Just an update on this..
I had a very quick email reply from a guy called Rick at Works Components. They are planning on making some headsets to work with Canyon Nerve frames in the next few weeks, sounds very promising..
Sounds like they would make something similar to what fivespot machined (above)?
see the reply I got..
The reason current headsets dont fit is the bottom headcup style – they have gone for an IS standard lower headtube where the bearing drops straight into the frame – there is no headcup so a standard cup wont fit.
We would need to make a cup to suit this size, essentially replacing the bearing with an interference fit cup – I expect we could alter head angle by 1.5 degrees but it would mean using an external cup so extra stack height would be a necessity – this would mean a 1.5 degre headset could alter actual head angle by 2.2degrees due to the extra height of the lower cup.
The lowering effect on the front end when slackening the head angle would be offset by the cups extra height so front end height would be raised by less than the cups actual height of around 10mm – likely around 5mm in actual effect.
Price would be in-line with all of our other headsets – around £79.99
We are due to run off a new headcup to suit tapered steerer tubes in 44mm ht frames, we wiill be able to produce some headsets to suit your bike at the same time – should take around 3 weeks start to finish.
