It would be a lot, LOT easier to machine a Shimano spline straight onto the hub shell - that way you wouldn't be stuck with some proprietary design only available from one company. Then, you could use one of those nice Boone Ti cogs

familyman

Well then Mr. Thylacine, I do believe you've found your niche. You've got to know people with the machining capability and you certaily have the design capability. I only have to ask, can you go use that pattern on your stuff or will Shimano try to sue you for using a propritary pattern without permission. If you can use it then go for it. It's not rocket science, it'll give you a new project, and I'll buy one of the first batch.

I'm not sure if this is off topic, I just read the forum for the great info, but from my history in bmx I do know that there are freecoasting hubs that have a backpedal mechanism that locks them much like backpedaling on a fixie would, I have known a few people who rode flatland with them in my time.....maybe his problem pertains to a similar hub??

Thylacine

Sure, I'll just add it to the bottom of the list here of "Cool things I'd like to make and sell".

familyman

Hey Mike, how you and Debbie and the baby doing? Fancy seeing you here. Freecoasters are way different, we don't want to coast at all here, that's the key.
I still want Thylacine to get off his ass and do some actual design work. Lazy aussies.

i just thought of another option. you can get those .125" thick cassette cogs, weld a splined freehub body so it won't spin any longer, and position the cog where you need it with spacers on the cassette.... viola. a fixed splined cog. xcutterx and i did it on my roommate's fixie. the idea was suggested by a track rider who had a tt 8 speed zipp disc that he wanted to use on the track.

pitboss

thanks for grabbing that one

Thylacine

So you managed to weld Steel to Aluminium eh? You're a freakin' genius.

Okay, so you just 'froze' the freehub by welding it solid, is that what you're saying?

skitbraviking

looks sweet to me, too. I too would also be concerned with it's ability to work with other parts, cogs, freewheels, lock rings, etc.

ephemeralskin

that anecdote about the bike messenger is odd. how frequently would anyone need to change their sprockets out, or otherwise 'service' the hub? its like what-- they get a heavy load of mail and are like 'shhit its time to switch to the 18t again, good thing i dont have to go to the shop now that i have my new LeVel hub!'

Hello,
I would be glad to answer any questions you have about the Level Components InI hub. I ride one every day, I work on one as a messenger
My bike set up,

Gunnar Street Dog, Level Hubs front and rear, Thompson seatpost and stem, No brakes, Velocity DeepV rims or Mavic CXP33s. Phil Wood BB, Campy track cranks.

Q: How has it held up to a year of working as a bike messenger?

A: Outstanding. The fit and finish of the hub is wonderfull. The higher flange gives you a nice tight wheel. There is nothing to strip.

Q: I've never stripped a cog, why should I buy a more expensive hub.

A: After you pay for Var lock ring plyers, a lock ring, a cog, and a chain whip you could have two level hubs. and never worry that your going to strip out. Fixed gear MTB riding tends to strip more hubs then road riding.

Q: Does the cog allow you to alter the chain line?

A: Yes. The cog allows you to adjust your chain line for a much closer fit then a threaded system.

fixed4life

As to changing cogs during work, I do not do that. However after work I sometimes change a cog for the ride home. I also change if the day is really windy, or I am tired.

fixed4life

I am not sure how using a shimano cassette type lockring continues with the idea of not using a threaded cog. A shimano cassette is held onto the cassette body by using a threaded lockring cog. If you used a regular cog from a shimano cassette how would you hold it onto the hub? If you wanted to run 1/8" chains and cogs what would you do?

shecky

I suppose a steel hub would be much less prone to stripping than aluminum.

gally99

the miche setup doesn't keep you from stripping a hub at all (in my case actually it made it worse)
it still threads on like normal, then the cog fits on to the threaded part...
i had a loose lock ring and at one point it slipped, the cog fell off the base part, wedged itself between the base part and the lock ring, and completely stripped the part of the hub that the lock ring threads onto...

also, i think i saw it on these boards (maybe not) but somebody is making cogs that bolt on to a disk-brake hub, where you would normally attach the disk...

Has anyone seen the new IRO SS hubs with a integrated freewheel made for Shimano cogs? https://www.irocycle.com/fixedgearand...inc/id115.html

I would love to see these without the freewheel.

jerrryhazard

Noticed this as well. The cog is still being secured to the hub by threads, not fixed splines. The benefit for ease of cog changing is apparent, but it does not really address stripping threads...

There was photo a few posts up (#23) of a cog that is bolted to the hub. That seems reasonable... ?

CoppellStereo

a lot of observed trials hubs are fixed in the rear for a front free wheel. there are plenty of brands out there that make these hubs, and there is also a kit to turn a normal hub into a fixed gear hub

A problem I've heard addressed in another thread is that play can develop in the splines of Miche cogs. I don't know if this happens regularly when people skip and skid with them on the street, but it happened to someone on the forum a ways back. They are most likely geared (no pun intended) toward track use, as I've heard Miche hubs to be, rather than street (ab)use.

gally99

i personally never had that problem riding the miche for quite a while on the street, with a heavy gearing (50-14) and brakeless...
that said i still think they're pretty useless for the street...

A trials hub is only fixed gear when the freewheel is built into the crank asembly. This is not a fixed gear bike, but a way to move the derailur out of the way. The disk rotor bolt on idea is not bad, but it should limit cog size, hub spacing, and depending on the design of the cog, not nearly as strong as the InI. Non of these problems exist with my Level hub. I think they will have a bolt on for disks soon. They mentioned a bolt on disk adaptor. I run a disk hub SS on my MTB. Can't wait for that. Just started fixed MTB riding, and it turned my old trail into a whole new beast.

ryan_c

Sorry, I didn't mean to imply that this was a common problem or anything - I had just heard of one single instance of it. I am following this up b/c I don't want to scare off future readers of this thread from the hardware if it's good equipment w/ a fluke failure.

jitensha!

sliding off the subject a bit, their track hub is pretty swank: https://www.woodmancomponents.com/pro...track_rzn.html
