Hairy Posted January 12, 2011 Posted January 12, 2011 (edited) CLICK HERE FOUND: GEAR CLAMP EASILY CONVERTS STANDARD FREEHUB TO SINGLE SPEEDposted by Tyler (Editor) - January 7, 2011 - 9am UTChttp://www.bikerumor.com/wp-content/uploads/2011/01/gear-clamp-bicycle-single-speed-conversion-kit2-600x463.jpg Looking for a simple solution to convert your standard rear hub to a single speed? Sure, you could use a bunch of spacers at about 40g of weight. Or, you could use the Gear Clamp by Christopher Burdick and cut that by more than half. The pair weigh in at just 18g, but the bigger benefit is that you can precisely position the cog anywhere on the freehub body. Jump past the break for more details, pricing and photos… http://www.bikerumor.com/wp-content/uploads/2011/01/gear-clamp-bicycle-single-speed-conversion-kit1-600x428.jpg The Gear Clamp is made in the USA and costs $29.95. They’re made to be run with 16 tooth cogs and larger, but Chris says if you want to run a 15T or smaller, you’d simply put one spacer on either side of the cog, then the clamps. http://www.bikerumor.com/wp-content/uploads/2011/01/gear-clamp-bicycle-single-speed-conversion-kit3-429x600.jpg He hasn’t tested them on Campy, but like any good small manufacturer, if there’s enough demand, he can make some for Campagnolo hubs and even make other colors.

GTRacing Posted January 12, 2011 Posted January 12, 2011 Are they available locally yet? if so I would like a set.
deanbean Posted January 12, 2011 Posted January 12, 2011 Available at Singlespeed.co.za. They should be giving me a comission. Gear Clamp
EigerSA Posted January 12, 2011 Posted January 12, 2011 Really good idea that, but at R250 each? I think that's a bit heavy.
eggsovereasywithteandtoast Posted January 12, 2011 Posted January 12, 2011 Are these made of steel or aluminium.?
STEEL Niner Posted January 19, 2011 Posted January 19, 2011 (edited) Really good idea that, but at R250 each? I think that's a bit heavy.Hi Eiger,R250 is for the pair, they work a treat! Adjusting chainline and changing gears has never been easier! slide one G-clamp on, then your cog then the other GC and leave em loose. Spin the crank backwards and it basically self aligns, tighten the two clamps and you are done. To change gears simply leave the inside clamp in place. The lack of tools and time taken means it is perfect for a multi day event or quick, last minute changes.I ran them at the Atta with no issues, so i guess they are trail proven now too!Eggsover....... made from aluminium.

HeartCoppi Posted January 19, 2011 Posted January 19, 2011 (edited) The price is awfully unreasonable considering what the process is to manufacture these. If they are aluminium they are simply extruded in lengths and parted of with probably a circular saw.The cost is the extruding die and the MOQ of the extrusion..Next is drill and tap and anodise.Should be cheap.

The tolerances are spot on and minimal torque is required to tighten them up, if you don't like them, run a gear smaller than 16 or prefer to change gears with a chain whip and cassette tool you could always use plumbing pipe or simple aluminium spacers. They all work. choices, choices.....
Icycling Posted January 20, 2011 Posted January 20, 2011 I recon 2 heavy duty cable ties would be lighter cheaper and also do the trick!
EigerSA Posted January 20, 2011 Posted January 20, 2011 I've decided to order a pair since I found out they are R250 a pair, just waiting for an invoice
javadude Posted January 20, 2011 Posted January 20, 2011 I suppose you end up paying R250 for the problem it solves, and not for the actual sum of its parts. I think its a cool idea, but nothing that my current spacer kit can't solve, especially if you have one with 1mm spacers.
The_Break Posted January 20, 2011 Posted January 20, 2011 Novel. How does your free body look after removing them? Is there any damage to it where the "teeth" clamp up against the raised "splines"?
STEEL Niner Posted January 20, 2011 Posted January 20, 2011 The Break, there is no damage at all, probably because there are so many clamping faces. The advantage i have found using these is that it just makes it so much cleaner and quicker to change gears. Also getting a perfect chain line is a no-brainier especially if you have cogs of varying thickness. Just another solution but by no means the only one.I cycling, would be keen to hear how the cable ties work out, will be even cheaper than plumbing pipe. please let us know.
