Appreciate the feedback thx guys...I’ve had to google some of acronyms below but also learned in the process???? thx. I have both sets of chainrings 53/39 and 52/36(currently using) and using with 11/28. I rode 53/39 and 13-26 Campy for about 6 years did one Double Century with it and sweared that I’ll never ride those gears at DC again????????♂️. It was my first DC two years ago...Changed to Ultegra, bought it second hand with 53/39 but changed the chainrings to 52/36 for my second DC last year...a much fitter me enjoyed the race and improved my time....I think I have gotten used to the 39t chainring for climbing as the 36t just feels a little bit too light (maybe also psychologically)....even if I gear down* on cassette. So just playing around to see if the 39t will work better for me... don’t really need the 53t ring as the 11 works fine with my 52t... Don’t have the tools etc. to chop and change so I have to take it the the bike shop to have it changed... Appreciate all the feedback????????
