SRAM PC830 7/8-Speed Chain The SRAM PC830 7/8-Speed Chain is one of the great standbys in our workshop when a bike requires a strong, reliable, smooth-shifting chain that doesn't cost too much. Made for 7 and 8-speed cassettes and freewheels. Supplied with reusable PowerLink which makes it easy (with practice) to remove and refit the chain if you favour the chain bath method of cleaning. Prelubed with GLEITMO. 114 links. SRAM chains are still made in Portugal in the same factory where the legendary Sedis chains were produced. 'An equally smooth operator on city bike paths and country trails. PowerLinkT "no weak link" technology lets you insert, press, and lock to join links. No tools needed. GLEITMOT - biking's best chain lubricant - coats chain for superior protection against friction and dirt.' SRAM.
