New arms and a new shape for a new GENERATION.

CARBON MOUNTAIN

HOME GROWN

Made exclusively in our own carbon lab, the Girder is a home grown product from start to finish.   From initial napkin sketches, to rapid prototyping, revision after revision, exhaustive testing and certification for production.  Developed and made In-House with our own hybrid "RTM+Filimant Winding" manufacturing methods...all done by our dedicated team, all Praxis,  all for you.

ALL AROUND 

ARMS RACE

With the arm set weighing in at a svelte 488 grams, the Gen2 Girder Carbon is raising the game and ready to cause a ruckus.  For this new generation we sculpted the arm shape for improved clearance and fit on a wider variety of mountain frames.   So grab a Girder to tame the toughest courses and when the dust settles it just might be podium-time.  

TWO LEVELS |   GIRDER & GIRDER HD

THE GIRDER CARBON

Introducing the all new second generation Girder Carbon.  New arms and a new shape for a new beginning.  Take your trail riding to the next level with its wide bearing stance, massive M30 aluminum spindle, and new featherweight carbon arms with a more sculpted shape for improved frane clearance.  A fantastic upgrade for any bike and rider.

HEAVY DUTY

THE GIRDER "HD"

We get it.  You're hard on stuff.  The new Girder HD has beefed up carbon arms just for riders like you.  So, if you tend to bang into things or sometimes take the "wrong line" we highly suggest you choose the Girder HD.  

3-BOLT INTERFACE - YOU CHOOSE

DIRECT MOUNT

With all the different MTN frame types requiring different chain lines, combined with many riders preferring oval shaped rings or colors, we wanted to make things easier for you.  So we updated the Girder arms to align with the industry spacing for the common DM ring offsets.   We love our well known Wave Tech MTN rings, but we know you want choices so these arms now allow you to run other brand/type/style of 3-bolt DM ring and get the correct chain line.   Look on the backside of the G2 Girder drive side arm you’ll see a sticker showing the ring offset information for whatever ring you want.

DESIGN. BUILD. RIDE. REPEAT.   Words we live by and are at our core.

M30 BB'S FOR M30 CRANKS

BOTTOM BRACKETS

We take our bottom brackets seriously… so you know the Girder Carbon will spin silky smooth from the start.  Install it with our M30 family of BB’s.  We produce and offer M30 BB’s to fit almost every mountain frame shell spec.

M30 MTN BB's   : BSA / BB90 / BB92 / BB30 / PF30 / T47

AFTERMARKET POWER COMPATABILITY

"POWER OPTIONS..."

We know power is important, and having options is key. Thanks to the Girder Carbon’s 3-Bolt direct-mount interface, riders can easily go purchase and mount a compatable aftermarket spider-based power meter from companies like Power2Max or SRM.  Other options include power meter pedal systems from Garmin, LOOK or even meters like the VeloComp Power Pod.   Options are always good.
