Sram 10-33 or 10-36? Your opinion is appreciated

[deluz]

Where I live (SoCal) there is every kind of terrain from very flat to very steep.
Currently running Shimano 50/34 with 11-34 (12 speed) on one bike and 11/32 (11 speed) on the other. I don't really notice much difference between the 11-32 and 11-34 but the 32 cog is definitely smoother. At one point I tried a 46/30 crankset. I found it did not help that much, at some point you just need to improve your hill climbing so that you are comfortable on the roads you ride.
I am in that process now after being out of shape and it is long and gradual especially at my age.

On the other hand, the smallish big ring is great for those not too long climbs that you can do entirely on the "big" ring. This would be even better with a 10-36 cassette.

I`m a climber, and I think I wouldn`t miss much the 14, and would prefer two 4 teeth jumps that one big 5 teeth one.

The jump from 13 to 15 is a bigger percentage difference than the jump from 28 to 33.

Virtually identical for all practical purposes. I use a 48/13 to travel at around 28 mph. The 48/15 is good for around 24. I don't need a 14 that badly.

Not sure what you're saying, but okay.

I'm not sure I agree.

15/13 = 1.154
33/28 = 1.179

Oops, not percentages, but in terms of gear inches, 13 to 15 is bigger.

My experience has been that I am much more sensitive to gearing/effort/cadence at the speeds where I am in the 13/14/15 versus climbing when I'm switching between the 28 and 33. This is all based on riding style, and I know folks who don't mind, but that mid cassette is my sweet spot on rides so I like having more options there. It was a factor in me swapping from Shimano to SRAM with my 11speed stuff because the 11 speed SRAM stays tighter through the middle with a 16t in there. I miss it on the 12 speed, but with the smaller front ring it is less noticeable in terms of the jump than it was on 11speed.

My bike with SRAM red is my climbing bike... so at first I used the red 10-33 with a 48/35. Because I have some bumps like Mt Diablo in my immediate region I opted for the force 10-36 and I dont regret it. Now they have the RED 10-36 (E1) but I doubt I opt for that.

My other road bike has a 54/40 with a 11-34. Sustained climbing sucks with this bike.
