Hi guys, I'm new here and need some help, I have just resurrected my 97 M-TRAX 1000 for commuting to and from work. I changed the the crankset, chain and rear cassette, during this I found the bottom bracket was rough and noisy. The original is a BB LP25 and i was thinking of replacing it with a BB UN26E as all the dimensions look correct but it appears that on the old one the drive side is plastic threaded and on the BB UN26E it is the opposite way round. Does anyone know of a direct replacement or equivalent for the BB LP25??
