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!
Look, I’m not going to sit here and say that the 44RN is the best track chainring ever but I will say that they look damn nice. Someone should convince Aaron to make more of these 144bcd 47t rings. I love mine and Chas has been riding his since he won it at Stupor Bowl. It looks damn fine on his Cinelli Mash low pro.
