For 10 years, TREE Bicycle Co has taken initiative to re-invent the wheel, so to speak. Their products look at the everyday and re-engineer them to be better. In this booklet, TREE lays out the history of their sprockets. It’s a good read too, so take some time on this one.
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!
I showed you this sprocket in February of 2011 and it’s finally seen the light of day. While I’ll always support TREE, the originators of the splined sprocket, these All-City Def Stars are looking damn fine and at $65, no one can complain. Here’s the scoop:
“Our big twist is the clocked splines which allow for weight savings, while still maintaining exceptional strength. A cutout on one side, means a spline on the other and vice versa. In addition, rather than the standard 6mm thickness, the Def Star is 8mm thick.
Basically it was made to handle whatever you can throw at it and still only weighs in at 147g for the 33t version.
We’ve been working on the design for over two years, and it’s telling that all of our original proto’s are still being ridden today. We believe that this is definitely the best sprocket on the market and invite you to check it out.
P.S. Yes we have a 28t version on the way.”
Pick one up at your LBS and check out more at All-City.
Profile has just listed up a bunch of close-outs on their newly-designed website. Head over and pick up some parts for your BMX or fixed here. I wanna see some of these finishes in the new Elite Road Hubs.
