i was on triples for the last 12 years
3 bikes 3 triples, 11-36 cassette. I'm oldish and never have been a strong climber no matter how svelte. But then the old thumbs start give out and wanted to try e-shifting. No e-shift triples. Now down to 2 bikes one with Di2 and the other with E-tap red. Both running 48-32 in front and 11-36 in back. Both shift perfect and almost as low as the triples were.
I would not hesitate to go to 46-30 in the front when I need lower gears. Don't care about spinning out, care about making it up the hill. Thought I would not like how the big jump in the front always forces catch up on the cassette. But with e-shifting changing gears is so fast it has turned into a non-issue.

You have to use sram or drill holes for the wiring.

I've had some very serious issues going on for the past 10 or 11 months, and when I built up the new JP Weigle I knew I was going to need some really low gears. I like bar end shifters, so the limitations of integrated shift/brake levers with respect to triples weren't a factor for me. I have a 24/34/46 Rene Herse triple mated to a 10 speed SRAM PG-1070 12-32 cassette. With 650Bx38 wheels, I have a gear range of 19.5 - 99.7" with a 27.6" as the low gear on the middle ring, and reasonable spacing between adjacent gears throughout the entire range. 12 52.0 73.7 99.7 13 48.0 68.0 92.0 14 44.6 63.1 85.4 15 41.6 58.9 79.7 17 36.7 52.0 70.4 19 32.8 46.5 62.9 22 28.4 40.2 54.4 25 25.0 35.4 47.8 28 22.3 31.6 42.7 32 19.5 27.6 37.4 As for "triples being a thing of the past" - untrue. Triples with 11 speed, probably not. Triples with STI, probably not (although I do have friends running triples with 9 speed cassettes and 9spd STI). Range like this with spacing like this and a cross-over like this with a double? Probably not. |

I'm experimenting with Campy 10 triples--this year especially, I'm having to 'postman' on the steep sections with a 39-26 or 39-29 on my go-(fairly)-fast bike. I started hoarding components last year, and will swap as I rebuild.
(Full disclosure: I turned 67 (How is that possible?) this year--but the loss of power was pretty directly attributable to some health issues (now cleared up) and a little weight gain (I've dropped 10 pounds since the spring. so going the right direction...) I rode a lot with conventional gearing (39, 40 or 42 front (in the olden days)) so I like that range of gears across the cassette--compact doesn't appeal for that reason. With a triple, I get ratios that feel right, then I can use the small front as a dump gear for when I'm struggling, and the big ring for those few occasions were I'm ripping down hill, or trying to hold pace on a gentle downhill. I inadvertently became a spinner back in the day, so I tend to ride a fairly high cadence (still) in a lower gear than the mashers. Currently working with a 50/40/30 front and a 13-26 or 13-29 rear. I'm still experimenting a little--I've got a 12-26 to try in case I need a little higher gear. I've also got a 53-42-30 stockpiled, in case i want an old school triple... I tend to get a little clinking on the inside of the big ring when on middle front/small in back on my CSi (shortish chainstays); other than that, the triple works pretty nice and setup is not too difficult. All of the older Campy 10 levers will shift a triple--except last gen Centaur/Veloce was triple OR double front, IIRC. Last edited by paredown; 08-16-2019 at 04:54 PM. |

get etap 11 for rim or hydro disc brakes
if you already have a bike you like, you need a subcompact crank, sram 11 speed 11-36 cassette, etap front d, etap wifli rear d, and shifters that match your type of brakes. no wires...and the shift logic is cool and works like a champ. Di2 does shift a bit more snapily but etap is a radically simpler system.
i just did this to my 7 year old coupled Curtlo with mid-reach calipers. what a revelation of an upgrade. the basic etap kit with derailleurs and shifters is about $1500 new. https://glorycycles.com/sram-red-eta...ke-11-spd-kit/

SRAM's 11 speed e-tap is now obsolete. Might not be smart to buy into it now. It's been replaced by 12 speed AXS. Just the shifters, and two derailleurs cost over $1600. You still need a cassette and that requires an XDR hub. You're also stuck with a large cog of no more than 33T.
I bought two Chorus 12 groups for less than the cost of one complete Force 12 AXS group. |

When you read through a thread like this, you realize that part of the attraction of e-shifting is that we're now shifting a 16 tooth difference in the front and some pretty wide gaps on the cassette (11-36, anyone?) in the back.
Amazing how fast, quiet and smooth modern indexed shifting is when you run a 50/40/30 crank and a tight 12/25 (or even 12/26) cassette. And yes, that 30/25 is lower gearing than a compact's 34/29...

Rode a Serotta CRT for a number of years with a Racing Triple 30-40-50 and 13-26. Personally, I just don’t like a triple. If there was a way to lock out the granny until I needed it I might reconsider.
Colorado travel bike now uses 34-50 and 12-32. So far so good. |

I've got a compact on my BLE with a 12-25 so it's really nice on the flats, I can find just the right gear. 34-25 is pretty low for climbing. I'm really digging the Ultegra 8000 52/36 with an 11-28. I'd rather have a 12-28 but it's still a great setup. I had a campy racing triple in the past and it shifted well, but with 11 or 12 speed, a double will cover 90% of what a triple will do.

gotta take into consideration
age, genetics, riding style, and terrain you generally ride in. If you're 30 years old, in great shape, genetically predisposed to being a good climber then this conversation is moot. if the variables are more negative than positive then you need to think about sub compacts and fat cassettes. install what you need to enjoy the riding you like to do.

The new 11-34 Campy9 12 speed is a straight block through the 17, then it's 19-22-25-29-34. With Campy's new 48/32 sub-compact crank, the 32/29 and 32/34 are both lower than a 30/25. At the low end, the new cog spacing works great. The 16T shift at the crank is no problem. Last edited by Dave; 08-16-2019 at 07:58 PM. |

My preference is for a double, 46 X 30 crankset, with a 12 X 32 cassette. High gear is around 102", low gear around 25". If I need more than 102 gear inches, I'll glad coast and watch the scenery. If you need lower gears to climb, I believe it's more than likely that a 102" high gear is plenty.
Just my opinion of course . . . |
