Can you tell wich Marin is? And year. I think I have a photo of my UN54 and UN52 in my other computer. I have chage the BB last year and I have made a photo to compare weight. Mine is a 96 Team Issue.
I ran the Sugino ones on a 107 but you have to be a little careful as a 32/44 front results in the chain rubbing the side of the 44 in the top two gears.
I thought the Team ran the pukka WI ones with the scooped out rear side?
