I had resigned myself to a setup with
crankset- shimano ultegra triple, modifying rings to 24-39-53
cassette- 11-28.

But it looks like there may be some new MTB cranks available in 10 speed and triples.

Key variables:
1- wide range of gear inches
2- no big jumps between gears
3- hassle free

No "consider a 'compact double'" comments please. I need a triple.

Thanks in advance for the suggestions.

This is very hard to do, verging on the mutually exclusive. It's also where triples shine.

I use the front to get overall range, and a close-ratio cassette on the back to eliminate big jumps as I ride along. I get three nice, smooth ranges this way.

An 11-28 is simply not anything I'd like to ride because the gaps are too big. I don't really like 12-27s, and use the one that came stock on my bike only when I'm going to be riding hills in excess of 10%. Mostly, I ride a 12-23 in back.

When I visited Denver two years ago, I found my regular 52/39/30 and 12-23 were perfectly adequate for in town and the foothills. I switched to a 16-27 Ultegra Juniors cassette for the only real climbing I did--Mt. Evans and the day we did South St. Vrain from Longmont up to Peak-to-Peak.

FYI: I'm running 28-42-54 x 12:27 now. The 54 is a tad too high and don't use enough to justify. The 42 would be better served with the new standard of 39. A 12:25 did not give me enough range and had to replace it. A 26 might suffice, but since changing, I figured I might as well get a little more low end. I would stay with the 12:27 if I heard reports of the 11:28 not being a good cassette.

I have a 24-42-52 on the front, 11-34 on the back. I used all of that on last week's Tour BC. Day 4 started out with a 5 kilometer climb at a consistent 10-13 percent, peaking at 15 percent: https://tourbc.net/Profiles10/TBC2010D4%20Profile.pdf .

The downhill at the end was fun: 10K of 10%. I melted the plastic rim strip and blew my rear tube twice. When I got to town I replaced it with proper Velox tape.

Three words, Jeff: Disc front brake.

HiYo: I agree with Jeff on gearing. I have a 22/35/48 front with 11-34 9spd cassette for hauling me, my 33lb bike, my 27lb trailer, and 40-50lbs of gear up whatever paved road I point it at. Have not had to walk it yet.

BTW I would have put disc brake on the rear, but my frame was not designed for it, so I went for an XTR V-brake w/Koolstop salmon pads and brake booster. Like having a 26" disc! I just have to be careful about not overheating it.

Jeff Wills

On an Easy Racer recumbent? No way- there's not enough traction. I'd like a disc rear, but that means a whole new frame.

Actually, I probably would have been OK if I hadn't been dragging the brakes to let my wife keep up. The first flat happened when I came to a stop about half way down. I came to a stop and *pssss*... the tube blew out into the rim. I knew immediately what happened, so I spent a couple minutes jury-rigging a fix. Got almost to the bottom and it did it again.

Never again will I sully my bicycles with plastic rim strips. Velox forever!

I had a plastic Michelin split over a spoke hole while using 700x20 160psi GP3000's, and put in some High Pressure (220psi) Conti's. Now I use them in lots of other wheels too.

And Jeff--you never said that you were 'laying down on the job'!

I have a 50-42-30 in front and a 12-32 in the back. If I didn't have knees that need baby'ing I would not likely need such a low gear. I have yet to need the 50 chainring over 1.5 years of riding so far; I don't try to absolutely bomb descents faster than my weight already does that for me. I can get into the low 20's on the 42t chainring which is good enough for me. I figure in another 6 months to a year, however, that I will finally have to use the the 50 to keep up with my clubmates on faster rides.
I do dislike the huge gap in gears, but I just opt to be in slightly too high a gear rather than too low if I find myself having to choose. I figure it will make me stronger
If I had a 39 instead of a 42, I would probably use it a lot less than I use my 42.

Jeff Wills

Yeah, well- 'bents are what I ride, but I've gotten over the evangelical stage. It's a bike, fer cryin' out loud! If you ride I bike, it's OK with me!

That's interesting...I'd think a rider who needs a 54 (which I don't and never will) wouldn't be looking for a triple.
I built up my Atlantis with a sugino XD triple 24-36-46 with 11-28, then switched to 12-28 because somebody gave me one. I liked it so much that when I restored a thrift shop bike as a winter project, i used the same gearing (Sugino XD was a steal from Rivendell at $110--I have about 12,000 miles on it with no trouble at all). IMO, if you're going to go with a triple, you might as well go all the way. Only reason I can see to use a 30t granny gear is if you're embarrassed to admit you can use a 24, and I'm not.

HiYoSilver

The 54 is for some downhill runs. Yeah I don't see value in a 30t low. My 28t was not low enought this weekend.

Question really is about cranksets. Should I be looking at something other than a Shimano Ultegra? Is there any other alternative, than finding an old DA triple?

Jeff Wills

The latest Ultegra triples have the lame 92mm BCD inner ring:
https://techdocs.shimano.com/media/te...9830676705.pdf
so you can't go smaller than a 30 tooth.

I've been on a quest recently for a replacement triple crank. I'm trying out a made-in-Taiwan Suntour "Superbe" crank:
https://www.srsuntour-cycling.com/ind...etail&tnid=205
which is working fine, but it's really not "Superbe" quality. I ordered it direct from Suntour USA (and they shipped it- which is kind of strange considering they're across town from me).

If I had to do it over again, I'd install a Campy Comp Triple crank:

HiYo: I have found some older XTR (110/64bcd) cranks that I can run as low as 24 'granny' on. For road bikes, a Campy Record or Chorus 102 BB works good.

Jeff: Just 'poking fun'--I have friends with 'bents' so I know the benefirs. So far, I'm too stuborn to try one.

Jeff Wills

'sall right. I've known a few people who have gotten 'bent and then gone back. Still friends, no big deal.

Those XTR 110/74 BCD cranks are the original M900 series- seriously good stuff. If I didn't have a bug in my ear about keeping a "road-ish" outer bolt circle (130 or 135mm diameter), they'd be on my short list.

badamsjr

"seriously good stuff" Yeah buddy! I was lucky enough to get one as NOS at a decent price!

My bad--I just noticed I had 110/64 instead of 110/74 (which Jeff gently pointed out).

Jeff Wills

Honestly, I didn't even notice. I guess my brain is so used to bike specs that it corrected what I read before I became conscious of it.
