What spacer (diameter) I need for my Shimano Bottom Bracket
Hi all,
What SIZE of spacer matches my Shimano BB-UN26 (BC1.37x24) 110mm bottom bracket??? I am replacing an old E-type front derailleur for a new Shimano Alivio front derailleur which will be mounted on a seatpost tube. So I guess I will need a spacer or two on a drive side. But I don't know what DIAMETER that spacer should be??? Is there inner and outer diameter? For some reason all sellers mention the thickness of spacers (1mm, 2mm, 2.5mm etc.) they sell but there is no info on diameter??? I asked them and sent them a photo of my bottom bracket but they say they don't know what spacers I need??? That's just crazy. And my bottom bracket is mounted on the bicycle so I cannot measure it. Hope you guys can help me to solve this issue. The spring is near so I want to be ready for nice weather
P.S. I wanted to attach the photo of my bottom bracket but as a new user I cannot attach a photo yet
P.P.S. I wanted to attach the URL of my bottom bracket but as a new user I cannot attach URL yet
Thank you!
