bro

i found a couple hubs that are 120, and i found some freewheels i like... and cable stops and guides and single shifters for a 1x5 setup...

but i was wondering. im gonna use something like this probably: https://www.amazon.com/Origin8-Derail.../dp/B00629O8YM

and if the hub is quick-release i feel like that would be an issue using that derailleur hanger.

wondering if there are bolt-on 5-speed freewheel hubs in 120mm. or maybe a metal washer/tube on the qr skewer to thicken it to 10mm...


also concerned about the wheel being centered, and not offset and hitting the stays.


this is for a japanese track bike my friend wants to sell me that fits me really really well. dont try to convince me out of it, i wanna see if it'll work hahah.

please help! let me know if it will work, and recommend me hubs and derailleur options if ya can!!

thanky




....or just sell me an mkm ultimate

I'm sure there are millions of 5-speed, bolt on freewheel hubs, most of which are probably spaced at 120 mm. They came on all different kinds of low-end bikes in the 1970's and 1980's (and probably some stuff in department stores today, too).

The wheel should be centered, if not, dish it. Cyclo made a rear facing derailleur hanger in the 50s for bikes with track ends, your plan should work out alright. good luck with it and post some pictures....FWIW, if you want 5 speeds with track ends, I'd consider a IGH set up.

is there a rear brake bridge?

or

how do you attach brakes to a track frameset?

If the hub is truly 120mm (like the one below), then it won't work with a 5-speed freewheel inside dropouts spaced to 120mm -- there won't be enough room for the freewheel.



Freewheel hubs are usually about 110mm wide before adding the axle spacers needed to accommodate a freewheel. If the hubs you're talking about are ~110mm and have that extra ~10mm of spacers on the drive-side, then you should be good-to-go.

+1 to IGH. Maybe one with a brake. This SA unit looks sweet. There are plenty of road bikes with hangers, and too many people lopping hangers off to look like track bikes. I just don't like the idea of adding a derailleur to a track end.

eschlwc

^ oh, yeah, igh with a coaster brake.

forgot the name, but there's a place in portland, oregon specializing in those builds.

Grand Bois

That's a heavy steel freewheel hub with a drum brake. Not so sweet, IMO.

How about the SA X-RD3 3 speed IGH with drum brake? The OLD is 117mm.

I would normally endorse the suggestions for a 3 or 5 speed internally geared hub, but since you say...
I'll say no problem, go for it! I don't see why that Origin 8 hanger thingie shouldn't work. Almost any old freewheel hub can be respaced to the correct width. I don't think it has to be a solid axle.

DiegoFrogs

It doesn't, but that's what (s)he asked for.

I'm sure you can build any old hub into a nice wheel. If you want a bolt-on axle for a QR hub I'm sure wheels manufacturing makes one that'll work with the cones in the hub.

You can find fairly nice 120mm spaced 5speed wheels in 700c fairly easy bolted or quick release fairly easy new or used that will work for this build. Note as others have said you can not use trak Flip/flop wheels hubs for this application the hubs are wider and will not alloy 5speed and usually cant be rediished spaced to fit a five speed .The only real issue is that mounting/removing the rear wheel may be a bit akward making flate repair more time consuming.

bro

im worried about the derailleur hanger wiggling on the qr skewer cause the hole is made for axle-size like 10mm

thank you all so much. im just saying about the axle cause the derailleur hanger goes on the axle, and if it were quick release, the hole on the hanger would be bigger than the skewer. unless the axle sticks out a little farther than the dropouts..

what about this: https://www.ebay.com/itm/Sun-M13-Silv...item4d173e0470
with a vintage like suntour screw on 5-speed block and a 3/32 chain? cold set from 120 to 126 aint too crazy. i would just move it when i put the hub on, not actually try to re-set the dropouts. would a wheelset like that have the wheel/tire centerd between the chainstays?

but if you guys know any solid-axle wheels for 5 speed or any derailleur hangers with a skewer sized hole... let me knowww.

also https://janheine.wordpress.com/2013/0...cassette-hubs/

and they have nutted phil wood 120 5 speeds, but idk if theyd work with the origin 8 derailleur cause phil woods use weird nuts.

and both are kinda expensive

i just cant afford to try something and have it not work perfect first try

theres also vintage hubsets or rear hubs, but i dont really want to have wheels built. i like the velomine wheels and old n.o.s. 5-block idea, just worried about if it will be centered and not rub, or the security of the qr on the chain tensioners/derailleur hanger.. i'd need to order a longer skewer... idk. bolt on would be cool. or just a longer axle with the same inside dimensions so it would work ith the same hub just stick out like a couple mm more on either side to fit the chain tensioners/derailleur hanger.

if you know any options let me knowww. thanks for saying that they should be centered. and i know a regular 120 hub wont work, i like the ones that are mad skinny with drive side spacers. just worried where its laced that itll be dished to the side and rub my fame

when im finished i'll totally show you guys. it wont be like, super vintage but it'll be retro-style and have some vintage parts. when i finish my 531 ron kitching winter bike i'll show you guys too, cause its from '73

anyone know where to get any slightly skinnier spacers/locknuts at? so it'll fit the frame without cold setting, and stick out enough to hold the derailleur hanger? and if i make the O.L.D smaller, will the small cog/chain be too close to the frame? i only wanna make the locknuts like 3mm smaller on each side. dont know if theyd make any drive side that skinny... washers maybe??? i wanna buy the velomine wheels.. so much easier than building some. of course i'd change the skewers.

those grand bois ones are almost cool enough to just have a derailleur hanger welded on, hahah. idk how much that would cost, but i live near assenmachers... i dont know if they have a wait list or what but i know they used to build nice frames

delicious

Any bicycle co-ops or old shops around you? That's the first place I'd check for a nutted 120 spaced road hub.

bro

i got ebay, hahah. aint no co-ops. nothing super local. assenmachers shop is 12 miles away

if i can make the velomine wheel have a smaller o.l.d. by taking stuff off and re-spacing it, the axle will stick out far enough to hold the derailleur hanger. hoping i can get it centered right. and i dont want the chain to be too close to the frame. buh. i wanna do this without having to weld on a derailleur hanger. buh. i guess i wouldnt mind brazing a derailleur hanger on except i dont know how expensive that is and i dont want to ruin the paint.

do i need something like this? i heard if you dont the chain will fall off when you shift or something. ive seen 1x5s or 1xwhatevers that dont have these, like old tt bikes. is internally geared bub probably the best answer??

https://store.somafab.com/soig570rewh.html would this hub work with a friction shifter? can i cut down the super-long axle and do i need a different pulley for it? i think i'd much rather do a 5-speed block as i like that idea much more. this frame fits me perfectly, its awesome. yes, it would be worth it. i know its unnecessarily complicated.

I don't think using a quick release skewer would be a problem. The hanger in question appears to have a notch to fit in the dropout slot to keep it from moving. it also has a chain chain tensioner to aid as well.

This seems to illustrate the "notch" better:

bro

yess, just noticed they have notches. was coming back here to proclaim that discovery. this just might work. i'm gonna be so pumped. thank you!



well, i'll order the chain tug/derailleur hanger, the 126mm(it should fit) velomine wheelset, and a thread on suntour 5 speed block. i hope the tire is centered, i dont want it to be like, to the left or something and rub the frame. idk why it wouldnt be, i just dont know tons about this stuff. cant afford to make mistakes, im brooooke all the time.

then i'll need like, clamp-on chainstay cable stop/clamp-on cable guide/clamp-on single friction shifter
