yeah my mate has the pair and loves the front but cant get the rear one to work too well. but yeah mine locks like, if not better,than a magura. i really cant believe it. i wasnt expecting it to be very good but it nearly threw me over the bars. it feels nicer than my mates hope trials which is very tempramental and feels different every day. i am really impressed with it and excellent service from bikedock....like it always is.
