I plan on purchasing a 2010 Novara Randonee today. I was going to have them to put on a 11-34 cassette and a new rear derailleur. Do I need to have the crankset swapped out too? Specs on website lists:
Crankset: Shimano FC-R453 50/39/30
Rear Derailleur: Shimano 105, long cage
Rear Cog: SRAM PG-950 11-28, 9-Speed
If I need to swap out the crankset as well, what would you suggest?
