One of the main requests AARN receives from his track chainrings is a 51t track ring. Well, guess what? They’re in stock now. Head over to AARN to swoop one up.

I’ve been using SRAM’s own direct mount ring for a few weeks now and love it. While I’m all for the slick black aesthetic of their native design, it’s hard to deny the appeal of stainless. Wolf Tooth Components just launched a super durable, SRAM-compatible, made in the USA direct mount chainring for your 1x system. Head over to Wolf Tooth Components for more information and availability.

Unfortunately, in the time this post was scheduled, all that remains are the 24t rings, so if you’re looking for that size, you’re in luck. If not, you’ll have to wait for a restock…

AARN’s 144#N track chainrings have returned in the AAMERICA anodizing, although this time, they’re black, silver, and gray. Each ring’s finish is hand-applied, meaning each part is unique, and is packaged in a limited edition letterpress printed envelope with a black to silver split-fountain logo fade. These ring are available in 47 and 49t options, with only 100 units in stock.

The Radavist’s readers can use the code “AAMERICA” for 12% off their order of anything in the AARN webshop, including these new rings.

The AARN chainrings were an instant classic when they launched back in 2011. Each year, designer Aaron Panone restocks the 144#47/49 chainrings in limited batches. The first restock of 2015 is now on 44RN, in a run of 200. Head over now to pick one up.

With the development of the narrow wide chainring, more and more companies are beginning to roll out their own designs for MTB and cross bikes. The newest I’ve come across is Endless, out of Asheville, NC. They machine and anodize everything in the USA and while they currently only offer 104 BCD rings, they do come in an array of colors for 32t or 36t rings.

See more at Endless.

AARN just restocked the 144#47 and 144#49 track chainrings at his web shop. These are some of the best track chainrings on the market and the demand is always high, so head over now if you’ve missed out before.

Another player in the game that is narrow wide chainrings is Praxis Works. Their new MTB Narrow Wide 1x MTB rings are now in stock in 32t – 38t for $50.

These things are always in high demand and it’s only by some miracle that they’re not gone yet. AARN has a select few silver 144#47/49 chainrings in stock over at his web shop. Swoop em up now for $88 a piece.

When Aaron and I first talked about doing something crazy for his “final” run of the popular 144# track chainrings, we decided on a red and blue splatter anodizing. These had to drop at NAHBS and the timing worked out perfectly.

Available now, in 144BCD 43t, 47t and 49t exclusively at the AARN Webshop. Swoop now because these won’t last!

The guys at Factory 5 in Shanghai just launched their newest product, the Lattice chainring:

“The Lattice Chainring is one of our proudest moments in F5 history. We went back to the drawing board with this one and came up with something technically innovative and intrinsically beautiful. In other words, it’s freaking light and euphemistically gorgeous.

Precision CNC milled from a single piece of 7075 aluminum, the dual-plane cutouts maintain strength whilst reducing the chainring’s weight to a mere 78g. We’ve radially brushed the ring and had them deep anodized to give the industrial feel we strive for at F5… and the result is something we’re chuffed to say is made in China.

It comes in 144BCD, Black, Slate and Silver, 47, 48 and 49T.”‘

I’m stoked on these! Pick one up here!

One of the reasons why I’m going XX1 on my new Rosko mountain bike is the simplicity of running a single ring up front. When you lose the front derailleur, it lightens the bike up, while freeing up your trigger location for a dropper post or front fork control. XX1 runs a 32 or 34 up front and up to a 42t cog in the back, which is an incredibly wide range.

But what if I want to run a single ring up front with my XT setup? Before, you’d have to have a chain keep, which isn’t an issue, but it certainly doesn’t look as sharp without anything holding your chain to the ring. One of the first things I noticed on Tim’s Yeti SB95c that I rode was the Wolf Tooth Components 30t 104BCD ring.

Aaron Panone of 44RN has been working on a new 130 BCD chainring, meant for 1×10 drivetrains or single speeds. These are still an early prototype, exclusively for Tomii Cycles but expect more details to come.

Aaron and I are going to be working on more products in 2013 and these photos just got me very excited for new things to come. See more at the Tomii Cycles Flickr.

Back when I did the Raidô contest, Aaron at 44RN made a few of these purple anodized 44RN 144#47 chainrings. I’ve been holding onto mine for well over a year, waiting on the perfect project to put it on. Over the past few months, I’ve been slowly acquiring parts for a new track bike build, more to come!

A few notes about the 144#47 track chain rings by 44RN. These rings are designed to be extremely quiet, right out of the packaging but there are a few things you need to do:

-run a new chain
-run a new cog

Check out why below.

Finally! As the second installment of the Purple Projects, I’ve teamed up with 44RN on another run of his 144#47 track chainrings. Machined in Boston, designed at 44RN, in Somerville, these rings have been put through the ringer for months. Pick up a silver or a black now in the PiNP Web Shop.

I put this up on my Tumblr, meaning to schedule it for a week from now, only to have it go live today, sending a slew of emails my way. It is true, 44RN is machining a new batch of 144#47 chainrings this week. That means another week or so for anodizing. As it stands, there will be 50 silver and 50 black rings in my web shop around Halloween.

This is only to alert you that you should set money aside for one. As far as I know, they’ll be $77, the same as before. Aaron is a very talented designer and he is doing this out of the goodness of his heart. He’s not making much money here, and it’s only after constant pestering that I convinced him to do this.

Everyone who’s had these rings (myself included) has nothing but positive things to say about them. So get stoked!
