Excellent Service - peplacement crank arm The threads on the left crank arm of my son's Jasion Eb5 got stripped somehow & I notified Jasion & they were excellent to deal with. I was searching for a replacement arm, but they sent one with a new set of pedals for a reasonable charge (basically what another brand arm would've cost plus shipping). We took the old one off, installed the new one (& the pedals) and it's doing great again! Jasion customer service treated us right!
