Today I came across a very good deal on a Suzue Promax fixed/free quick release but I can't actually figure out why anyone would want that unless it's for a bike with an eccentric bottom bracket. Is that all it is or am I missing something? Why would a SS hub be quick release?

Its a bad idea if you ask me.

The only reason fixed gear bikes usually come with axle nuts rather than a quick release is because velodromes don't allow quick release wheels on the track. This wasn't always the case, e.g. Campagnolo Record track hubs were offered with quick releases back in the 1960s, as this catalog image shows:

Bandera

For the same reasons that a road hub of any flavor is: Positive retention with quick tool-free remove/install.

Why do so many people think a QR cam isn't strong enough to hold a single speed or fixed gear wheel in place?

Bandera

The 'modern" External cam QR mechanisms are designed for the vertical dropouts of current road bikes and are not suitable for dead-reliable use on horizontal dropouts or track ends. That being said the classic Internal cam design (see post #3) by Campagnolo and it's C&V copies by Shimano, Normandy and others are suited to FW/FG use if installed correctly.

It's not 1929 anymore, thanks to Tullio carrying a wrench to remove/install a road bike wheel is optional.

because I have slipped my nutted axle on a horizontal drop out multiple times. I wrench them pretty tight also.

Bandera

Since both axle nuts and QR cams have proven sufficient to keep the wheels of cyclists including both Merckx and Burton firmly in place on machines w/ horizontal dropouts such "slippage" as noted is no doubt due to factors other than the basic design of the retention system. Multiple occurrences might well warrant an examination of and correction of the factor(s) leading to "slippage", unless that sort of thing is acceptable and/or a good source of inter-web post-fodder.

^^ +1 If your wheel is slipping, it's due to either junk parts or user error.

People generally cannot use them on any other bikes so trying to get them to figure out the simple QR for a FG/SS bike is even harder.

I remember that massive recall over a ton of bikes and brands, not because of any actual issues occurring but because if you did something wrong that was your own fault there was a possibility of issues. I keep my QRs on the non-drive side each and every time and I certainly don't worry about them coming loose and attacking my disc brakes. I also don't worry about slippage and I have two bikes with semi-horizontal dropouts and QRs.

That is a sexy quick release.


I see no reason not to use a QR on a SS or even a fixed gear bike. Granted I have no issues with nutted axles or ones that use allen bolts and haven't planned on building any fixed gear QR wheels. However if someone made a really top end set of hubs that were QR and fixed/fixed I would probably check them out.

I've used a double-sided fixed/fixed rear hub fitted with a hollow axle and a steel, internal cam QR for a decade with no problems. It made switching from the 17T pavement cog to the 19T dirt road cog much easier.
