Will be doing 6 Gap in a couple of months, 100 miles with 12k+ feet of climbing. Where I live is pancake flat so I currently run a 52/36 Praxis Zayante Carbon crankset with an 11/28 cassette (Dura Ace mechanical).
Can I run an 11/32 with the Dura Ace mechanical RD? Shimano says no but would it be ok for a one day affair as long as I don’t cross chain?
I’d like to avoid dropping $150+ on new chainrings for one day, am I good with 52/36 or should I play it safe with 50/34? (Praxis only sells chainrings in pairs)
Any other gear related tips for an event like this?
