Can I ask if anyone knows what the max cog size will work on a 2003-ish era P3 with its stock Ultegra rear der?
Currently running 9-spd with a max cog of 27, and I have my upcoming event on the hills of Whistler.
I read many here suggesting a larger cog and/or a compact crankset for Whistler, and I see an 11-30 is available in 9-speed. I am hopeful that the 30 tooth will work, so I do not have to buy a compact crankset....
(I am mid-50s male, very avg-slow, looking to complete and not compete my first IM. My current long ride is 160 km in 6:45 with 1400m of climbing )
Many thanks for all helpful information,
