Hi all,
I currently have a Tiagra compact 50/34 chain set and a Tiagra 4600 bottom bracket cup set. The outer chain ring has sharks teeth and burring so i am guessing its time to change. The cycling shops i have queried do not have a 50t chain ring in stock so i am tempted to upgrade the chain set. What are my upgrade options?
