I reside @ sealevel with flater terrain, but am planning a weeklong ride in colorado. I currently have a compact double 50/34 and 11-28 cassette. I did a similar ride last year and have some difficulty in the high elevation and steeper areas. I'd like to do the ride this year without struggling, but also keep the cost of components under control
I feel a 30t cassette would help a lot, but I'm unsure if it would work with a short cage ultegra 6700 RD. The 28t worked fine last year. If this would work, where could this be purchased
Another option is a mountain 2x9 crank or maybe even a triple mtn or road crank. It seems I could use the outer 2 chainring on the mtn crank or inner 2 for the road and just reuse the 28t cassette from last year. For the mountain, would I just have to lower the FD?
I'm open to any ideas.
