If you plan to get a Roaduno..,

[Richard Rose]

would you consider a coaster brake hub of some sort?

[P W]

Been thinking about this myself.

Probably won’t but maybe a build or two down the line…

First try will be with Paul Racers. 

Take it from there.

That would be sweet! A 3-speed coaster brake hub, no brake cables, awesome simplicity. Which I would inevitably screw up by adding a front caliper but the idea is nice! 😬

How about a 7-speed coaster brake?  I'm going to want to see the Roaduno, but...

I got this for my wife to use for shopping when we lived in Germany.
7-speed grip shift.  Front caliper brake.  The black box on the drive side handles the shifting details.
I’ve saved it for 20 years in case I want to do a coaster brake build, or even clean this up to ride.
 1. non-drive showing dropouts   2. drive side with shifting box  3. side view

Keep in mind the Roadunos are 120mm spacing. Any there any 5 or 7-speed coaster hubs that narrow?

Whups.  My shopping bike is 130mm.  Looks like I'll have to fix it rather than cannibalize it for a Roaduno.

It would be pretty easy to spread the frame by 10mm, given the longish chainstays we'reseeing on the prototypes..  Or maybe you can remove a spacer on  one or both sides of the axle, and re-dish the  wheel? 

To the original question, I've been thinking about a 3 speed / coaster brake too.  If not using caliper brakes allows for a little fatter tire, like 55 or 60mm, it will nudge  me even further that way.  

I'm watching this from a classic N+1 starting point.  I don't need a new bike - especially since I already have a Quickbeam - but was excited when the Roaduno was going to be based on the Clem.  I would definitely use a simple, low-maintenance, weather-proof, mud-proof and sand-proof, baloon-tired, cruiser sort of thing... that isnt crappy.   The ability to use 3 speed IGHs is the best thing about horizontal dropouts, once the single-speed novelty wears off.

Maybe a 2 speed kick back hub with coaster brake would make sense? No cables, simple set up.

I'm still in the 3x1 camp.  I want to see who can be the first Rivendell Customer to ride their Roaduno to the summit of Mount Diablo.  I've got a 3x1 Rivendell now and I planning  to try to ride it to the summit of Mount Diablo this Spring.  If anybody rides a coaster brake Roaduno to the summit of Mount Diablo, that would be a whole different thing.

I'd be interested to hear others' experiences -- likes, dislikes, problems -- with coaster brake wheels, ss or IGH. I've thought of a 3 speed coaster brake wheel for the Libertas that I can alternate with a fixed gear wheel as the frame has damaged cable housing guides on the tt and I don't like full housing runs to the rear brake.

I've read that coaster brakes always have some drag, but I can't say I noticed this on the last 3-speed coaster brake wheel I rode on my then 10-12 year-old daughter's Electra Townie 3i. It seemed to ride pretty well, but this was very occasionally and 10+ years ago. The Libertas has 126 mm spacing.

Has anyone considered a kickback hub for the Roaduno?

[Tangent: Current thinking about Libertas -- with Monocog replacement on hold; room for another topic, but Jones ...? --- and I "need" a fun beater to lock up outside the library and so on, is to turn build the Libertas into a stripped-down all rounder with nice-rolling 38 mm tires for outside lockup and firm-path bosque bashing.]

My dislike with a coaster brake is that the rear tire wears out a lot more quickly than I expected.

You do have to disconnect the torque arm to remove the rear wheel, but that’s usually not a big deal.  Just remember the correct screwdriver.

If I were to use a coaster brake, I'd also have a front brake of some sort, and I'd attach the torque arm with a wingnut.

Funny: my first bike build, December 1970; halfway through 10th grade (mid-summer Christmas vacation at 1*16' 59" South latitude) had first no brake at all and then a coaster brake. I did everything wrong and was disconcerted to lear that no frame-mount brake would fit, but when I got tired of riding a brakeless bike down steep, winding, narrow, 55 mph traffic arteries and in downtown traffic, I had a fundi install a flea market coaster brake. Gearing IIRC was 90" -- 50 X 15 X ~27".  Whether it was the gearing or whether the brake cam was worn out, backpedaling made little difference until you stomped backward, which would lock up the wheel. 

Indian-made rod braked roadster frame bought new and cheap from a downtown Nairobi shop, cottered crank with swaged-on chainring made for butcher's bike, Czecho steel rim and flip flop rear hub with 15 t fw and ~28 mm tire from a friend, 24" Westwood front wheel stolen from my little brother's child-scale rod braked roadster, ancient drooping aluminum drop bar, Raleigh vinyl over springs saddle, rat trap pedals with no clips nor straps. Fun times and "there's a special Providence that watches over drunks, children, and Americans." I sold it after about a year for KS/150 to fund the complete teardown and refurbishment of a ~1960 Varsity with hybrid 16/18 t AW rear wheel.
