Bike Of The Week: Brett's Rosko 29er Single Speed MTB

The latest Bike Of The Week is homegrown.  NYC Velo’s own Service Manager, Brett Champlain, offers his custom steel Rosko single speed MTB 29er for review. Brett who focuses on endurace MTB events and cyclocross racing, recently completed Iron Cross 11 on the bike in question before sending it off for a coat of paint. He needed to race the bike in Pennsylvania in his search for inspiration for the final color of his new race machine.  A goal of Brett’s is to complete the Great Divide off-road race on this very bike.  See pictures below of the bike in its raw, unpainted form:

Brett, as the Service Department’s go to guy for custom wheel assemblies, he laced up hubs from Paul Components in California to Velocity (manufactured in Florida) Blunt tubeless-specific rims. The fork is a uni crown design with tapered fork blades made by Rosko in Brooklyn.

After compressing the top cap and fastening the stem, Brett removes the top cap to create a “storage container” for use during competition.

Seth Rosko also built Brett’s Cyclocross bike, finished in the same green hue as the temporary decals on this frame.

In it’s current form, the frame retains an authentic race patina.

Not surprisingly the bike is fitted with a Chris King headset and a Ritchey stem and bar combo.

With endurance racing in mind, Brett instructed the builder to make provisions for a 3rd water bottle mount on the down tube.

The drivetrain utilizes British-made Middleburn cranks with a 32 chainring and Shimano XT clipless pedals.

Brett is running a 19 tooth freewheel from White Industries of California.  The rear dropouts are Swinger models, courtesy of Black Cat.

Shimano’s hydraulic XTR brakes ensure that Brett manages his speed appropriately.

This bike is super light, fast and smooth to ride, we all wish Brett much success as he takes it to the trails!

3 Months Later: NYC Velo's Memorial Day Ride

On Memorial Day 2013, 3 of NYC Velo’s mechanics scouted routes in the Catskills for future shop rides, with many of the roads (and trails) making their way into Brett’s Revenge on the Catskills 2 months later.  The day’s ride would involve a coffee refuel in Windham, off road sections near Palenville, and some BMX sessions off of Hwy 23.  Wilis brought along his analog 35mm camera to document what would end up being a solid day in the mountains.

Stay tuned for more Shop Rides this fall!

Bike Of The Week: ROSKO 650B MTB

Seth Rosko is a Brooklyn-based custom frame builder, a good friend of the shop, and an all around rad guy.  Among other things, he’s built cyclocross racing frames for a few of the mechanics and shop employees here at NYC Velo. With more projects in the works, Seth let us borrow his personal 650B SS MTB to test out the intermediate wheel size and new frame angles.  After a few weeks of riding, we’re stoked on the design and the execution – Great Job once again, Seth!

Bike of the Week: (Brett's) Rosko Custom Cyclocross

Seth Rosko builds steel frames quietly in Brooklyn with little fan-fare or publicity.  As a bike builder, he draws on his experience racing and fabricating vintage motorcycles, and his many years of work under the Brooklyn Machine Works (known for their Gangsta Track, DH and park bikes) banner. Since setting off on his own, Seth seems eager to challenge himself with designing frames to fit the individual rider, from road to BMX bikes.  His background serves him well as he succeeds in achieving understated form driven by function, frames speak in pure, purposeful designs for aggressive riding and racing.  There are no hand-carved lugs, no polished head-badges, just precisely machined bits from Paragon Machine Works, thoughtfully affixed to quality tubes, in this case Columbus tubes adorned with glittery Granny-Smith green.

Made-in-the-USA Chris King, Thomson, Zanconato, and Parlee components make a bike that its owner calls “Practical Fancy.”  The rims are alloy, the brakes are cantilever in spite of the looming disc-for-cyclocross hype, the Challenge tires are glued on, and the ceramic bottom bracket is of the Pressfit 30 variety, to combine the old and new school.  The fork’s provenance is, according to the builder, top secret.

 

 

The beauty of purchasing a frame from a quality local custom builder is the inherently collaborative design process.  In this case, Seth’s long MTB/BMX building experience and Brett’s (the customer) urgent need to dote on details like bottom bracket drop, trail measurement and chainstay taper.  With Seth’s execution and precise welding, Brett received, according to him, “the most balanced riding, confidence inspiring bike I’ve ever owned”. And green means “GO.”
