It's been a year, last August, since my last full century. Usually neck cramps keep me down to 50-75 miles. We'll see how it goes next week.
Meanwhile I've swapping components around on the Ironman. I just found a frayed cable on the right downtube shifter last night. While I'm replacing cables I think these date back to 2018), I'm gonna swap out the Suntour GPX for Shimano Light Action friction shifters and maybe a Shimano 600 Tricolor or other Shimano RD just for giggles. I also have a Dura Ace 7-speed downtube shifter set, but I'm not sure whether it's compatible with an 8-speed 600 Tricolor RD. Guess I could find out by trying it myself.
C-Cat, I feel you on the overdoing it esp in the heat. I've been mostly no work out this week but I'm excited about the challenge of the 100 mile ride so I feel I'm ready. Still not in shape the way RT is. Man, at my current fitness level completing a (1) century is challenging enough. Shout out to RT.
I had the light action on my '86 Panasonic bitd and it worked good. Seems to me the tricolor 600 8 speed RD should work fine with the 7 speed DA shifters however I have no actual experience with that setup.
Funny I was gonna pm you and see if you got the DA 8 speed shifter and RD on the CV sales thread. BTW, I still have your tricolor group...someday I'll get it to you. I may just have to make a special trip to Fort "party' Worth.
