I need to replace the crankset on my Raleigh Sojourn because I have worn out the standard one. I am 6' 7" and around 240 to 250. I was thinking about going to to 53-39 instead of my current 50-39-30. I have only used the 30 once in the 3 years that I have owned the bike, so I don't see the point in having it anymore. I was thinking about either the Shimano Tiagra or 105, but I haven't been able to find anything about how they hold up for stronger/heavier riders.
Thanks a lot!
