The shipping in China stopped for 1 week for the new year

NXS is a network for bicycle components. Think of it like WIFI. You have a hub, and can connect other devices or computers to it. NXS uses one of your components as the hub, and you then connect the other components. NXS is designed with an open API. In the future, other component manufacturers will be able to launch their own NXS compatible wireless components.

In a word, Quantum is awesome! Quantum is a very small and light wirelessly controlled servo motor. You connect it to your front or rear derailleur. Its been designed for modular mounting, and parametric software, so in theory it can be used for just about anything that needs a cable pulled.

We would love to provide all free shipping. But due to the global conditions, shipping fees are currently very high. Orders $150 and over will be free shipping. Less than $150, it will be a $25 shipping fee.

We will first release an Android only APP. Later this year the iPhone version will be released.

Yes you can, however you will not have full range. The Quantum has 42mm of stroke, and the Alipine 11 requires about 55mm. Later in 2022 we will produce an extended range model made for IGH (Internal Gear Hub).

Yes it does. It includes the Quantum servo, rear derailleur adapter of your choice, Shifty buttons, charger, battery and the BlakBullet hub. Kit includes cables and mounting hardware. You can add extra battery and cable to the order if you desire.

Yes you can! We offer a convenient 13mm frame mount adapter. Mount Quantum anywhere you want and connect with a derailleur cable.
NOTE: You need to use shifting cable, do not use a brake cable!

Absolutely. No questions asked. If you cancel before we ship, we are happy to refund in full, within 24 hours. Just go to your order screen, and file a help ticket for pre-order refund.

We ship to most countries. There are some exceptions, such as Russia, Belarus, Brazil and some other countries that are very difficult or expensive to ship to. Contact us if there is no shipping option available.

The components for the NXS system are sourced globally. Final assembly is done in the Philippines.

Initially it will not be. If there is enough demand, we will make a firmware update for the XShifter pods. Unfortunately, the ELink will probably not be backward compatible. If you are a current XShifter owner, contact us for special discounts to upgrade.

Minimum system requirements: 1 Quantum, battery, charger, BlakBullet hub, and BIT or Shifty buttons. The kits have everything needed.

Well, its not as tough as a forged aluminum or steel front derailleur. but we believe its durable enough for road bike use. The carbon fiber blades are replaceable, should they wear out. We do not recommend this derailleur for downhill or serious off road riding.

Yes, there are several options. You can use “ability” buttons. These are usually large gel type buttons you actuate with elbow or chin. Or, you can mount the blakbullet hub and a set of shifter buttons to the hand crank. You can put 2 buttons on one side, or you can use a BlakBullet and button on each side for double control.

Yes we do. We currently offer the “Claw” CNC machined frame mount. It is available in multiple sizes.

We do not have fully automatic shifting. But we do have semi-auto shifting. You just use 2 buttons, up/down to shift through both the front and rear derailleur. You need to preset the teeth count for all cogs, and then NXS will figure out the best gear combination.

Yes it is, and more. We allow the user to manually lockout any particular gear combination. If you try to shift into that gear combo, it will just skip past to the next one. This is very useful for anti-cross chain, as well as skipping over troublesome gears.

You need to carefully measure the threads on your barrel adjuster. The Quantum adapter will thread into the same hole. Typically Shimano uses M5 and SRAM uses M6, but there are exceptions. We will try to build a database of correct sizes as time goes.

See the adapter chart here.

Normally we except credit card and Paypal. But unfortunately, we cannot use Paypal for pre-sales, since it violates their terms of service.

If you are connecting to a Brompton, probably you will use a shifting inner and outer cable. You can’t connect Quantum direct to the Brompton special shifter. So, choose the Tube adapter. It won’t matter which thread size or tube angle because you probably won’t use those components.
