Reviews

Summary

The Vaast A1 gravel bike stands out for its unique magnesium-alloy frame, offering a lightweight, corrosion-resistant, and eco-friendly option with excellent ride quality and versatility. Its ultra-damped ride quality and good bottom bracket stiffness are frequently praised, though some reviews note quirky frame geometry and a few practical niggles like chain rub and awkward cable routing. The bike is often compared to models like the Pinarello Dogma and Kirk Precision for its innovative use of materials and performance.

Pros
  • Unique magnesium-alloyed frame material

  • Ultra-damped ride quality

  • Excellent versatility and ride quality

  • Good value for money

  • Responsive handling

Cons
  • Quirky frame geometry

  • Chain rub on chainstay yoke

  • Awkward cable routing

  • Creaky seatpost

  • Limited grip of the tyres on descents

Key Quotes
There’s a strange quietness and smoothness to how the Vaast A/1 rolls across coarse tarmac and rougher dirt roads, sort of like how a luxury car more thoroughly isolates you from the buzziness of ground texture.

The frame comes alive when the going gets rough with a sprightly spring to the tubing that’s as stiff as it is responsive, yet it controls vibrations and knocks with a wonderfully softening touch.

Vaast A/1 Allroad review

Oct 2022

As far as the best gravel bikes go, carbon fibre is the go-to material when it comes to frame and fork construction. And while it does have many benefits, metal frames can deliver an equally impressive riding experience, too, and I’m not talking about aluminium, steel or titanium here but rather magnesium. Yep, you read that right. The Vaast A/1 Allroad gravel bike represents a different take on the gravel bike recipe; a left-field, high-value option poised to do battle in what has become a rather claustrophobic space.

Vaast A/1 gravel bike review: Magnesium makes a comeback - CyclingTips

Nov 2020 · James Huang

Vaast is a new American brand built around Allite’s new “Super Magnesium” tubing. Claimed to be stiffer, lighter, more sustainable, and smoother-riding than aluminum — and at similar cost — Vaast is hoping to succeed where Pinarello, Kirk, and others have failed in the past. The A/1 is the brand’s versatile gravel model, and there’s […]

Highs
  • Ultra-damped ride quality, very good value, smart spec, gorgeous paint.

Lows
  • Quirky frame geometry, chain rub on chainstay yoke, goofy cable routing, awkward stock lever position.
