Here is a tool for serious cyclists. This is no wannnabe rubbing parts together to make friction trainer. This is a club level beauty with a car alternator making infinite variable and perfectly smooth resistance. No variations in resistance except by the computer controlled algorithms you set. This machine is fully adjustable to any bike size. I put my mountain bike in it a lot during the winter. There is a built in fan for the riders face/head and the bikes angle of attack is fully adjustable on the rubber mounted fork retaining clamp. This machine also has a heart rate training function that Ive never used which requires the proper sending unit. (I dont have one)

　　What you see is what you get. Clamped in the trainer is a 58cm Cannondale Aluminum/Carbon fiber CAD3 R600. In addition to the RX100 Mavic XP10 rear wheel that came with the bike I have a full set of 105 Mavic XP21s for use on the bike if you want to take it out of the trainer. I also have a 9 speed mountain bike trainer wheel with a Specialized trainer rated slick that goes with the package. This is a golden opportunity for some serious cyclist. I will not sell anything separately.
