Why in the fu@king hell does anyone make fixed/free hubs instead of fixed/fixed?

It makes no sense.

plenty of people make fixed fixed.
oh yeah, hey there...i know ye.

Because not everyone believes that you can run a freewheel on a fixed hub.


But to their defense, there's not much thread engagement on a Paul fixed hub for a freewheel.

because they're nice? I like mine, maybe you should try it, you just might like it.

I don't quite get this. If there's enough thread for a fixed cog, why is this not enough for a freewheel? What's the difference? why do hub makers pile on all those extra threads for a freewheel, anyway?

if youre converting an old road frame to SS you might need the extra thread the free side of the flip flop gives you for spacers to adjust chainline issues. that is all.

^^^

the freewheel body is thicker and has more threads than a fixed cog. because of the ratcheting mechanism, the teeth may not be directly over where the threads are engaged (if threading on to a fixed hub), which would create a twisting action that could (maybe maybe) tear the freehub off the threads.

not likely, but not ideal to do it either.

Because the Paul lockring is so massive you only get contact with about half of the threads on a SS freewheel.

EDIT: roadgator nailed it.

eh, i doubt it. most freewheels teeth are pretty much where a track cogs teeth would be in proportion to the flange, the teeth would most likely be engaged if the cog was screwed all the way on, hence my spacer theory.

In my experience i;ve threaded a freewheel onto a really bad POS hub and only got it about a quarter of the way on after all the spacers were set, (horrible 30 minute conversion job) and i beat the hell out of that wheel and the freewheel never budged.

Yo.


So the Paul hubs don't have enough threads. Thats one excuse. It still makes no sense for every other manufacturer to do it too.

Why the hell would you use a flip flop to convert a road frame to single speed when you could just use a road hub?

There should only be fixed/fixed.

Thank you.

just stripped out the cog on my shimano flip flop hub and now i need a new one..

WHAT SHOULD I GET??

Some muscles so that you can tighten your cog and lockring enough next time.


JK Surly is a good mix of quality and price.

I always warn people about surlys. Make sure the locknuts on the axle are tight. sometimes they leave the factory a little loose and can break after some riding.

Otherwise great hubs

This is a good example of why manufacturers continue to produce fixed/free or single sided hubs.

BTW, formula, now with fixed/fixed!

is it worth going with a phil, or am i just paying for the name?

your paying for quality as well. go here to find what you need:

the "exclusive" claim is interesting...i thought IRO used these exact same formulas?


maybe they just mean the branding is exclusive.

What I wanna know is why nobody can seem to figure out a splined hub. Or bolts, like on a disc brake.

Instead we're stuck with threads and reverse threads and stripped hubs.

EDIT: their website sucks and doesn't give much info, basically they make hubs that use bolt on cogs. You have to use proprietary cogs of course, but the two people I know who have these hubs like them.

EDIT 2: Miche makes splined cogs: https://www.miche.it/entra.html

I thought this thread would be about the Shadow 'Rant' hubs

name/bling..

im not too sure what the hell goes on with the branding of those forumlas, all i do know, is i have a low flanged set (that apparently very little of exist) that are fixed/free/branded as "formulas", and on my dp18s i have an unbranded set(but most def. formulas) which are fixed/fixed. whatever.

Phil is one of the few where there is some substance behind the name. Phil hubs are relatively cheap, compared to some other much more expensive ones, which offer about the same quality.

Why buy something with features you don't need? I have a fixed/fixed hub with 2 fixed cogs, and I am getting a fixed/free hub to run a fixed/free setup.

On the other hand, I think it's really stupid to make bikes without bottle cage bosses, and yet, some bikes don't have them. You can always NOT put a bottle cage on, so why shouldn't all bikes have them?
