Surface - Purple - L

$3,876 $4,218

The Surface has probably the least extreme geometry of the bunch, but don't let that fool you, it was still designed right here in Whistler so it can still take a few punches, and even hand out a few.

The Surface features longer front end, slacker head angle, steeper seattube, shorter chainstays, and bb height adjusted for longer travel (150mm). We are now using 148 boost rear axle spacing and a new ‘yokel’ layout for increased tire clearance. The Surface is a 29er but will also accept 27.5+ tires up to 2.8” or possibly more.

Almost all Chromag frames are made from quality 4130 chromoly steel tubing. Chromoly is an abbreviation for chromium-molybdenum indicating the materials that the steel is alloyed with.

The added chromium helps increase the steels hardenability and also provide some corrosion resistance.
The molybdenum helps to increase the toughness of the steel.

It has a high tensile strength but is also malleable which is what gives our frames their notorious ride quality and feel. Chromoly is often used when more strength is required than that of mild carbon steel.

It falls under the AISI (American Iron & Steel Institute) 41XX designations which is where the “41” comes from. The “30” indicates it contains approximately 0.30% carbon by weight.

Chromoly is much stronger than traditional 1020 steel and it has a higher strength to weight ratio and high tensile strength, which means we can use less material and achieve a product that can withstand the abuse that riders love to throw at it.
