I have a 2004 Trek 520 that is currently set up for heavy touring. Unfortunately this year and probably next I will not be able to get the time off from work to do any long touring. So I have been looking to do more weekend rides and maybe some rando events. So instead of buying another bike, I have been thinking of doing a little tinkering to the Trek. Specifically changing the crank to either an Ultergra 6503 with 52-42-30 gears or a SRAM compact Rival 50-34. I could also use what is currently on the 520 a Sugino triple 48-36-26. On the rear I plan to switch out to a 11-28 cassette with an Ultegra GS RD. Also in order to get more trail I have a Bontrager Satellite Plus carbon fork with a rake of 50mm. Shifting will be changed to an Ultegra ST 6510. Of course I will need to get a set of long reach road calipers. Any thoughts from those with more than my limited knowledge on how this should turn out before I take the plunge?
