I’m interested in converting my mountain bike to a fixed gear. I read that I’ll need either a track bike fork end or horizontal dropouts, whereas my bike currently has vertical dropouts. Would I need to weld a new fork end on? Would this be possible?

It is highly highly reconmended that you weld on some track dropouts like a bmx bike. It is possible to ride a fixie with vertical dropouts but that tend to lead to loose chain tension because you can’t move the rear wheel back and forth. You’ll want tight chain tension for when you go on trails or bumpy rides. The composition or material of the bike will make a differenece. If its steel then it should be easy but if it’s aluminum then I think you’re less likely to find a welder who can do aluminum properly. My suggestion would be to get a true single speed mtb frame and work up from there. Bianchi makes some great ones with their M.U.S.S and others of that line. Maybe even think about a 29er singlespeed frame. Those are designed for that specific reason and will lead to straight chainline which is a big big plus.
