I've notice that the business to business site AliBaba and it's more consumer friendly AliExpress website have a number of bike components for sale. They tend to be complete component groupsets and the like but are some quite reasonable deals, especially if you are building a bike from scratch.

I've used AliExpress before to purchase electronic components, which have been good quality and are what they say on the tin.

Has anyone used AliExpress to buy bike components and have they had any trouble? (quality, counterfeit etc.)

One benefit is that your money is held in escrow until you receive the item and aprove the payment so some safety.

One thing to think about is the product warranty. If I buy something at my local bike store, I know they will help me out if I end up having to return it for warranty. I don't imagine the same could be said for stuff purchased from AliExpress. I wouldn't be surprised if some if it was counterfeit. I've bought a few lights and non-functional items (valve covers, etc) from, and I was happy with those items. But I've never had the faith in ordering something from China that was crucial to the safety and proper operation of my bike. – Kibbee Dec 18 '12 at 20:22
I just looked at this site - did a search on "Assos" and instead of gear costing $200+ they're showing a jersey for $20. On a totally unrelated note, I remember hearing a saying once that if something looked too good to be true, it probably was! – PeteH Dec 20 '12 at 16:55
This question appears to be off-topic because it is about reviewing a specific vendor. – lantius Nov 27 '13 at 18:40

You may get something fantastic for your money, or you may get something that will leave you feeling burnt. Worse yet, you may get something that will fail catastrophically and get you really, really hurt. I have personally seen all scenarios play out with friends and former customers.

I recommend you try to find reviews for whatever parts you're looking at from folks who have owned the product for years- not months or weeks, or the "I just ordered it and when it gets here it's gonna be awesome!" guys.

I too am interested in this matter, and I plan on ordering some parts and maybe a carbon frame set.

I stumbled upon this forum of happy AliExpress carbon frame customers, there you can see real life builds based on carbon road and mountain bike frames and see what are the pros and cons:
