I don't know how long you've been riding but I still remember the days (1997) when I rode the Terrible Two double century (lots of steep climbs) on a 53-39 and 11-27. And my first tandem was a custom racing Santana that had double chainrings (55-42) and a 11-26 cassette. I went over some steep hills with no bailout gears. Twenty years ago there were no such things as a 36 or 40 :D I didn't convert to compact rings until 2007. So what gears did heavy cyclists use twenty years ago :wink:

I have been riding for about 20 years. When I was 170 lbs, I could climb mountains on a 53-39 / 11-25 combo. I am not 170 lbs anymore, and also do not see the point in killing my knees. Just because we did something back then doesn't mean it was a good idea :)

20 years ago. Funny, but that is recent. 20 years ago people used triples. Dura Ace had a triple crankset in the 1990s. Not sure about Record. Then the compact euphoria came along. People in the truly olden times used triple cranksets. Way back when the exact same shifters and maybe derailleurs shifted everything. No need for new parts. Today to get a triple you need new crank, new derailleurs and new shifters. Expensive. Probably why the compact craze is so popular. Cheap for bike companies to use compact cranks because everything is identical except the crank.

Why not get a miche cassette they do these sort of ratio's cost you less as well.

Finally did some long climbs on a 12 30t miche cassette. 12 13 14 15 16 17 19 21 24 27 30T. I use 41t inner ring on this bike and 20+% gradients are fine but i am a bit lighter than the last poster.

These 11-36 / 40 shimano cassettes sound interesting. What models are they and what shifters / derailleurs do you use? Thanks

On one bike, I have Ultegra mid-cage RD + Wolftooth Roadlink + Shimano XT 11-40 cassette with a compact (50-34) crankset. On another, I have a 105 mid cage RD + SRAM 1170 11-36 cassette with a compact crankset. Both work fine in all combinations on the stand, though I try not to use the big big combo on the road. Here is what the 11-40 combo looks like:

Looks good. Are the Shimano MTB cassettes compatible with road shifters? What shifters do you use?

If you use an xt m8000 or an xtr m9000 rear mechs you wont need a road link but you will need a jtek shiftmate to convert the cable pull. Also if you have di2 the mtb rear mechs they will work with 11 speed road shifters.

Mtb 11 speed cassettes will work on a 10 speed hub allowing you to use old dura ace or ultegra hubs.
