Middleburn Inner chainrings have been revised and updated with a new tooth profile to be 8, 9 and 10 speed compatible. These rings are designed as an inner so they have no ramps or pins.

Please Note: Middleburn HardCoat chainrings look like they show signs of wear around one of the chainring bolt sockets, this is a result of clamping during the manufacturing process and not of use. This is purely cosmetic and does not affect the performance of the chainring and will be covered by chainring bolts when installed.

As part of a cycle group I have been asked to replace the chain rings on a Thorn Tandem. I am looking at an all Middleburn Hard Coat set
as replacements to fit on the original Dotek spider.
1/ would this be a suitable choice?
2/ Is it necessary to replace the fixing bolts?
3/ are there any alternative suggestions?
SJS Customer Service:

Yes this would be a very suitable choice, Middleburn's Hardcoat chainrings are probably the best quality chainrings we've ever come across. Unless the fixing bolts have started to corrode it is not necessary to replace them. The Middleburn rings would be our top recommendation.
