Bitter SRD metal & alloy full-suspension German mountain bikes
These two Bitter mountain bikes mark the official debut of SRD – Bitter Racing Growth. These are the Homebrew undertaking bikes Bitter created for their very own workforce and their athletes. Ever since Bitter introduced all of their manufacturing from Taiwan again to Germany, they knew decreased lead occasions and shorter growth cycles meant they may tackle extra enjoyable new initiatives.
The oldsters at Bitter experience a whole lot of mountain bikes. And one of many first issues they did constructing bikes in Germany, was begin tinkering with full-suspension bikes. I truly noticed the first linkage-driven single-pivot Double Choc nearly 4 years in the past.
(Secret insider bike rumor… a less complicated, lower-cost single pivot MTB undertaking continues to be growing within the background of Bitter’s workshop, from what we hear.) However it takes a very long time to excellent even a traditional design, so now Bitter are hyped to supply their first two full-suspension mountain bikes to the lots.
Nicely, a small mass. The 2 SRD bikes can be found to the general public in tremendous restricted version batches a couple of occasions a yr. All, fully made in Germany, at fairly affordable costs – in contrast say to a carbon frameset or one thing unique in metallic like an Atherton or Frameworks body.
Bitter SRD Cowboy Cookie vs. Double Choc
The Bitter SRD Cowboy Cookie is a 120mm XC to Downcountry bike prepared for journey, paired to 120-130mm forks. And the SRD Double Choc is a full-on Path bike with both 136mm or 148mm of rear wheel journey relying on totally different rockers, and 140-160mm of journey up entrance.
Each share the identical traditional Horst-link 4-bar suspension design – in reality, solely the entrance triangles are totally different between these two new mountain bikes. They each function a flip-chip on the decrease shock mount that lets riders tweak their geometry: +/- 0.3° on the headtube & +/-5mm in backside bracket top.
They usually’re each fully made-in-Germany.
Manufacturing & materials particulars
The Cowboy Cookie and Double Choc each match Bitter-welded metal mainframes to Actofive-machined seatstays & rockers, actually CNC-machined 600m down the road from Bitter HQ. It’s possible you’ll discover the similarity with Actofive’s personal short-travel I-Practice which was developed alongside this SRD undertaking with Bitter.
All of those prototypes we see right here had chainstays welded by Nicolai. However Bitter have their very own welded 6061 swingarm within the works now too, which can be prepared for this primary spherical of manufacturing bikes. Bitter have been simply anxious to get the brand new SRD mountain bikes out to riders as quickly as attainable, so we haven’t seen the brand new rear simply but. Finally, we hear there can be Bitter’s personal seatstays too, to assist carry prices down.
All components are designed by Bitter, from suspension design to the intricately machined metal backside bracket clusters holding the principle pivot and decrease shock mount. Bitter makes what they know greatest – welding butted 4130 metal. Then, they lean on their fellow German craft producers to do what they do greatest – working the aluminum rear finish, rockers, and geometry modify {hardware}.
Into the weeds of shared tech particulars & adjustable geometry
Each custom-butted & heat-treated 4130 chromoly metal frames function a custom-machined tapered headtube to suit an built-in headset (EC44/ZS56).
In addition they function related custom-machined metal backside bracket assemblies that matches a 73mm BSA threaded BB, the principle pivot, and the flip-chip.
Bitter designed the bikes with their geometry within the Excessive flip-chip place. They usually ship the bikes with alloy {hardware} for the Excessive/Low place – swapping to Low drops the BB 10mm, slackens the pinnacle angle 0.6° & slackens the seat angle 0.94°. However additionally they will supply a Mid chip to separate the distinction for any patrons wanting a middle-ground geo possibility.
Out again, the rear ends are all the identical, so that you get UDH compatibility, a replaceable direct Submit Mount 180mm brake bracket, a Syntace X-12 Enhance thru-axle, and max 2.5″ tire clearance. Bitter recommends 2.2-2.4″ tires for these sort of bikes, although.
Each frames additionally construct in a metal seatpost clamp (that Bitter says can all the time be chopped off & changed with a traditional clamp down the road should you ever injury it) for a 31.6mm seatpost. Cable routing is exterior on high of the downtube, however after all there’s inside dropper routing, too. The frames come commonplace with 1 set of downtube water bottle bosses, plus a set of braze-ons above the shock for a software provider. Non-compulsory extra cage mounts beneath the downtube and toptube bag braze-ons are additionally attainable.

As a substitute, Bitter created the Cowboy Cookie to have an efficient-pedaling ultra-distance bikepacking racer. Designed as a short-travel path bike or long-travel marathon bike, it combines a easy experience over any terrain with expedition-ready sturdiness.
Bitter athlete Quinda Verheul has put the brand new Cowboy Cookie by the ringer.
