You must have the proof of purchase and you must be the original (first) owner of the product. The proof of purchase is a filled in warranty card together with the receipt or invoice.

All NS products have a one year warranty. Some may say that this is not a long time, but we think that it's better to give you a clear and solid one year deal than a vague lifetime warranty that has dozens of factors that will void the warranty. We have seen warranties on dirt jumping products that say that the warranty will be void if “the bicycle is used for acrobatic stunts”!

“EU Directive 1999/44, has the following qualifications: There is a window of two years from delivery of a consumer product during which the consumer may claim that the product was defective at the time of delivery. Although this period is often misinterpreted as a mandatory two-year warranty period, it is not the case. For example, if a product was purchased with an undetectable defect but that defect became apparent after a few months, then the consumer would have a claim against the seller under EU Directive 1999/44 to repair the defect. If, however, the product was purchased without defects but began to demonstrate reduced functionality after a reasonable period of wear and tear during the first two years, the consumer would not have a claim against the seller under EU 1999/44.”

So to summarise this: if there is anything wrong in your product at the time of purchase (an incomplete weld, an improper alignment, bad thread, a crooked frame etc.), then you have a 2 year period during which you can report this problem and expect to have your product replaced. But this has nothing to do with for example, a frame that cracks after jumping from 2 m to flat, 4 hours daily for two years. This frame will crack not because there was a defect at the time of sale, but because it is fatigued. However, your 1 year NS warranty will cover this kind of failure for one year from the date of purchase.

The following parts do not classify for warranty replacement: bearings, chains, chainrings, brakepads, tires, tubes, decals, saddle covers, grips. Damage to these parts is almost always a result of normal wear and tear, and they should be replaced by the user when they become worn out. The following types of damage does not qualify for warranty replacement: discolorations, damaged surface finish, dents, bent parts, damaged resulting from incorrect assembly or improper use. The general rule is that we will replace parts that are damaged due to normal riding (even if it's heavy duty riding). However parts that are damaged due to crashing, throwing the bike or casing jumps will not be replaced. Damage resulting from this kind of total overload can be replaced under the Crash Replacement policy. In other words, we will warranty most cracks in products for a one year period, but we will not warranty bends, dents or parts that are ripped apart.

Our official position is NO!! We strongly discourage you from making any changes in the products for safety reasons. Remember that tampering with the products means that you are taking a big risk that the product will fail and you will hurt yourself seriously. However we won't make artificial problems with the warranty - for example, if you cut your dropouts and the frame cracks at the headtube, we will warranty the frame. But if you cut off the cable guides, damage the tube and it cracks - then we won't warranty that case.

Damage resulting from crashing, casing jumps or throwing the bike won't be covered by the normal warranty, but we do offer the possibility to replace the product for 50% of the original suggested retail price. There are a few conditions:
- we reserve the right to deny Crash Replacement without explaining our reasons.
- Crash Replacement does not apply to parts damaged in other situations than riding - for example if a car runs over your bike, CR won't apply!
- Crash Replacement does not apply to complete bikes. It only applies to components made by NS that are mounted in the bikes.

1. Find the documents for your product. Read the warranty conditions, and decide if the problem could potentially be classified as warranty.
2. Make a photo of the problem and send an email to the company that sold the product to you, asking them what you should do.
3. Most probably, they will ask you to send the damaged product for inspection to them, or to your national distributor. Remember to make sure that you put the proof of purchase, warranty card and your contact details in the box!
