Did you run into any concerns with chainstay clearance with the chainrings (beltrings?)? I was have looked into belt drive setups before for my commuter and have been concerned that I couldn't get a big enough gear to clear the chainstays. Is a 70+ tooth ring comparable in diameter to a normal 50T or 53T chainring?

Are there any hubs out there that could give you internal gearing, like the old Sturmey-Archers? Would be nice to have more than one gear, at least around here where it's hilly.

Could build with a Shimano alfine hub, which exist in both 8 and 11 speed. Potentially could even do the di2 version, but would need to study the dimensions of any of those very carefully.
Short answer, yes.

the seventy is friggin' huge. It's about the size of a 70t chainring would be. It's significantly bigger than any chainring I've seen on a bike. It's comically oversized, which is kinda why I went with it.

Gotcha. Thanks for the info.

If you want tall gearing, you kinda HAVE to get the 70+ rings, since the cogs don't get very small.

It's true. Also, had only a few options with gearing to get a speed I'd like. Not having horizontal dropouts limiters options some.

Could actually almost have done it even without the eccentric bottom bracket with the gearing I chose.

Lightweight parts order...

Going to pull the trigger on some lightweight parts in the next couple days.

Some WOODman Lite bottle cage bolts (in red)

Control Tech Race Light Skewers

WOOdman SL Plus seatpost (in red)

KCNC SL Singlespeed Bolts (in red)

Alligator Ilink housing.

KCNC CB9 brakes (in red)

All in all, should lose some grams while I plan a wheel build for the future.

I would love to spring for the CB10s, or CB3s even, but the price difference is pretty extreme.

I may also be swapping out the older Ultegra cranks for Red22 cranks, I'll be taking a look to figure out if I can swap bearings on the eccentric to switch from Shimano to GXP. That'd be a pretty significant weight savings, too.

Got a little antsy today. Threw the Red22 cranks on here. Looks a lot better. Now need to figure out chainring bolts, as the ones that worked on the ultegra cranks won't work on all five bolt holes. Will figure out weight savings tomorrow.

Some other light parts on the way from Fairwheel, and may be hijacking my Thomson KFC bars to move here, as well.

Thanks For Pushing The Envelope!

Hats of to you for taking on this project!

I ride vintage steel frames in a fixed gear setup with a Dura Ace 1/8 front chainring, HKK Vertex blue chain, and a EAI (Euro Asia Imports) Superstar polished stainless rear cog to give a pretty silent drivetrain. Silence you've experienced is golden....it's easier to appreciate the scenery more when you can't hear you bicycle gears whirring.

Hopefully an internally geared road bike set up much like yours is not too far off in the future.

Cheers

Silence of this bike (when it's operating perfectly) is absolutely insane. I've silently chased down (or stayed with) a few attacks on this thing a couple times. Can be quite surprising for people.

Latex Tubes & Sram Red Cranks - Weight Savings!

Threw the Red22 crankset on here, and swapped out to a set of Challenge latex tubes. Down to ~6.57kg (14.5lbs) on the nose, with a projected weight savings of another ~600g on the way with:

Thomson KFC Bars
Cannondale C1 Stem + ti bolts
slamming stem & cutting steerer
KCNC expansion plug
KCNC CB9 brakes
Woodman post (
KCNC chainring bolts
Woodman bottle cage bolts
Arundel Mandible Cages (save ~10g/)
change away from ESI bar tape, to cannondale's superlight tape (should save 100g!)
