cheapest way to replace Ultegra 6800 50t chainring?
After replacing my chain I've noticed it slipping on the 50t chainring. It's my own fault for commuting on it and being too lazy to replace the chain sooner. What is the cheapest way to replace it? It looks like I can get a 105 chainring for about £65. Or for another £25 just buy a complete 105 chainset... Just wanted to double check before I click buy.
