DA 7700. Have thought about a compact for some of the more vertically-oriented stuff but have also had pretty good luck just running a 12-27 cassette. Heck, for that matter, I often through a 11-32 on my cross bike with acceptable results (even with a short cage der, believe it or not).

I run a Tru Vativ Carbon triple. It's an awesome crankset! You can't get them anymore since Sram bought them. I change out the chainrings all the time depending on what I'm doing but I typically run 30/42/56 chainrings.

The bike with gears has some kind of FSA carbon crank (can't recall the model -- whatever was out there in 2005) with 53 and 39T chainrings. That's currently paired with a 12-25 cassette, though I've used an 11-23 in the past for LD stuff, including one 1200K.

The fixie has an FSA Vigorelli crank, 175mm, with a 49T chainring and an 18T cog for the long stuff. 1/8", of course!

Shimano 105 hollowtech triple, 24-39-53. Combined w/ my "custom" 12-30 cassette, that gives me a gear range from 20-109" (semi-low recumbent w/559 drive wheel), enough to get me up any hill I've come across yet. Anything under 8% or so, I'm on the middle ring. And just for reference, I'm a very middle-of-the-pack rando.

The bike came with a Sugino 75 crankset on it. I am running it with a 44 tooth 1/8" chainring. On the back I have 15 and 16 tooth cogs on a fixed/fixed flip flop hub.

Running an Ultegra SL crank with compact rings (50/34). Cassette is also Ultegra - 12/27 which is perfect for the mountainous terrain I tend to ride.

Sounds like a great set-up. Do you use this for all your riding?

On the geared bike it's a 130mm BCD with a 50-38. The fixer is a 42. So far it's good for what's around here, but the new bike will be a small double or maybe a triple - thinking 50-44-30 with a close ration rear.

The current designee started life with a 144 BCD double. Great riding bike, but death on hills. Changed it to a 110 BCD double running 34-48. Haven't taken it on a century in the new config yet, but between the new gearing and the new tires... it's a dream to ride now.

p.s. OP, very intelligently conceived poll.

Thanks,

I've been considering an update on my Soma Double Cross. It started with a 46t & 38T 130 BCD Cyclocross double. I converted it to a 44t single with a 12-27 cassette on the back. This 1X10 combination works great within 100 miles of home, but steeper hills on century rides have been a problem.

So I'm converting the bike to a road triple. I'll soon install a road triple crankset and fenders and will begin using the bike for century rides & touring primarily. It will also have full lighting. This will allow me to complete multi-day events and tours. I'll also ride the bike year around.

I'll just need another bike for faster fitness and group rides!

Michael

That's the spirit. A separate bike for every conceivable purpose. Works for me.

Next the TT bike, then the tandem.

Tourer / cyclocross / commuter bikes = 26/42 super compact crankset.
Racing bike = 28/46 super compact crankset.
Each normally paired with a 10-speed SRAM 11-26 cassette (I have also used 12-25, 12-27, and 11-28, but I prefer the 11-26).
Typical riding: Any road that goes uphill in the Alps, the longer and harder, the better.

I mount the two chainrings on a triple crankset (I've used Shimano 105, Ultegra, and Truvativ Rouleur cranksets) using the inner (74mm BCD) and middle (130mm BCD) chainring positions. The commuter has a Salsa Crossing Guard in the outer chainring position as a barrier between pant leg and chain. On the other bikes, the outer position is empty (so special, short chainring mounting bolts are needed) - this looks a bit odd on the Shimano cranks, but looks fine with the Truvativ Rouleurs, especially when using black TA chainrings.

Hi Chris,

I could see where those combinations would be perfect in the Alps or anywhere else that has difficult climbs.

I've been using a 44t and a single chainring here in Chicago. The 1X10 gearing with a 12-27 cassette is great from 15 to 30 mph. I also use Salsa Crossing guards to keep the chain from jumping. I've used the bike for 3500 miles this year with very few limits.

Next year I'll be taking some multi-day tours and will need lower gearing for the unexpected. I'll be installing a 50-39-30 105 triple crankset next week. The planned use of the gearing includes staying on the 39t ring 95% of the time. I'll use the 50t ring above 25 mph and the 30t when climbing at speeds slower than 10 mph. I expect to use the 50t ring a few times a day but will need the 30t only a few times a month!

Most bikes should have a 48t & 34t as standard. "Super" compacts should be more available, this thread discusses this option: "Super compact" double gearing?

Michael

I tend to ride long distances (at least 600 km) on most of my bikes.

130 BCD 172.5 mm old Ultegra cranks with 50/38t chainrings on the Frezoni
135 BCD 172.5 mm old Chorus cranks with a 56t chainring on the Moulton fixed wheel
110/74 BCD 170 mm very old Sugino cranks with a half-step + 28t on the Fuji Touring bike where I've never bothered counting the chainring teeth.
110/74 BCD 170 mm modern Sugino cranks with 56/44/32t chainrings on the TSR30.

I'm looking forward to racking up a SR on the tandem and possibly a couple of other interesting bikes.
