No Hassle Returns
With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.
Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!
With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.
So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.
Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.
The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.
Call us if it's a bike as we can help arrange collection. Tel 01752 849315 or info@certini.co.uk

Head circumference
This measurement is the total circumference of your head. With tape level, measure the widest point of your head, approximately 1 inch above your eyebrows. Please note, that your helmet should fit snugly and not be able to move easily up and down or side to side when the chin strap is fastened. If this occurs, please try a smaller size.
