Southern California’s Poseidon Bikes had their new mountain bike, The Norton, on display at this year’s Sea Otter Classic. Poseidon Bikes is a company that has come to be known for its truly affordable sub-$1000 bicycles, like the Triton road bike for $699 (with a carbon/aluminum fork), the X Ambition at $899 (with a full carbon fork), and their gravel plus bike, the Redwood at $999.

The Norton was launched about a month ago and this is the first time I’ve seen it up close and personal. This is Poseidon’s first bike that breaks through the $1000 threshold, retailing for a bit more at $1299. It is a 27.5″ wheeled hardtail that has modern geometry.

The aluminum frame features a tapered head tube and routing for a dropper post (dropper not included though). It’s got internal cable routing as well with an option to externally run your rear brake cable or hose if desired. The Norton also has thru-axles front and rear, with standard 12 x 148mm Boost spacing out back.

I thought one of the highlights of the new Norton’s spec sheet were the brake calipers. Poseidon used the very capable Juin Tech Hydraulic/Mechanical Disc Brakes.

The Norton comes in either Electric Green or Matte Black colors and is available as a frame only as well ($449.99 frame-only). The Norton’s frame uses smoothed-out welds for a neat and clean aesthetic.

Let’s see what else the Norton MTB has on the spec sheet.

I can overcome anything, but not those brakes. How much would have they paid for a cheap set of Gemini or Clarks?

You can buy Shimano hydros for like $35. Will take having to swap out the crappy brakes vs QR wheels that usually accompany bikes in this price range.

You’d have to switch out the shifters as well. At that point you should just get a better spec’d bike at the same price range.

Sweet! I’d just throw a 1x slx 12 speed with cheap cassette, and some cheapie Shimano Hydro brakes on this bad boy and you’d be good to go.
