The Up-and-back risers arrived today. First impressions are they are well made and look a solid piece of kit. The polar opposite of that is the cap screws they supplied. They are utter wank and no earthly force could convince me to keep them, except only for the purpose of taking pictures.
Good bits: quick delivery, good price, well manufactured, good fit, ergos feel great but a test ride will be the true test, no collision issues evident.
Bad bits: supplied cap screws, may need to tweak the throttle cable routing as they are a bit tight on full right lock.
