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.
