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:

Troika, Fat Bike Review

I am learning that the process of acquiring frame building tools is very long.  But finally, I can see the light at the end of the tunnel!  My last jig for mitering main tubes should be arriving after Labor Day weekend.  Also, the conversion from one phase to three phase power for my Bridgeport mill worked out fine.  I am using WEG CFW-10 VFD (variable frequency drive) with potentiometer allowing me easily adjust the speed of the Bridgeport motor.  Meanwhile, I’ve been riding Troika that I built at Metal Guru and can share my experience of riding on the “fat” wheels.

I’ve been test riding Troika mainly in the Tourne Park, little gem of the Garden State, which became my “backyard” mtb park.  This rugged park  is the only remaining undeveloped fragment of the Great Boonton Tract.  This area was purchased by David Ogden, colonial Attorney-General of New Jersey in 1759.  The main entrance of the park, McCarfey Lane, was created in 1767 to haul iron from Hibernia’s mines to Old Boonton where cannonballs were manufactured for Continental Army during American Revolution.

Tourne Park offers a bit of everything for mountain biking: ripping through single track, needling technical rock gardens and roots, leg burning rock and gravel climbs as well as hairy, technical descents.

Troika shows very stable ride downhill over loose rocky terrain because of the larger contact patch with the ground on 70 mm rims and 3.8″ tires that I run at about 7 psi.  The tire pressure and rim width dictate the amount of footprint on the ground.  Hence, the wheels with wider rims and lower tire pressure increase the contact patch, which in turn provide for a more stable ride downhill and cornering.

In addition, Troika does not slip during high-grade climbs over gravel.  I had a non-slipping ascend to the top of the Tourne during test riding.  Troika’s rear wheel equiped with Surly’s Nate 3.8″, 120 tpi (threads per inch) tire with super large knobs sticks to the ground extremely well.  Going over the logs and large rocks is not a problem either.  As I expected, Fat Bike performs as an all terrain bike.  I have no doubts that Troika will even be more superior ride over anything I owned in the past when riding during wet and snow conditions.

Below are few photos riding Troika in the Tourne.

Happy Trails!
