TS, things are looking up here finally. Mavic cyriums are great, pretty much bullet proof. I race with a custom bike made by Rols wheels co., it's a local co.in colorado and the wheels are similar to bontrager's. Bike weighs 14.3 lbs. with the zip tubular racing wheels. Also have a TT bike made by Specialized. Love to go for a ride with you some time, maybe when we all celebrate in Vegas, Red Rock Canyon is only 30 min. from Vegas and it is gorgeous, go there in the winter to train. Regards, LMLT
