I have a 'vintage' Manitou SX ti fork which has an old 69mm post mount for disc brake.
The bikes been running rim brakes forever and its time to put a disc on it. I have an avid 160mm juicy.
I can get an adapter to convert from the old 69mm post moint to an IS mount from the likes of WooleyHatShop BUT it says I will then need to run a rotor 20mm larger. I dont want to run a 180 or 185 rotor.
Could I not just get a 140mm juicy IS adapter, use the 69mm to IS adapter and then use the 160mm rotor??
Next question – Do Avid do 140mm front IS mount adapters?
There was a post on STW I found where someone was selling a set of ultimates 140mm front AND rear so this suggests such a thing does exist, but google searches turn up bugger all.
Help anyone.
Cheers,
