electrical bike Aurum Bikes Information – Greatest Highway Bikes

Right now, two road-racing legends revealed the following chapter of their careers. Aurum is the brand new bike model of Alberto Contador and Ivan Basso (the 2 are additionally companions in Bend36 skincare). With 9 grand tour wins between them, it’s not stunning that Aurum’s first bike is a UCI-legal road-racing bike, however a gravel bike is on the drafting board.

(If Aurum rings a bell in your cranium, it’s as a result of Norco calls its downhill bike the Aurum.)

The disc-brake-only Magma cuts a clear and considerably conventional profile. It has a level-ish prime tube and customary seatstay attachment. The corporate claims the design’s general objective is steadiness, with stiffness, weight, consolation, and aerodynamics all considered.

The ensuing body boasts an 805-gram claimed weight (54cm, unpainted), with truncated airfoil shaping (primarily based on NACA shapes) designed in CFD and validated within the wind tunnel. Aurum didn’t present aero information, nevertheless. Consolation, Aurum states, is helped by the skinny seatstays and fork legs.

The underside bracket shell follows the BB386 EVO customary—at present the widest and largest diameter customary—which helps Aurum obtain its stiffness targets by offering actual property to connect a big down tube, in addition to “tall and extensively spaced chainstays.”

The Magma is available in six body sizes (50, 52, 54, 56, 58, and 61cm). Every body measurement has distinctive tubing shapes and dimensions in an try to keep up the identical really feel and dealing with throughout the vary. This tuning extends past the entrance triangle: Each body measurement has a novel one-piece rear triangle. The utmost acknowledged tire clearance is 30mm.

Although it’s a fashionable race bike, the Magma is freed from proprietary components. It makes use of a spherical 27.2mm submit (with hidden binder), the fork steerer is spherical with a standard 28.6mm diameter the place the stem clamps, and comparatively simple brake-hose and derailleur-housing routing.

Brake hoses route into the entrance of the pinnacle tube. The entrance hose then routes into the fork steerer earlier than rising from the leg above the caliper. The rear hose travels alongside the down tube, across the backside bracket, and into the chainstay. Digital drivetrain wiring additionally routes right into a head tube port, however mechanical drivetrain housing routes by a port on the down tube’s topside.

With digital drivetrains, this routing system supplies almost-hidden brake hoses, which reduces aerodynamic drag, with out the effort of inner bar or stem routing. Meaning switching bars or stems doesn’t require disconnecting and rebleeding the hydraulics. Mechanical drivetrains will produce extra drag due to the uncovered derailleur housing, although servicing the cables and housing is less complicated than a full-internal system when upkeep comes due.

The Magma’s geometry doesn’t stray a lot from established road-racing numbers. A measurement 54cm Magma’s numbers are inside millimeters of a 54cm Specialized Tarmac SL7. It’s comparatively lengthy and low, with aggressive angles (parallel 73 head and seat tube angles on measurement 54 and up). The 2 smallest sizes, 50 and 52, use a 50mm-offset fork to cut back toe overlap and have 60mm of path; the remainder of the dimensions run makes use of a 44mm offset fork and has 59mm of path.

The Magma does have a less-sloping prime tube than many race bikes. In comparison with a 54 Tarmac SL7, the Magma’s seat tube is about two-centimeters longer (504mm vs. 475mm), which interprets into taller standover (782mm VS. 768mm). The Magma has two headset cowl choices: 8mm for a decrease place and 20mm for a extra upright stance.

The Magma rolls out in two colour choices—Glacial Blue and Carbon Black—and three construct kits. The Shimano – Enve construct has Shimano’s Dura-Ace Di2 drivetrain and hydraulic disc brakes with Enve SES 3.4 disc wheels, and Enve carbon bar, stem, and seatpost. There’s additionally the Shimano – Light-weight construct, which has the identical Shimano components however makes use of Light-weight Meilenstein Evo Disc TL wheels, with carbon bar, stem, and seatpost from Light-weight. The ultimate construct is SRAM – Zipp with Crimson eTap AXS brakes and drivetrain with Quarq energy meter, Zipp 303 NSW wheels, and Zipp carbon bar, stem, and seatpost. All builds use Schwalbe Professional One 25 tires and Prologo Scratch M5 Nack saddles.

Aurum bikes aren’t but out there within the USA. A spokesperson mentioned, “Availability within the U.S. is a bit later subsequent yr. Costs in U.S. {dollars} weren’t out there, however within the EU, framesets promote for €4,099 (USD 4,778 at publication time) with full bikes beginning at €9,799 (USD 11,421 at publication time).

Now we have a overview bike on order. Search for our overview of the Aurum Magma quickly.
