The Vertigo has had a wee bit of an update. An Eriksen 30.9 post, just cos. An xtr shifter: the clamp mechanism is narrower and has more lateral adjustment. The jones bars make setting up rapidfire a touch more difficult and this helps. Functionally seems similar to the Saint shifter, but the multi release (2 shifts to smaller cogs possible in one go) is excellent.
An ignitor on the front. Dunno if its a wear issue (it doesnt look too worn), but the ardent seems to have given up on any form of traction. Fortunately. ignitors still rock.
