allow for that.
Also, can you post a close-up of the bushings?
Yes, standard cannondale SI headset. Nobody makes anglesets for them, I made it myself. There's little space in that headset size but it can be made to work I've been using it for a while whitout issues.
Pictures were taken when I had both angleset and shock bushes:
That looks great, very nice work, I would love having one of this angleset headset for my 2013 Cannondale Trigger 29er!!
