lambretta_ash I have a 1978 Alpina 350 Black in the photo my play bike. I also have a 1972 Alsherpa 250 its a tricked out Alpina that someone with a great more experience than myself did. It has a home made Sammy Miller conversion to the frame, Sherpa T triple clamps, forks, rims and hubs. 11 tooth front and 46 in the rear. I will proably go to a 50 tooth some day.

Where do you guys get your tubes from? and what kind do you use for trials. Im having trouble finding 2.75 x 21" Ultra Heavy duty Michelin 4mm tubes in the USA. Thanks Keith

Thanks I will try these .

I have a 1972 Model 85 and 1978 M213 Bultaco Alpinas Im looking to gear down to ride trials events MAVT. Does anyone know where I can get a 57 tooth rear sprocket ? Thanks
