Extralite ExtraBolt 18 ultralight Center Lock disc brake rotor locking ring. Made of 7075T6 CNC aluminium, thanks to the super refined design weighs only 5.45 grams and it's one of the lightest on the market and allows a weight saving of over 30% compared to the original Shimano one. Compatible with all Center Lock hubs and disc brake rotors. Comes in black or silver anodized finishing with the laser engraved "Extralite" logo. Can be tightened with a Shimano TL-UN70 type wrench or with a compass tightening wrench with 3 mm diameter pins (maximum tightening torque 30 Nm, thread length 5.3 mm). The package include a single ring nut, so for a complete bicycle you will need to purchase two. 100% Made in Italy.

Extralite ExtraBolt 18 is a locking ring for disc brake rotors with Center Lock standard, it is made of 7075T6 aluminum finely machined from solid through CNC milling and has a stainless steel anti-abrasion washer.

The finish of the ExtraBolt 18 locking ring is anodized, available in your choice of black or silver. The laser-etched "Extralite" logo completes the elegant and durable finish.

The ExtraBolt 18 locking ring allows you to fix any disc brake rotor with Center Lock standard to any wheel hub with Center Lock standard. To tighten the locking ring you can use either a Shimano TL-UN70 type wrench or a compass tightening wrench equipped with pins with a diameter of 3 mm. The maximum tightening torque allowed is 30 Nm and we recommend using a medium threadlocker (Loctite 243) on the thread of the locking ring which has a length of 5.3 mm.

With a weight of just 5.45 grams, the Extralite Extrabolt 18 center lock brake disc rotor locking ring is among the lightest on the market and allows a weight saving of over 30% compared to the original Shimano locking ring. This was all achieved through super-optimized design and refined workmanship. The final result, while maintaining safety and practicality of use, not only allows you to save weight but also adds a touch of elegance and refinement to a detail that the most attentive and demanding enthusiasts cannot overlook!

The ExtraBolt 18 locking ring is sold individually but obviously on a bicycle you generally need two, one for the front disc brake rotor and one for the rear disc brake rotor, so in this case make sure you buy two.

The Extralite ExtraBolt 18 Center Lock Locking Ring is 100% Made in Italy.

AMP (All Mountain Project) pair of very high performance brake pads. The special carbon fiber back plate guarantees a 25% lower weight, better vibrations properties (ride in silence) and better thermal capacities (much less heat is transmitted to the pistons and consequently to the braking fluid). The ceramic compound is designed to offer maximum performance and make the most of the advantages provided by the composite material back plate. Recommended for intense and prolonged use, even in wet conditions and on E-Bikes. Compatible with various Sram-Magura-Trickstuff-Campagnolo braking systems (you will find a detailed compatibility list in the product sheet). The pair of brake pads weighs only 15 grams. |
