Litespeed built up my full custom (rebadged) singlespeed mtn. bike a few months ago! Sweetest ride I've ever owned.

3/2-5 mainframe and 2" tandem rated 6/7 downtube. Purtiest welds I have EVER encountered. Issues with rear tire clearance were resolved in FIVE days total time (Arizona to Tennessee and home again). Frame was built to my specs with plenty of MY input.

I have no complaints whatsoever wit Litespeed!
