Mr ReillyA solid, reliable fit and forget unit. I have had a UN54 on my Giant for around 3 years and it only recently started creaking. As usual, a quality product from the Big S.
Mrs HowellThis Shimano UN55 is a great quality bottom bracket. This is the first replacement bottom bracket for my Trek Pilot road bike it's a good price and was easy to install.(once I'd got the old one out) The unit and the retaining ring are both metal and this was one of my reasons for choosing it. The bike now rides smoothly and quietly, no more crunchy noises! I would reccommend this as it's a well priced product and shimano.
Mr StenningA good basic bottom bracket. Excellent service from Merlin Cycles as usual.
Mr GriffithsQuick delivery, and good comms.
