I bid on and bought this Shimano BB
ebay auction of bottom bracket
Was supposed to have a 107mm spindle. I was sent the same item, but with a 115mm spindle.
This is what I sent the seller:
"Received the BB-UN73 today - was advertised as a 107mm spindle length - you shipped me a 115mm. The BB you shipped is model# 1BBUN73B15,(the B15 signifying 115mm?),but I've measured it at that length, too. What's our next step? Thanks"
Today I got back his reply:
"No, that item was checked prior to shipping and the exact item as listed was sent to you.
We accept no returns"
