For the environment friendly mass-production of mountain bikes, welded aluminum frames make a variety of sense. The Psalm 150 full-suspension body is designed with a distinct philosophy in thoughts, nevertheless, because it’s made from bonded sections of CNC-machined stable aluminum.
At present accessible for preorder, the US$5,000(!) Psalm 150 was designed by Washington-state-based builder Chris Currie. Amongst different issues, he beforehand based custom-built bike firm Speedgoat.com, and was answerable for branding for Stan’s No Tubes. He now runs his personal startup, Ministry Cycles.
Placing it merely, the entrance triangle of the Psalm 150 is made from two hole CNC-machined items of 7075 aluminum that get pressed collectively to interlock with each other, forming a skinny seam that runs laterally down the middle of the body.
They’re bonded collectively using an aerospace-grade adhesive, with lap joints and areas of 360-degree bonding used to maintain them secured and completely aligned. The rear swingarm is likewise made from two machined items of the identical sort of aluminum, joined to 1 one other through a bolted and bonded bridge.
As you may see, the completed product is way nicer-looking than conventional aluminum frames, with their huge ugly welds. That stated, aesthetics aren’t the primary cause for Currie’s distinctive manufacturing method.
“The essential body fabrication methodology is optimized for small-batch, limited-edition manufacturing, and the liberty to discover a variety of recent concepts in area of interest markets,” he informed us. “The manufacturing methodology can be designed to decentralize manufacturing, and anticipate a future the place the availability chain seems very totally different.”
He added that the Psalm 150 was designed primarily for sturdiness and suspension efficiency in all-around path situations, and that its weight is much like that of an analogous welded-aluminum body. Extra particularly, it weighs 8.4 lb (3.8 kg) and may reportedly be constructed up into an entire bike that suggestions the scales at round 34.5 lb (15.6 kg).
The Psalm 150 body is being provided with the customer’s alternative of a Fox Float X2, DHX2, RockShox Tremendous Deluxe Final RC2T or Tremendous Deluxe Coil Final rear shock, offering 150 mm of journey – therefore the “150” within the identify. It is designed to be used with 29-inch wheels and a 160-mm fork.
Currie is initially doing a restricted run of 20 frames, that are solely accessible in a Medium/Massive dimension. They need to attain consumers no later than Might 1st. Plans name for different sizes to be provided in subsequent manufacturing runs.
And whereas we all know the place the quantity comes from within the body’s identify, what in regards to the phrase “Psalm”?
“My purpose is to make bicycles that mix expertise and craftsmanship, precision and soul,” Currie states on his firm’s web site. “Most of all, it is about creating one thing particular that folks wish to personal ceaselessly. Bicycles are my faith, and that is my mission.”
We should always add that though the Psalm 150 undoubtedly is unconventional, it isn’t the primary “stable” aluminum body we have seen.
The Frace F160 is made from eight milled aluminum sections which are mounted collectively through titanium screws, and the body of Alutech’s CNC eFanes electrical mountain bike is made from two aluminum halves that get welded collectively. Moreover, in a course of extra like that utilized by Ministry Cycles, Pole Bicycles manufactures frames made from milled-aluminum halves which are bonded to 1 one other.
