I am halfway considering this:

2 speed automatic shifting hub :fruit:
High gear is 1.37X. So if I ran 32-20, high gear would be 44-20 or 35-16, No cables. And sram does warranty errythang!
NSMB KLUNKER build off
Oh yeah, I heard a rumor….
Klunker Race at the NW Cup! Combination of trail and shuttle road! I really hope they do it ProGRT weekend. Might have to get a racing license again…

We have one of those in the office. They ride well, and you can adjust the shift point.
Interesting. I had my concerns about the shred-readiness of the kick back, from an accidental shift pov. That is a bummer it broke so quickly.
A mechanic I talked to about the 3speed, had a mentally disabled 250lb customer blow one up in two months. He rides it in town, and loves to lay down fat skids. I'm curious whether he broke it under pedalling/shifting or braking. The internal 3 speeds don't really like to shift under load.
Yeah, if a klunk can't handle a drunk gorilla, it needs different parts. The Sturmey suffered what seems to be the common pawlsplosion, which I'm not surprised by considering it would sometimes get "stuck" between gears; I don't exactly know what was happening, but I could feel it in the pedals and would reset it by kicking forward and back.
The fatal flaw of that hub, however, was that the cams which engage the rollers and activate the drum brake were not big enough. I learned this after, numerous times when standing on the pedal under HARD braking, the pedal hub would clunk loudly (the cams overtaking the rollers) and leave me with ZERO brakes (72º away from the next cam, and not safe in an emergency). Hence my first ride OTB on the chunder section of Bobsled.
So, OCB has a new S2X hub that I could pick up for a reasonable price and put the guts in my hub, but I can't go on knowing that A) it's going to explode again when a sauced friend jumps on and doesn't have the owner's touch (or I happen to get too rowdy), and B) the brake might very well fail on me at the worst time, yet again.
Both the Nexus 3 or the SRAM Duomatic seem like viable options. It's only February but this thing needs to be running in time for seawall cruising within just a couple of months…
I think I might steal that suicide shifter idea. Agree 100% that housing and a shifter ruin the lines. I think I'm gonna rig up a downtube shifter on the dt bottle bosses, and just run housing from the bb shell to the hub. You don't need an indexed shifter, the detents in the hub are obvious.
Do it! I'd be stoked to see the implementation. As far as stealing the idea, DrewM brought it up as HIS idea the other day, so I'd say it's in the Creative Commons at this point…
Does anyone know what the rear end spacing should be on the Humu? Mine has been crushed to somewhere in the 115mm range.

Wow, thrown under the bus and backed over a couple of time for that slip eh? I think you were nicer with facial hair.

Thad, Andrew from Brodie is running one of those SRAM Autoshift 2-spd-hubs on his daily driver, so I'd say (sample of one) they are fairly reliable.

What about even less cable/housing: Kick shifter (in this case being used as a trailer brake lever, but whatever)… actually, on second thought - that would prevent any shifting under load situation (since your foot would be off the pedal)… but would it be hard to find the gear with a friction shifter?

But oh noes it haz geras and breaks :lol:

wow you are a ass
well not klunkers per se, I came across this old photo of my uncle and his friends in the mid 70's. figured some folks in this thread might dig it.
Just a speculative fiction. No cause for alarm.
A friend of mine has a Swobo Folsom. Fun bike.
Wrong. Always.
A little late to the party and not a classic Clunker but I'd race it pretty much as is on fire roads (different Bars). Added v-brakes using a salvaged fork brace that is ghetto rigged on there. Works just good enough.
I call it the Street Clunker

my new block-rocket:
2008? subrosa cruiser with mag wheels (heavy, flexy and don't brake for shit but oh how i wanted a set when i was a kid!). bought off craigslist today for probably more than it's worth, but it saves me dropping a mint building one up from scratch. should be a good time on the pumptrack i have in my mind's eye; already lots of fun bombing around the neighbourhood and it works great as a high speed dog walker (is how i sold the purchase to my wife)

Yeah, no coaster = no klunker. THAT'S A BMX, SON.:dizzy:
Went on a hella sick klunk yesterday, shuttled Chuckanut. Trails were GREASY!
The Walmart 29'er SHREDS! Bikes are fun, carry on.

29'er Klunk $100….could have saved myself $50! Plus tax!
