Eek, dunno how I missed those Troll forks – I think it’s cos I was only looking at the Ison website – but they seem to be exactly what I’m after. Bit long, but that’s no bother: slack is good… I shall get in touch with ID and the wonderful Brixton Cycles. Thanks for the suggestion, psling!
Those mounts are good, hero, but they only really work with the Blackburn lowrider rack which, in turn, don’t work too well with Ortlieb panniers and others that need to clip around a horizontal bar (that big plate of metal gets in the way…) but thanks for the hint – those clips have a multitude of uses.
The idea of having both canti and disc mounts is that if something should happen to the disc caliper/rotor/whatever the tour can be continued by fitting an easier-to-source rim brake. I read of a couple of chaps touring with disc brakes who carried a spare HS33 rim brake with them for just that eventuality – that’s what inspired me.
Any more suggestions always welcome!
