Check the countries we currently ship to. Shipping is usually around $13 - $16 USD for one stem/one package. If your country is not listed, please email us and we will find out the shipping expense to your country. Please be aware that we ship all our items from our logistics center in Taiwan. Import duties, taxes, and other country specific charges are not included in the item price or shipping cost. We don't know what these may be for your specific region. These charges are the buyer's responsibility and if there are any such charges, the buyer will have to pay upon receipt of goods. Please check with your country's customs office and FedEx to determine what these additional costs may be prior to ordering.

We accept PayPal who also accepts Visa and Master Card through their system.

Usually around 5-7 days.

After receiving your order, we ship out the stem and then Paypal will send you a tracking number.

We ship out the stem as soon as we have received verification that a product has been paid for. If we don't send you a tracking number, this most likely means that there is a problem with PayPal, Mastercard or Visa. Please email us directly and we'll look into the situation right away.

If you are a distributor or dealer, we would welcome the opportunity to work with you. Please contact us and we can discuss our distributor and dealer pricing/shipping/methods of payment.

ATS stands for Adjustable Threadless System. The ATS Shim was designed to fit with NVO stems over threadless headsets.

Absolutely not. This is an incorrect use of the ATS Shim. The Shim needs to extend about 2-3 mm above the steer tube. If your steer tube is cut, then you must cut the ATS shim as well. You may not have maximum height adjustability, but you have the other benefits of travel convenience (headset stays preloaded when you take the stem off), steer tube protection and fewer steering parts.

We feel 6061 T-6 aluminum gives us the best balance between weight, durability, and cost. Although 7000 series aluminum has higher tensile and ultimate strength, there is a cost associated with it. It’s more expensive and more brittle than 6061. A correctly engineered stem made from 60061 T-6 will provide many years of reliable service.

This depends on the length of your steer tube. If you have a long or uncut steer tube, then most likely you can use the entire length of our longest ATS shim (100 mm). Our standard length that is packaged with each stem is 80mm, giving you 40mm of possible height adjustment. We also sell our ATS Shim and Top Cap Package separately and these are available in the following lengths: 80 mm ATS Shim:  40 mm of adjustment 85 mm ATS Shim: 45 mm of adjustment 100 mm ATS Shim: 65 mm or adjustment

Currently, our system is designed to fit 1-1/8th steer tubes.

You must follow the torque settings that are indicated on the rear clamp bolt. We have engineered, optimized and tested all NVO Components stems thoroughly. All of our stems pass EFBE testing, which is the most rigorous testing standard for bicycle components.

If for some reason you don't like your NVO stem, simply remove the top cap, the stem and the ATS Shim. It slides right off of 28.6 mm steer tubes. Now, replace it with some spacers and your stem of choice.

Bicycle stems are measured from the middle of the bar bore clamp to the middle of the top cap, parallel to the ground. With a negative degree stem, there will be approximately 5 mm decrease in length vs a positive degree stem. For example, our F2 flip flop stem, in the -7 degree position will be 90mm and in the positive, +7 degree position, it will be 95mm. Our TM-2 stems are regarded as negative degree stems, and come in sizes: 90mm, 110mm,and 125mm.

We have 25.4 bar bore sizing shims available just for this purpose. Please see the Shop page.
