First look: Affix singlespeed/fixed hub
This new rear hub from Affix, the convention-challenging sister company of BMX brand KHE, lets you swap between singlespeed and fixed gear with a flick of the wrist.
All you have to do is turn the large dial behind the 16T sprocket and then push it to lock it in place.
UK distributors Raleigh told BikeRadar: "This is Affix's flagship product and it basically does away with the flip-flop hub. You can change from fixed to singlespeed when you get to a hill, at traffic lights or wherever."
Made from 6061 aluminium, the 32-hole hub has sealed bearings and a 14mm hollow alloy axle. Claimed weight is 570g (1.26lb).
It's a neat idea, well executed, and it looks good, but at £169.99 we reckon you'll have to do a lot of swapping between fixed and singlespeed for it to be worth your while.

Affix stems
Also new from Affix are some neat mountain bike stems. Instead of the standard split steerer clamp arrangement, often with protruding bolts that are easy to bash your knees on, they come with a removable seatclamp-style insert.

These are available separately, so you can pick a colour to suit your bike – black, blue, purple, green or gold. This also means that if you overtighten the stem and strip the thread you only have to replace the clamp (£10.99) rather than the whole unit (£42.49).

The standard mountain bike stem is 100mm long with a seven-degree rise and comes with a choice of oversize (31.8mm) or BMX (25.4mm) bar clamp, with a black or polished finish. A beefier downhill version is also available (48mm reach), in both standard (£32.99, 250g) and CNC-machined (£42.49, 236g) forms.

Affix also make a mountain bike stem with an integrated gyro-style mechanism for hydraulic disc brakes. The Hydro Stem lets you spin your bars 360 degrees. It's available in mineral oil and DOT 4 versions, with a 50mm reach. Claimed weight is 322g, and RRP is £119.99.

By getting off the bike and fiddling with the hub... at traffic lights or the start of a hill...
This guy doesn't ride does he.

You guys are hitting the wrong nail. It's not because they ride fixed, it's because they're idiots...

Andrewjoseph I don;t think you seem to get the benefit of this hub. If the description is right then the state of the hub can easily be changed in seconds, and easily done at some lights.
The stems look real nice.

I think I understand the benefit of the hub (I don't ride fixed/singlespeed), and I'm not knocking fixie/SS riders. I'm saying the comment made by the company spokesman seems to show he doesn't understand the fixie/ss mentality.
My understanding of people who ride fixed/ss is they value reduction of complexity. This device is easier and quicker than a flipflop hub, but I don't think the people who use these flipflop hubs change them part way through a ride, depending on the terrain.
I really don't think a fixie/ss rider would want to stop at lights, or the bottom/top of a hill. get off the bike, twiddle with the gizmo and get on again.
yes it may only take a few seconds, but it seems to be anathema to fixie riders.
if I were riding fixed, i certainly wouldn't want to try changing this at the side of the road at lights.
My understanding is that flipflop hub users decide before the ride what they want to use, not during a ride. I really can't imagine them wanting to do so at lights.

I feel that the ability to change states whilst out on a ride is a good thing. It wasn't so long ago that suspension systems did not have bar mounted adjusters and required the user to dismount and 'fiddle' with it to adjust for the terrain. We forget so easily how far cycling technology has come.
Personally I don't think the hub is targeted at the super hardcore fixie rider with full tweed and deerstalker in tow, it seems a product like this (which I haven't seen before) has a broader range to single speed riders who might want to try fixed, or to the casual fixed rider who is doing it for the trend but secretly wishes he wasn't.
Simply having the option to change states whilst out on a ride without having to remove the wheel is a huge bonus, and the technology the hub brings to cycling has to be a good thing.
I don't ride fixed, but something like this would be cool and would let me try at my own pace. Also, it looks far cooler than any flip-flop hub on the market today.

Tall Rubber Duck,
I agree with most of you last post, but I still don't think changing your hub state at traffic lights is a good idea. other times out on a ride, certainly, but at traffic lights, you're asking for trouble. It seems odd that anyone would recommend doing anything at traffic lights, other than watching the lights and the traffic and being ready to move off quickly.

I commute on a Specialised Tricross Singlespeed. On the way in, it is all on road. On the way home I have the option of using the riverside track. Prefer using Fixed on tarmac and single is better for offroad, giving you the option of standing on rougher ground etc etc. This idea would be good for that, along with I have pretty much a east/west route. It is nice on a fixed, with a tailwind - with an headwind, it can be purgatory! As for the earlier comments, each to their own. They are bombproof in the winter. Fixed gear when you are used to it really is enjoyable. It also improves your roadsense, IMHO - reading the road, using the right line etc.

The convertible hub would be good for riding in very hilly or mountainous terrain, because it would allow you to freewheel down, climbing on a fixed is sweet...

"My understanding is that flipflop hub users decide before the ride what they want to use, not during a ride. I really can't imagine them wanting to do so at lights".
You all seem to have picked up on the comment about switching the hubs state at lights and that the hub goes against the "concept" of a fixie rider. True, flip flop hub users do decide before they ride and fit the wheel accordingly....but this hub takes away the need to do this, so will remove the problem of "i wont take that route because of the steep descent".........you choose what you want to wear to work, and what you wear riding, and you dress accordingly......do you think you'd still do this if you could flick a switch and change in seconds? Bad example i know, but you get my point!
This hub, in my opinion, could evolve the way fixies ride. gone are the days of removing your wheel and re-fitting the other way, simply twist the mechanism and you're away!
As for the comments about the lights....hopefully the companies spokesman wasnt talking literally - more like trying to prove how quick and simply it can be adjusted from one state to the next.
I am by no means a fixie, but, each to their own - i'm not going to come on here calling them names - same as i wouldnt to all you skinny, lycra wearing roadies!! ;) But, i've seen this hub and was quite impressed with its logic!
Rant over.

Jenine - you gear to your capabilities. If you don't mind, I will take your qualified opinion with a pinch of salt. It is on a par with your interpretation, of the English language...Muppet.
