Re: [RBW] Re: If you plan to get a Roaduno..,

[Patrick Moore]

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.

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.

Re: [RBW] Re: If you plan to get a Roaduno..,

[Patrick Moore]

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.]

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.

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

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.

Whups.  My shopping bike is 130mm.  Looks like I'll have to fix it rather

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

[Joe Bernard]

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! 😬
