TDW, I’m sure it will helpful for me as well. I am still in the process of trying to figure out what I will need to complete it. I’m trying to keep the cost down, but they just keep increasing as I go along.
StuinMcCandless, when are you going to have your five-boros ride?
Right now, the biggest expense I am looking at with this upgrade is number 2. If I can just change the crank to a compact and not change the freewheel from a 9 to a 10 cog, my cost will be something I think is reasonable. If I have to change the freewheel, I will have to change the wheels, derailleurs and chain, too.
@shel the difference in 9/10 speed cranks is negligible. I ran a Shimano R700 crank for several years as 9spd and then went 10 with no problem. I did the same with a SRAM crank before that and am currently doing it on a FSA crank for the MTB.
Cranks are reasonably insensitive to the number of gears in the rear.
650c wheels fell out of favor for tri a few years ago. While this has made them a little harder to find, you might be able to track down some deals on wheels and tires in shop basements if you call around.
