ALLEN Choose: 6mm 8mm £4.50

We've long advocated the use of decent allen keys for fix wrangling. Now we've switched suppliers to bring you these budget Eldis from the former East Germany. The shafts are long for good leverage, and both sizes have dense plastic handles which make it less painful to wrack up the torque. 6mm is the most common size on bolt-on hubs, while the 8mm will come in handy if you're switching spacers on a LeVeL hub. Or assembling Ikea furniture. (We're not fussed.)

	COMBI 1/8 £25.00

This is the TL-SR-22, the new version of the Dura-Ace trackie tool. Like its predecessor, it combines a 1/8 chainwhip with a lockring spanner. Unlike its predecessor, it's made of hardened steel. The spanner is a bit small for BB lockrings -- check out the Hozan tool if you need to shift larger 'rings. Restocking shortly.

	CRAK! 1/8 tool £15.50

We originally bought in the Cracker when we discovered the Interlock chain's tendency to giggle nastily at Park tools and Topeaks and the like. But then regulars started asking for crackers of their own, and we realised that a bunch of people out there need something fairly substantial for wrangling 1/8 track chain. This is a semi-pro tool with some neat features like a replaceable rivetpopper (one spare incl.) and a limiter collar that stops you pushing the rivet all the way out of the link. Take no crap from your Izumi!

	HOZAN 2 ends £21.50

The Hozan C-205 lockring spanner is a dedicated tool, cold-forged and tough as old boots. The double-ended design provides excellent engagement on most lockrings, the 10" handle gives good leverage, and it's still light enough to backpack if you think you might need to change cogs on the road. If you need a shop tool and don't mind considerable weight, we can source Hozan's unstoppable lockring plier on custom order.

	PEANUT Choose: 15mm 14mm £4.50

We just managed to restock the Cobra 'peanut butter' spanner in both 14 and 15mm varieties. The 14mm version is a bit slicker, having those blue plastic grip things, tho' both are pretty rough by contemporary standards. Nevertheless, handy if you find yourself wrangling axle nuts.

	CHAIN Choose: Silver Black £24.50

The Interlock chain is made up of halflinks. There are no 'inner' or 'outer' links: each link has a bottleneck shape which interlocks with the links before and after it. Shadow reckon that this tends to even out the load on the pins and so increase useful life, which sounds reasonable enough. But for fixers, the design has another advantage: it makes it extremely easy to put the rear axle exactly where you want it in the dropouts. In fact, if you're into magic gear setups, this chain may be the answer to your prayers. It's only available in 1/8", and, being designed for BMXers, it's on the short side. Probably won't stretch to a really large ring. If in doubt, drop us a note.

	CHAIN Bushy £31.00

People used to ask when we would be getting in a proper NJS track chain. I mean, they'd pester us every day in the street. We've always brought over HKKs and Izumis on custom order but Izumi are expensive and can be noisy and HKK aren't officially exported any more. Then our distributor sent us some of the new DID chains. DID are Big In Japan but haven't been seen much in Europe in the last decade. That's a shame, because this is a really nice retro track chain in bright silver, with lovely big smooth-running bushings and the NJS logo stamped on every link. 106 links, so long enough for most applications. 1/8" only, natch. Restocking shortly.

	SCREWY 1/2 of 1/8 £4.50

The Izumi halflink is one of those odd products that you don't know you need until you've tried it, at which point it becomes indispensable. It's a halflink for 1/8 chain, which makes it a useful object for getting your rear wheel optimally far forward and so on. But also it's a screw-fastened masterlink, meaning that you can demount the chain in seconds using a screwdriver and a set of needlenose pliers. The link was developed for track use, so we recommend regular checks and the use of Loctite if you're planning to take it on the road.

	1/2LINK Choose: 1/8 3/32 £2.00

We're now stocking a common-or-garden halflink, the Gusset Slink. (Some of you will recognise Gusset as the name of ID's own-brand line of BMX parts.) This is a nice solid part, available in 1/8 or 3/32, and cheap. All fixers find halflinks useful from time to time, but they really come into their own in so-called 'magic gear' setups on bikes with vertical dropouts.

5x BOLTS £5.00

EAI single chainring bolts are what you need to install a 1/8" or 3/32" single chainring on a double or triple crank -- or a track chainset, come to that. These aren't in any way exciting, being made decently enough in nickel steel, with an allen bolt fitting one side and a slot the other. It is still stupidly hard to find single chainring bolts in the UK, and these do the job pretty well. We sell tons.

HACK Choose: 0.6mm 1.2mm 2.0mm £3.75

You don't need chainring spacers. Your chainline is perfect. However, let's pretend, just for a second, that you have this... friend whose chainline isn't quite right. If your friend puts a set of these between ring and spider, they can move their ring a little, hopefully enough to shift it into the plane of the cog and correct the misalignment that's bothering you, ahem, them... Sets of five.

	WOODY £6.00

Cork grips were common a century ago, but lost ground to rubber and plastic. A minority of riders have always sought them out: although less pliable than rubber, they are comfortable, and don't get sweaty. If you like summer riding without gloves, they may well suit you. These modern versions are produced by Nori-San for flat bars, but you could probably mount them on drops at a pinch. Restocking shortly.

	RUBBERY Choose: Black Grey Natural White £6.00

Oury grips were designed for MTB riders, but have become popular among messengers for their combination of thick rubber and low price. We usually have limited stock in black, grey and natural, the last being a kind of translucent white colour, like a lightbulb. Restocked. We couldn't get any of the new 'luminous' type this time out, so we got some plain opaque whites instead.

	STICKY £3.00

80ml of finest Maruni rubber cement in a little tin. Smells great.

	V. TALL Choose: 80, silver £18.00

It may not look particularly impressive, but the Delta is the only 45° A-head stem on the UK market. (SystemX has a 40° model, but the Delta has a cm less reach, which might make all the difference.) Why are we so excited to be stocking a comfort bike stem with a two-bolt clamp? Well, a lot of you have Nitto B-135s or On-One Midges on your MTBs, and you're likely finding your bars too low and too far forward. We're now down to 80mm, silver. The main stock is 25.4mm clamp -- contact us for info on the scarce oversize versions. Last few.

	LOCKRING Matt £5.50

Dura-Ace lockrings are the ones we sell most of. They fit our Kogswell and ENO hubs (and other people's Sugino, Shimano, and Dura-Ace); they're very tough; and they bear the NJS stamp. If you aren't sure which lockring you need, this is likely the one -- but feel free to ask. Restocked.

	LOCKRING .alt £9.50

You just had to be different, didn't you? Sugino lockrings fit Kogswell and ENO hubs, bear the NJS stamp yadda yadda, and they have the lettering in contrasting yellow-on-black.

	LOCKRING Shiny £8.00

EuroAsia lockrings will fit most Campagnolo hubs and compatibles, but they're a good bit cheaper than the Campy versions (which are available on custom order).

	LOCKRING Gallic £5.00

Bringing up the rear of our quartet are these Miche lockrings. They work with the (now rather obscure) French threading, meaning compatibility with Miche and Mavic hubs plus some other vintage offerings.

	ENDS £10.50

OK, here's the pitch. You have a nice old 70s frame that just wants some track ends. You've found a local framebuilder, but the phonecall was inconclusive--he's tracking down carbon wishbones, doesn't know where he'd source track ends. Impasse? Nope--get your own set from Hubjub, and hunt the builder down to his local hostelry. Buy him a pint. When you put his drink on the table, drop the track ends right next to it. Ask casually when he can put them on? Result! We have various sets in stock. Primary choice is these simple Tecnociclos, as used by Mercian. Email for more on the others.

	NUTS, R Shimano £10.50

Tracknuts are heavy-duty nuts with a captive washer. This setup allows you to exert maximum force on the nut without fouling it against the dropout. Tracknuts are less common than they used to be. Most of our hubs use modern allen key fittings, and the one exception ships with very nice tracknuts as standard. But if you have an older hub with a threaded axle, tracknuts are a must. Ours are Shimano Dura-Ace, and they're seriously good. Restocked.

	NUTS, F Shimano £10.50

We do the matching fronts, too. USP is that these take the same size spanner as the rears, despite being threaded for a smaller axle. Simples!

	NO FEAR Choose: Full Monty FrontQR Seatpost £55/£27/£27

Pitlock is clever security kit from Germany. You know how often you see bikes on the street missing front wheels, saddles, or bars? The Pitlock system goes a long way to eliminating that. It should be of interest to any cyclist, but we're particularly interested in getting the news out to couriers and tourists. Click the 'Tell Me More' link at left to find out more about the system and the various kits we offer, plus the extras like dedicated clamps, saddle loops, and 1" Aheadset caps. Fully restocked. Sorry about the price increase -- it's the Euro...

NO CHIPS FiveGold £26.00

We just had to show you this packet. The Kashimax FiveGold is a cylindrical ring of medium hard clear plastic with an aluminium inset. It's designed to clip around your top tube at the point where swinging bar ends would otherwise damage the paintwork. The FiveGold is one of those highly-specialized items that either thrillingly sorts you out or totally passes you by. Over to you... Restocked.

	IRON-ON Choose: Oval, black £50.00

If you ride your track iron home from the velodrome, Dia-Compe's clamp-on brake might be the answer to your prayers. It's a simple dual pivot unit equipped with special mounts so that you can temporarily attach it to your track fork without drilling, and it comes with a lever and a pre-cut cable to make installation as painless as possible. The unit is available in 'oval' and 'round' versions to match your fork legs and in silver or black. It rides OK. Within limits. If you've ever ridden a drilled track fork, you'll be aware that it tends to judder under braking forces. The Dia-Compe is certainly an improvement, tho' it's not a definitive solution. But we reckon that most potential buyers will be doing their actual braking by other means. The Dia-Compe will keep you street-legal in the UK and likely in other EU countries as well. Presently only black, oval.
