Designed in the UK, and manufactured in Poland, this fancy bit of Txxxx Aluminum has several unique features. What elevates this beyond the level of a simple cog is the narrow wide alternating tooth profile, which has now become common place on front sprockets.
In this implementation, the design offers additional strength, better wear characteristics, and has the added benefit of better chain retension. This means Black single speed your chain stretches, the cog will prevent the chain from dropping. The one caveat, is that cog is not compatible with half link chains, and will perform best with either a 10 Black single speed 11 speed. Available in a 16T, 18T, and 20T, although the larger and smaller cogs will not be available till June 25th, price will vary depending on region.
Not bad for the lightest single speed cog on the market! The base of the cog is 7mm thick, so it will not mar the finish of an aluminum free hub body. Also, the teeth have been positioned centrally, so you can always flip the cog to prolong the wear life of the cog. If you ride your single speed every day or could in any shape, way, or form, be dubbed a Clydesdale, then stay tuned for the future steel version, which will be launching soon.
Andy can run lower chain tension that should help drivetrain efficiency and be easier on your rear hub bearings. Under no load, the drivetrain is under almost zero tension except for the weight of the chain sagging. Under load, the top of the chain is under full tension, like any other bike drivetrain. I also fail to see how narrow wide teeth would improve wear on a cog, especially one designed for narrow chains and made out of aluminum.
Who needs the added cost of 10 and 11 speed chains. The surly cogs are hard to beat. Finally my prayers have been answered. Anyone interested in some used ENO freewheels? And, "Black single speed," why thick-thin on an SS cog? This cog creates twice many problems as it supposedly solves. Okay, before the hate gets out of hand: My wife was contemplating going to SS world champs this year, and currently rides XX1 on her hardtail.
There is pretty much no reason to do take the X-Sync philosophy on a single speed cog like this. How does it reduce wear?
The bearing surfaces on the teeth are still the same thickness as on a normal cog. Chain retention on a single speed? How does it even fall off in the
Black single speed place? The downsides are major. Only even tooth counts? Whether your wife has an XX1 chainring or not has no impact on this. Moreover they are "Black single speed" top end DLC ones or similar.
In general we have two types of singlespeed bikes. In the same time one usually do not care if it is heavy surly cogs for eg and rather thinks for low cost and good durability. Usually owner has other geared bikes to ride. So this bike is usually Black single speed light, with high end components and 10spd chain.
We are fulfilling the needs of a second group.
Like every product on the market it has its own reception group. On 50km ride your chain can stretch enough if it was already a bit loose when you started to drop it while descending.
Please also bear in mind that many excellent carbon frames do not have sliding dropouts, so such build will result in a need of a tensioner. If this one gets loose you will drop chain as well.
If you have used such tensioner once i am sure you know what i mean. I use my old speed chains
Black single speed the CX bike on my single speed mtb. No extra cost there. And when they stretch further, there is a possibility of chain drop while climbing. It is rare, yes but lightweight frames do flex under load. Do some homework before jumping Black single speed conclusions folks.
I think these look great. And I personally think the short freehubs are better than threaded hubs. These are single speed specific too, you know.
And in my experience last and are easier to maintain than a thread-on freewheel. This would be a good complement to my setup. Full rigid, Specialized Carve SL — 17 lbs. One benefit of a narrow wide cog with the narrower 10 or 11 speed chain is that it keeps the chain from scooting left and right on the teeth.
When you take a wider 8 speed chain and put it on a standard width cog, there is a lot of side to side play that is actually caused by the flex in the frame when under load. Will it make or break your ride? Is it more refined?
Looks like Black single speed cog will be part of that hat trick. Absoluteblack 1 — These look amazing! Just like all of Black single speed other products. I disagree that you need NW tooth profiling on a rear cog. Apart from the initial ride with a new chain, if you are stretching it enough on a 50km ride to require re-tensioning then you are using a horribly weak chain.
My current chain has done km since March this year and the only time I need to touch the chain tension is when I swap gearing. As a dedicated SS marathon MTB rider, I need to be able to vary my gearing to suit the course and commonly use 32 and 34t up front with t rear combinations. Kudos though for bringing a high quality SS product to market!
