Hello, all!

I may be new to this forum, but have been riding bikes for about 45 years now and always learning something new.

My scenario is this: I recently purchased a triple crankset with removable chainwheels for an upgrade to the one on the bike now that has riveted ones. Same number of teeth as on the bike (26-38-48). The reasons for the change is for the ability to change chainwheels for performance as well as easy maintenance - plus not having to chuck an entire assembly in a landfill. The worn rings can be used for metal art projects. Bedides, the one on the bike has a few broken teeth as well as a few that are very worn; so getting something new is truly needed.

It is a SR Suntour XCM that I bought and the bottom bracket on the bike is currently a Shimano UN55 68x107.

My question is: Do I need to go to a 113 spindle length for a bottom bracket or will this one I have on there now be OK?
