Feature Details Of Diamondback Mason

Outstanding Frame

DB Bicycles Mason Comp Frame

Cruising mountain and steep slopes never come easy. Imagine going on such a trail with a weak-formed bicycle frame? Expect bends and irregular flow at the end. That said, like other hardtail bicycles, the Diamondback Mason comes with an incredible, innovative and forward-thinking frame geometry. Unlike other predecessors, its frame has been kept quick and stable.

This is perhaps due to the Diamondback Mason 27.5” plus 6061-T6 weapons-grade aluminum frame with double-butted formed top-tube, down tube, seat stays and a tapered headtube. Alongside the frame is an attacked 148x12mm boost spec dropouts with a replaceable hanger.

High-Quality Tires

Mason Comp Plus Tires

Roughing up the mountainous terrains and steep slopes aren’t such an easy task. Isn’t it? Experienced riders will attest that it takes strong tires to complete such a track without a prick. Otherwise, simple tires will give in to brake pressure and bumps among other obstacles. It could also easily skid off resulting in an accident.

That said, with its 27.5 plus tires, you can comfortably tackle downhills or soak up the undulating and twisting mountain trail without flicking. As a riding enthusiast, you should probably know that having your tires with low pressure sticks the bike to the ground. However, these incredible tires work both at low and high pressure.

Utmost Riding Comfortably

Riding a bike over steep terrains calls for undoubted comfort. Otherwise, completing the trails will be impossible. Actually, you cannot ride better with an unstable, narrow or saddle not properly positioned. You may also want to adjust your saddle height based on various riding situations. Riding comfort is also contributed by the size of the bike.

Therefore, to achieve a good riding comfortably, the Diamondback Mason Comp bike comes with a DB Race M-series saddle. It is complemented by the KS eTEN Integra Dropper saddle for height adjustment. There are also four size classifications. Choose a perfectly fitting size.

Wide Handlebar

DB Mason Comp Plus Handlebar

All-mountain bikes need to meet some standard handlebar requirements. This is to ascertain comfort as well as provide a nice grip. Due to the nature of the escapade also, the handlebar needs not to be extra wide/long. This will ensure that you maneuver the trail without crashing on plants or other narrow terrains.

That said, the Diamondback bike comes with a DB35 Alloy, 760mm wide, 15mm rise and 35mm bar bore handlebars. Grips fitted on the handlebar are the excellent DB4L lock-on 135mm Kraton type. With such handlebar dimensions and grip, be certain of a fulfilling riding experience.

Mountain Conquering Drivetrain

Mason Comp Plus Drivetrain

One of the major setbacks of mountain bikes is the drivetrains. Whereas some bicycles have excellent frame geometry, tires, handlebars, brakes and rims, the drivetrain lets them down. A powerful bicycle’s drivetrain results in an easy ride. Note that the drivetrain comprises of various components.

Worth noting are the rear derailleur, shifter, Cogset, and chain. All should be complementary. They should also support the bike’s speed which is dictated by the gear system. That said, this bike has an SRAM GX X-Horizon rear derailleur, SRAM GX X-actuation shifter, KMC X11EL chain and SRAM XG1150, 10-42 Cogset all supporting 11-speed.

Sharp Braking System

Diamondback Mason Brakes

Accidents and the resulting bicycle damage can be reduced by having an excellent brake system on a bicycle. Since the inception of the disc braking technology, all bikes have moved to this new system. It is perhaps the best braking unit due to minimal mishaps. This is what the Diamondback Mason took advantage of.

The bike is outfitted with an SRAM Level T hydraulic disc brake with 180mm front and rear centerline rotors. This facilitates easy stopping regardless of the speed you were cruising in. Controlling your speed on any sloppy trail won’t bring some headaches.
