Mongoose Pro Class 4 Sprint Rims

These are a product I can thoroughly recommend ,although unlike other parts in this section, I doubt you will find any of these on the market today!

These are my rims and they date back to 1989 - can you believe it? They are Mongoose Pro Class 4 Sprint Rims and they are a very high-end product. They were a very limited edition release at the time, because they are the only rims that I’ve ever seen that were sold in pairs and were front and rear specific.

They are made of a very rare magnesium alloy, unlike most mass produced aluminium rims

nowadays, and in between every second spoke they have a hole punched out to save weight (10mm on front and 6mm on rear) as they are actually built for racing. Unlike other race wheels, however, they have 48 spokes due to the lightness of each rim, thus giving a strength to weight ratio better than any other wheelset on the market.

This has been proved as I have been riding them for so long and I'm not the smoothest guy out there most people didn't want to fork out £200 just for two rims but Eric Rupes' design works so well they have outlasted what other cheap wheels couldn't.

Good luck finding a pair, as I believe only 200 pairs were made with only a handful coming to the UK due to the high price.

mate,you will need to buy a reamer to,as just drilling will not get a good finish.if you really wanted to go over board  cold working the hole after will add strength to it,but that involves special equipment.
