I have an FSA Vero Triple chainset 50 / 39 / 30 with Shimano Tiagra rear mech. I have a few basic questions about replacement:
- When should you replace? It's done about 9000 miles and some of the teeth look a bit worn. I've had the chain slip off the largest chain ring when changing from second largest - could that be due to wear or tweak needed to front mech?
- Do you have to change whole thing - cranks and all - or just the chainrings?
- Is it easy to do or easy to mess up? Is it a bike shop job?
- I've just replaced the rear cassette and chain. If I see how it goes with the chain rings would this cause issues (how much wear is too much wear!)?
Thanks, Paul.
