im interested in gettin a sparco sprint seat. but i dont know what the size is. on the site it mentions 50 cm across.. whats the typical waist size for that seat. oh and the size says M. me and a friend want to get one with sized 34-38. would we have real tight fit?

 

sit on the floor, with your hip up against the wall. Measure the distance from the wall to your other(outside) hip bone... this should be the distance across that you will need. Sounds like you may have to convert inhes to centimeters to compare that seat. My seat is 17" across, which equals 43.18cm. Hope this helps.

 

good deal. thanx man
