Fg Ss cogs - London Fixed-gear and Single-speed

Dylan · 12th May 2008

Why don't manufactures make hubs with splines so that a fg or ss cog can slide on it like an and 8 speed cassette does to a free-wheel hub, rather than use the thread-it-on malarkey?
Lock-ring problems would be eliminated and suicide hubs a thing of the past.
Am i missing something here coz it seems like a simple solution to a simple problem.
Flame me if i got this way waay wrong :D I only have a converted ss geared bike. I don't understand !

miche carrier cog

phasergunalex · 12th May 2008

Any cassette-type hub needs a lock-ring of some sort. However, Level have been making bolt-on cogs for a while (with their own specific hubs) and recently lodinfixiebike have been converting front shimano disc hubs; again with a bolt on specially machined cog.

Dylan · 12th May 2008

righty ho, seems like a logical thing to me.
you know, securing the cog properly.
good tho that some manufactures have seen a better way also :)

mister k · 12th May 2008

yeah, miche do something like that. still needs a lockring though.
or londonfixiebike do a sprocket that bolts onto the disc mount of a front mtb hub.

Dylan · 12th May 2008

having looked at "londonfixiebike", they do a nice conversion, has to be said. the Miche Carrier is probably the better cos it applies to current track hubs. Anyway thanks for sorting my quandary out ;)

I've got the miche carrier. It's a fucking pain because now I need a rare-as-hens-teeth Italian tool for take carrier off. Using a chainwhip the cog wont grip and always slips off, and flies across my living room.

miro_o · 12th May 2008

btw if anyone has a tool for the carrier please PM me.

:)

hammer + screwdriver!

always works for me.

lossen the lock ring a bit (so its still on the hub just a little gap) then use the chain whip to lossen it then take the lockring off and use your hands that works for me

Machining costs to move to a new splined standard would be high and the track scene is still (despite the FG freestyler explosion) is still tiny. Plus actual trackies are very traditional in their equipment use. A purely splined interface would probably develop play over time as well.

Lot of modern BMX hubs are exactly like what your describing.

Fair enough they arent Fixed, but they are singlespeed.

crank · 14th May 2008

You can get fixed trials hubs that have a splined single cog + lockring..

Think they're designed to work with a 'freewheel' in the bottom bracket.. but I don't see why you can't run them on a proper road fixed. Anyone used one?

massively.

that's why you can get £15 track hubs.

any human with a lathe can knock out a track hub shell with some threads, not so for the splinage
