Seriously, when I first started riding, I commuted to/from work every day (about 5 miles each way) and there are many relatively short, steep grades to overcome. When I'd hit these hills, my leg muscles would instantly fatigue, as if my life force was being sucked away. I always wondered if other cyclists had gone through something similar. My upper legs were always pretty muscular, but the muscles themselves were not especially defined. Now when I walk by the mirror in the bedroom I think out loud, "are those MY guads!?" And then my wife rolls her eyes and tells me I need to do some sit ups.

So that's what was going on...

Hi
I want hills to be as easy as possible, and am already using compact chain rings, but my rear cassette is standard shimano ultegra and has a big gear of 27. The biggest three gears come in an assembly so you can't just change the big gear individually. Is there any way that I can get 29 or 30 for my biggest gear in an Ultegra compatible arrangement. Will this have any implications for chain length etc.

Gads, if a 34/27 isn't cutting it you'd be faster carrying your bike up the hill. Are you hitting these hills with a loaded touring rig? You'd be hard pressed finding higher than 27 outside of MTB cassettes. Are you running 9spd Ultegra or 10? Otherwise, a triple chainring would give you a 30/27 arrangement, but you might need to swap out your right shifter and rear derailler to accomplish this.

Davida, IRD makes cassettes with 32 and 34 cogs, but at about $150 it might be better to just switch to a triple up front.

walking up the hill is for when your bailout gear can't get you up the hill.
which happens when you try and use 11-21 on a 53/42 on a 20% grade.
26x34 isn't enough in the snow sometimes, because of the massive amount of friction from the snow build up on your fenders
that said, for me, in flat as a board, but sometimes windy toronto area, 34x25 is low enough, even for going up short 20% grades.
actually, in toronto and surrounding areas, you can get away with a 1x# setup with 39 or 42 chainring and 11-25 cassette and never run out of low or high range gear.

I might be 5 years too late, but this thread is near the top of what Google gave me for "bailout gear". The rest seems to refer to something else entirely.

I didn't read the thread, so forgive a duplication of something said earlier.
In case it wasn't said, or the person who resurrected the thread missed it, I've always used the term "bailout gear", or "bailout granny" to refer to a granny or smaller chainring added to a bike with more typical road gearing, to provide added low gears for that unusual hill, or situation, yet keeping the overall range and combinations suited to the bulk of riding in flt or rolling terrain.
A typical "bailout granny" set up might be a 12-26 cassette, with 42-50 chainrings, and a 28t or smaller granny added. In essence it's a triple front setup that you ride like a double 99% of the time, then "bailout" to the granny when your legs say "I quit".
I use this kind of bailout gearing on my touring bike in lieu of a larger cassette because it gives me a better selection of closely spaced gears for the road, so it's geared like my 2x? road bike, but has the bailout for surprises.

I've got a 50/34 crank and a 11-32 cassette on my road bike. I consider the 32t cog my "bailout" gear reserved only for the hardest of climbs. Generally I climb in 25 or 28.
