Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Is it a conversion? What crankset/BB are you using and how far off is it? If it's only a few mm, live with it.

Chances are, the spindle is a little too long for that particular crank. Pretty sure the Veulta Pista requires a 107mm spindle and you've most likely got a 110 or 113. 3mm isn't the end of the world.

If you are that worried about it, and you have road cranks (I'm not familiar with the type specified), you could space the chainring with washers. I used to do this on my old Azonic Steelhead MTN bike.

If it's just a few millimeters I'd space the ring over with washers. Cheap, painless, and it will work.

No need, rocking the post-ride sweaty afro.

Suggest a LBS spindle swap. Likely, the have more than a few in their parts bin. If they're worth their salt, and you approach them positively, they might just hook it up for you.

Get some bar tape or something while you're in there, too. Appreciation.

Mines about 3 mils off and it runs just fine. No issues.
