What about customs?

We are not responsible for any custom fees once the items have shipped. By purchasing our products, you consent that one or more packages may be shipped to you and may get custom fees when they arrive to your country.

Yes, you will receive an email once your order ships that contains your tracking information. If you haven’t received tracking info within 5 days, please contact us.

My tracking says “no information available at the moment”.

For some shipping companies, it takes 2-5 business days for the tracking information to update on the system. If your order was placed more than 5 business days ago and there is still no information on your tracking number, please contact us.

Will my items be sent in one package?

For logistical reasons, items in the same purchase will sometimes be sent in separate packages, even if you've specified combined shipping.

If you have any other questions, please contact us and we will do our best to help you out.

Mounted on 11 v single-plate as a guide roller, when i try to get down to the last pinion on the 9, it doesn't turn it down.

Delivery to msk-25 days with track. Bearings are really ceramics, but backlash-in the best traditions of shimano. Pollen on one side of the bearing is not, like, solid to score, that is :-) and most importantly, the trouble with the chamfer on the protective covers-everything will be in sand and dust. Write who was working on it.
