Avid BB5's sets arrived this morning, took me about 45 mins to fit the front and rear along with new discs, fairly easy job, ok I could maybe have done it quicker, but took my time, double checking etc. Out for short test ride this afternoon...Wow what a difference to the previous Zooom brakes, im told they get better after bedding in as well. Ok hydraulic would have been better again , but im no speed or mountain biker and for the relaxed cycling I do they will be fine. Just mudguards to fit tonight, and if it arrives tomorrow a rear rack. I love the bike, only sight downside is battery life, but hoping as I get more strength in my legs this will be less of a problem.
