Product Story

If your crank is the “newer” style (introduced in February of 2010) with Torx T25 chain ring screws and a thicker spider, your chainring can be replaced.

Please note: if you have an older crank with hex head chain ring screws, we do not recommend replacing your chain ring. The threading on the drive-side crank arm can become damaged and strip during re-assembly.

The bolt-pattern on these chainrings are designed specifically to fit our cranks only.

All they make you do is go to thier website and sign up for the newsletter, it takes about 30 seconds. Look at all the zits on this bike, you can bolt everything you own to this puppy, ride out into the woods, and ABANDON CIVILIZATION! Ok, that’s drastic, you could also just put a shock on it and go shred some nice trail and make it home for dinner. Tell @surlybikes what you would do with this bike in the comments and maybe it will convince them to cheat on your behalf. 🎲🎲 Nah they wouldn’t do that, would they? You have untill Friday to enter!
Oh dang, Saturday is #InternationalSingleSpeedDay Oh dang, Saturday is #InternationalSingleSpeedDay already! Y’all know the rules already, there are no rules. Get out and ride a singlespeed alone or with friends or with dogs or your pet rat or throw a local group ride like @pdxcoffeeoutside. Ride your fancy singlespeed or your mom’s beachcruiser or take the battery off your silly electronic shifting bike or ziptie your shifter so you can’t shift or ziptie your fingers together so you can’t shift?! ANYWAYS, post up whatever you get up to and tag us and use the hashtag and we’ll scientifically pick our favorite post over the weekend and send ya a little gift pack, THIS IS THE BEST HOLIDAY!⚙️🎉

But some of you are really really weird and into bike bits machined from BRASS. (*cough* @monebikes *cough*). After we made some brass Baby Groovy barrel adjusters, we decided to make a batch of brass spring adjusters. These fit any and all of our rim brakes. Maybe this is a one-time thing (they weigh literally 3 times as much as our normal aluminum spring adjusters). Maybe we’ll offer them forever (they do look pretty cool). Either way, you’re weird for even reading this much about brake spring adjusters!

Apparently the bike world is lacking in high quality reverse levers, so we dusted off the program and machined a few of these up. Yep, you can move the stainless pivot between short and long pull.
