Two major bike shops in Moab used the Superlight as a major part of their rental fleet about 3 years ago. They spec'd them with the Vanilla R coil for more reliability and ease of service. Both shops said they got unbelieveably reliable service from those bikes. A friend of mine at one of those shops said they ran their SLs over the normal rental fleet interval time period. He said that was a mistake...not because of the SL...but because nearly everything but the frame and rear shock disintegrated around the bike. I thought that was a pretty good testimonial.
