Hi Fabian. With joy I have read your post 'SickBikeParts Right Hand Side Chain Tensioner idler wheel options. Now I want to order the Right Hand Side Tensioner from SBP and Terracycle flanged idler Wheels. However I do not understand what to buy from Terracycle. Could you please tell me what to buy with link and dimension? http://t-cycle.com/idlers-chain-management-c-41/ Thanks Jon.
