Ha! Not saying there's no place for mamby pamby land, if that's where you wanna play, and there's been plenty of times where I wished I had a lower gear. But for most of us mere mortals with no self discipline or Jens Voigt like desire to yell at our legs, if there is a lower gear available, we tend to grab it. We are basically a weak lot and gravitate towards the easy in times of difficulty. We now have available 32 or more tooth cogs at the back, and with 12 gears, you're really not giving up anything from your 11/28 in the way of in between gears. The most versatile gearing, and arguably a lot better looking than a huge dinnerplate at the back, was when I ran a Record Triple (30/39/53) front chain ring coupled with a 12/25 at the back. I had the close ratio cassette (and only 10 cogs to boot), but a very overall wide range to work with. It was fine for any of the Alps I encountered, the biggest problem being the cleaning of three rings up front. I even had the 13/29 cassette with the long cage derailleur for a while but that was just too low a low gear, so I swapped for the mid cage using the 12/25 and just had to be careful not to cross chain with the 30 ring up front and the smallest cogs. But now I guess with the mountainization of the road bike, it's ok to have 32, or even maybe a 40 tooth cassette on back there. But it's embarrassing when the people walking alongside me are going faster. :lol:

Sorry, that survey on this thread just popped up and I realize that this gearing talk was relevant for a couple of posts a ways back, but has drifted to it's own end at this point, so we should probably let the folks get back to talking about when they're going to buy eTap AXS.

@calnago, try to climb this at mile 60 after smashing yourself (and the entire group) for the entire ride:

The average grade is deceiving as it's high teens for a lot of the climb. I was on 36/25 and my cadence dipped to 42rpm at one point. Had I been fresh, I could've done that climb at between 5 and 5.2 w/kg but 4.5w/kg was respectable given what we had done prior.

"Mamby pamby" gears have their place. The problem is that running a compact chainset would've meant that I would've probably been dropped prior to the climb because we had several over 40mph 400w efforts. I can barely tolerate the jumps in an 11-28 cassette so a larger cassette is normally off the table but would be a necessary compromise with current gearing options.

WOW - that graph is pretty damning. Sounds like the cassette is really your only option. I just can't trust AXS with the chain drops being a threat. Once that's solved then I'll have a look.

I have always used Shimano DA but on my CX bike have Sram 1x11. I have taken that bike over very rough terrain and never dropped the chain. I cannot understand how Degonkolb has a chain drop on the road. Can anyone explain how this happens?

I do not like the big gaps of 1x11 on the road and I do not like the roughness of the feel of the 1x11 at the extremes of gearing (ie biggest and littlest cog) but if the roughness could be fixed and we had 1x13 or 14 then I could be persuaded to try it for the road. Reason I would like it is no more chain suck or chain drop. But the above issue with Degonkolb makes me reconsider.

A side benefit to dinner-plate sized cassettes is that you get a better chainline when climbing, which means higher efficiency with reduced frictional losses. When in the small ring, between 7-12mph, you get a straight chainline on a large cassette. If you have a 11-28 cassette, at between 7-12mph you'll be using the three largest cogs which means sub-optimal chainline.

The strongest guys in my local club, those with FTP of 280w or more, are all running 11-32 cassettes.

2 rides with my AXS and am loving it. Other bike has 9070 DI2. Going to be hard to get me back on the old bike now.

Combo I got with the bike was 10/33 - 35/48

Murphy's Law. Most likely one in a billion occurrence.

Maybe Degenkolb is riding much harder, faster and more aggressively than you?

That's usually a pretty good answer to why pro bikes do certain things, but honestly what does leg power or cornering speed have to do with chain drop?Explain the mechanics of it... :wink:

Going on and off power aggressively (and significantly more power to call on), hitting things (bumps etc) harder and faster (much of which he might be unsighted on).

TBH, bouncing the chain off or sudden changes from full power to none at all is where i've typically had chain issues, some specific models of hub have caused more problems than others (Mavic for me, with that crappy bush).

And I can replace my chain rings on my power metered crankset. AXS owners can't.

No, they can peplace the chain rings, but they have to pay for it, as you pay for your chainrings. And BTW everytime they will get a new PM.

Or maybe, by the time these chainrings are worn out, SRAM will have changed the design again and wont have old parts so they'll force people to buy whole new cranksets? :shock: Or they're banking on the fact many people who are buying bikes at these price ranges will buy a new bike before they even wear out the chainrings.
