    mercier kilo tt with a sugino 75?

    mercier kilo tt owners,

    I was wondering if any of you have had any compatibility issues with a mercier kilo tt frame and a Sugino 75 crank? I have currently have a Sugino bottom bracket and sugino RD messenger crank, but i have had problems with the inside of the crankarm (the area of crank that attaches to the spindle) rubbing against the outside of the bottom bracket cups, and i was wondering if this is a problem consistent with the sugino 75.

    as always, thanks.

    I have the RD in 175 and a 46t messenger ring on a 68x103 BB and have no problems at all.

    Edit: All Sugino parts.

    so are you having this issue with the RD/Messenger or are you running 75s? With the RD you need to run a 103 BB and with the 75s i believe you need 110. if you're running the BB from your RD with 75s its gonna rub of course so change to a longer spindle length BB and it should be fine.

    Also 75's are ISO taper while RD's are JIS. You should get a matching 75 or superlap BB otherwise you're going to crack your crank taper eventually.

    Not true. Is it good for the crank? No. As long as you don't go back and forth between different tapers you should be ok.

    I personally wouldn't want to do this to a $180 crank, though.

    Someone else posted about this the other day. I think the conclusion was that Suginos sometimes were too thick on the insides...I'm not sure, look over the last few pages

    Not true how? Every source I know of says that 75's are ISO. Take and ISO taper crank and shove it on a JIS taper enough times and it's gonna crack. This isn't a huge problem if you're not re-installing your cranks much but still, as you said, why risk it with a $180 crankset? You shelled out for the cranks, you might as well spend the money on a proper BB and save yourself some headaches in the future.
