    Default Why aren't more people running 46/36 cranksets on all-road bikes?

    Is it because these bikes are used more on the road so the 50/34 is a better option?
    Is it because 46/36 is really best suited for cross with an 11x25 (or 28) cassette?

    I am always fascinated by what gears people choose especially now that road has an 11x34 option via Ultegra R8000.

    If your All-Road bike spends most of its time off-road why choose the 50/34? Are you really using that 50T on Dirt/Gravel/Trails?

    I run a 50 up front but with a 12 out back.

    34 but with a 30.

    The 46/36 went on during 'cross season and shifted very, very nicely. But I wanted more range for the roads I ride.

    And yes, Campagnolo 10 so my gearing options are limited compared you you folks in the Big S realm. And now it's been swapped for a triple 50/40/30 so I'm firing on all cylinders.

    My Indy Fab is sporting the ugly 6800 cyclocross outer ring and adapter pieces. So I have a 46/34 and it's a great setup with an 11-32 cassette.

    I really, really wish Shimano had nicer rings for this type of riding. A 50x11 bigger than a 53x12 on a road bike and it is a gear that I rarely use, especially on the gravel bike.

    The 46 outer ring lets me stay in the big ring more and the shift from the 34 to the 46 is much less drastic than from a 34 to a 50. Highly recommended.

    A buddy just picked up a Specialized with a Praxis 36/46. I think it'll be low enough for the riding we do.

    Shimano won't likely introduce rings for this because they don't really like people mixing ring sizes they say aren't optimized for their derailleurs, to which I say mine shifts perfectly. This is fugly, but very effective.

    I've got a 50/34 and 11/32 cassette. On a dirt road ride I'll use every gear, especially if it's a group ride with fast boys and girls. I'll find myself climbing in the granny, and spinning that big gear on some descents all in the same ride. On our 'usual' Tues Gravel Worlds there's some steep pitches up, and some long (for middle GA) descents. I've hit 42mph on one descent, on gravel. There's a small roller/jump near the bottom that's a little scary at those speeds! Feels like the bike is trying to jump out ahead of you as you roll onto the back side of it.

    If I'm riding solo I'm not using those fastest gears all that much, but I still spend most of my time in the big ring. Smaller chainrings would put me in the middle of the cassette more though. Our terrain is rolling, but it the 'rolls' can be dense, so even though there's not a lot of elevation change from top to bottom, you go back and forth a lot. The Tues Gravel Worlds ride is 26 miles and about 1600ft of climbing, most of which is in the first half of the route. The last half is trending downhill.

    50/34 and 11-32 here. The big gear side of the range is perfect for road and gravel here where it's flat. And the itty-bitty gear side of the range lets this flatlander climb dirt roads comfortably.

    I've gone to 46/34 on my gravel AND road bike. The 46/36 common "cross" gearing is a bit too tall at the low end for the long steep gravel grades around here (a 34x32 is just barely enough, I'm often wishing for just one more gear).

    99% of my riding is solo, so I've rarely run out of top end. And when I do coasting is just fine.

    Agree on the 50/34 and 11-32. I use the whole range. If anything I definitely find myself running out with 50-11 on big descents, which can be annoying but wouldn't give up the 34-32 for the climbs, so I live with it. Though pine for a 52 at times.

    I ran an 11-34 cassette for D2R2 this year and it was nice for the climbs but I don't care for the 13 to 11 jump at the bottom of the cassette when cooking along, the jump feels huge. I'm pretty comfortable with 50/34, 11-32 for most everything. Sometimes swap to 11-30 for the day to day.

    Here's the bike I have out in the Catskills right now: 46/34, 11-32, 28mm tubeless.



    And some action shots I just rescued from the Photobucket abyss:






    Like Justin, I spin out the 46x11 on the steepest descents. Unlike Justin, I don't wish for more gear when that happens.

    WHen I didn't have a road bike and used my CX bike for everything, I absolutely loved flying along in a 46. For my spinning style it was perfect, and I would only spin-out after about 40mph, and when on a solo ride who cares? It wouldn't be the best for a wicked-fast group ride though.

    The idea of switching out the 52/36 on my bike for a 50/34 made me depressed for about a week. I thought about going out to buy a red sports car to solve my crisis, but they were all automatic transmission. So I considered having an affair with a teenager to prop up my ego, but one of them said I reminded her of an older Woody Allen.

    So I put the 50/34 on my bike and felt better at least on the hills. As long as I am going uphill, I feel okay. Spinning out on the downhills and the double shifts required to lessen the clunky jumps between gear inches just make me feel old.

    I am considering secretly outfitting one of my bikes with a 52/42 and a 13-19 corncob for late night sessions on rollers while watching "Stars and Water Carriers" on infinite loop in order to hold myself together.

    46/36 would just make me cry.

    I run a 36/46 on the Coconino with a 11-32 cassette and 700X37mm tires. My road wheel setup (when the spacers arrive) has an 11-28 and 32mm tires. There are very few situations on the road where I'd want something higher and so far the low end has been enough. The 36-46 shift is very quick and accurate with the 8000/9100 FD. One road bike has a 34/50 and a 12-25 and the rest have standard with 12-27. The compact and 12-25 are growing on me. It's not hilly enough to have a descent where I'd need a 50-11. When I was stationed in VA Beach, I rode a standard with an 11-23 because I'd use the 11 on most group rides for the sprints. 30-40 people sprinting get near 40 mph pretty quick on a flat road with a little tailwind.
    I heart burnt bikes.

    My wife's Cannondale CAADX came with 46/36, and neither of us sees the point. With the 11-28 cassette, big square knobby 28c tires, and comparatively heavy aluminum frame that bike comes with, the low gear isn't low enough, the high gear isn't high enough, and there's too much overlap in between. This year Cannondale changed the stock chainrings on the CAADX, and now that model comes with 48/32 ...which makes a whole lot more sense to me and the missus. (And, apparently, to Cannondale also.)

    A lot of sympathy here. But you aren't riding daily training rides on that corncob? Shame, shame, shame.

    Jorn-

    When (notice how I did not say if) I move back to NYC, I'll find and build up a Cannondale 3.0 frame (circa 1988/9) with those stupid overhang dropouts using a corncob cassette and 52/42 crank. We can do laps in Central Park and fly up the Harlem Hill (all 149.54 ft of it) reliving our youth on the harshest aluminium frame ever made with the tightest gearing known to man.

    If you are really up for it, we can bitch-slap some millennials, take their fixes, and ride those too.

    While I know you weren't pointing this at me...

    My roadie is 46/34 with a 10-speed 11-23 in the rear. Gravel rig is 46/34 with an 11-25 on the road, 11-32 off-pavement. Not quite corncob, but pretty darn close.

    If you like the 36/46, you'll probaby really like the Wickwerks 34/44 combination I race CX on.

    For gravel, I'll put the 34/50 rings back on because there's usually a big downhill after the big uphill
