Rigid 29er/CX Flat Bars Bike

Quote

Cyclocross bike with flat handle bars?  Well, rider wanted a custom frame and fork with Cyclocross geometry, however, no drop bars.  The bike is going to be used half of the time on-road and half of the time off-road, primarily hardpacked dirt.  No long distance rides or bombing down steep mountain hillsides.  In addition, frame required to have lots of stand over, disc brakes and stand out from the crowd.

To achieve above objectives, we fabricated bent top tube and bent wishbone seat stays for extra stand over and desired aesthetics out of 0.035″ aircrcaft 4130 chromium-molybdenum steel alloy tubing.  Down tube, chain stays, head tube and braze-ons were supplied by True Temper, Columbus and Paragon Machine Works.  We prepared the tubes to run internal cable routing for cleaner lines.  As usual, Vicious Cycles did a great paint job on the frame and fork.

Frame was built with CX geometry.  We fabricated steel fork with 395 mm axle to crown measurement and 47mm rake with clearance to run WTB 40c Nano tires.  Currently, bike is equipped with Rolf Ralos XR 29er wheel set and Clement LAS 33mm tires.  Clement LAS tires allows speed on road and hardpacked dirt due to its file tread, and cornering on off-road due its small side lugs.

The bike’s drivetrain is a combination of Shimano CX50 (cyclocross) and Shimano Deore XT 10-speed (mtb) drivetrains.  Shimano CX50 includes crankset, front derailluer and two 46/36t chain rings.  Deore XT parts consist of 10 speed cassette, rear derailluer, shifters and disc hydraulic brakes.

Mission accomplished, and that’s why we do what we do…because we love it!  Thanks for checking in and enjoy the pictures.  Visit Chicagoathlete and Oldglorymtb for more coverage on this bike.

Stay tuned for more on our next Road/Gravel project.

Dexter’s Single Speed 29er-Black in Black

Another single speed frame was finalized.  Dexter chose to build his frame with Reynolds 853 air-hardening steel tubing and Paragon rockers adjustable dropouts.  The geometry of the bike is suspension corrected.   It will have Fox, 100mm travel, tapered steerer fork.

The frame was powder coated in black matte color by Coast2Coast.  Dexter wanted to have black color frame with black decals.  I was a little skeptical of his choice, but in the end it came out really cool, stealthy looking frame.

Here are few pictures of the frame and a happy customer.  Thanks for checking in!

P.S.

New project, road frame, is in the works for Gran Fondo New Jersey 107 miles race.  Stay tuned!

Vlad’s Single Speed 29er, part 1

As the Spring is here after the long and brutal Winter, I’ve started to work on my own single speed 29er.  I am using Reynolds 853 butted/heat-treated and air-hardening steel tubing and my favorite Paragon rockers adjustable dropouts.  What is interesting about Reynolds 853 steel alloy is that strength of the steel is actually increases after cooling in air post welding.  I am using Reynolds’ bent downtube for better fork clearance.  The bent down tube allows me to use a shorter head tube as well.

To complicate things a bit, this build will be with shorter chainstays than my earlier frames.  The effective chainstays length will range between 410 – 422mm (16.1 – 16.6″), which is possible due to adjustable dropouts.  So, for my longer rides I will set the chainstays at the maximum length by moving the inserts of the dropouts, and for the rides with lots of switchbacks and climbing I will set the stays at the minimum length; or I will find a perfect spot between the range mentioned above.  The shortest chainstays that I rode on 29er were 17″, so I am interested to see how this bike will handle on the trail.  In addition, I am experimenting with Anvil’s bender by adding nice curves to the seatstays. 

The geometry of the bike is suspension corrected around Fox, 100mm fork.  It will have 44mm Paragon head tube and adjustable dropouts that allow chain tensioning to run a single speed drive train.

Thanks for checking in and enjoy the ride!

 

Dino’s Single Speed 29-er, part 2

Although this Winter was unusually cold and long in New Jersey as it would never end, it seems to finally start caving in during the first week of March.  I have not been riding during this Winter much, but I am hoping the weather is going to cooperate and let me go back on the trail.  One good thing came out of this winter is that Dino’s SS steel 29er frame is all finished, just in time, as the Spring is slowly coming our way.

The frame is welded using Dedacciai Zerouno tubing, Paragon 44mm head tube and Paragon Rocker adjustable dropouts.  The frame is suspension corrected for the Fox 32 29er, 100mm travel, taper steerer (1 1/8″ – 1 1/5″) fork.  Rigid fork could be used as well with 480mm axle to crown measurement.

New frame and fork fixtures arrived from Anvil and I am super excited about that.  The upcoming project will be done with Anvil’s tools of course.

Check out the photos of Dino’s frame and stay tuned as new 29er is in the works.

Happy Trails,

Dino’s 29er, part 1

It’s been six month since my graduation from Metal Guru bicycle fabrication school and I am working on the 4th frame since the school.  Doesn’t seem too much, but considering that I have a full time job, things are moving along according to the plan.  During these six months I acquired Bridgeport mill, Sputnik’s main tube/stays mitering jigs and Anvil’s tube bender.  In addition, I just ordered from Don Ferris his Journey 3.1 Frame fixture as well as other cool staff to make things done quicker and with better precision.  I am currently selling my Bringheli frame fixture, so if anyone is interested here are the links to listings on Ebay and Craigslist:

The frame I am working on right now is for my friend.  He wanted a single speed 29er to run it with fox suspension fork.  I am building this frame with Dedacciai Zerouno tubing, Paragon rocker adjustable dropouts and 44mm Paragon head tube.  The frame has been tacked already and below are few photos of the build process.

In addition, Jen Green from Revolution Cycle Jewelry just redesigned my Troika head badge.  It is totally cool!  The inspiration came from Dubossarsky and Vinogradov artistic duo.  Here is the preview of the badge:
