Brant: ah, I'd seen a pic of someone else's BP that had the rear brake routed that way and liked the look of it. Maybe I'll reroute it then. Had thought the stem may want to come down a bit but thought I'd test ride it first before cutting any more steerer off.
Chainslapp: havn't riddn it properly yet or bedded the brakes in so can't say. Major pita to set up and bleed though, I got through nearly half a litre of mineral oil and the rear is still slightly spongy. They are known for being a pain to bleed though apparently.
