Here are some images of my bike... could someone advise what sort of bike rack I should be looking for... I am hoping to support two sets of 23ltr avenir panniers so want something prety sturdy but cheap!!
It looks like you've got a fairly standard set of bosses so it's likely any reputable carrier will fit (they're adjustable - usually the upper arms can be lengthened/shortened to meet the bosses once the lower fixings are in place).
I've usually used either Blackburn racks or Tubus. Neither type are cheap, unfortunately but very robust.
