I agree, the disk brake from tost is a big improvement, however, the kit is for newer Ventus, my older (1984) B model, we had to do alot of reconfiguring and making shims to make it right. I really think it could have been better worked for that kind of money. A friend copied mine to put on a mini nimbus and got all of the same parts, wheel hub, caliper, master cylinder and associated parts for around 300 versus 2000 for tost
