Pre-Order

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!

Pre-Launch

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

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.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

Hassle free returns

Your rights to return goods are protected under the EU Distance Selling Directive.

You are entitled to cancel your order and return the goods within 30 working days for a refund less the cost to us of shipping the goods to you initially. Your refund will be paid within 15 days. You are responsible for the cost and risk of loss or damage when returning the goods, so you should take out enough postal insurance to cover their value. This cancellation policy does not affect your rights when we are at fault - for example, if goods are faulty or if we have sent you an incorrect item.

Any goods returned must be in the same perfect condition as when purchased (including their packaging). Some items cannot be accepted for return due to safety or hygiene reasons - Cycle Helmets, sunglasses, underwear, and socks are included in this category. The goods must in an ‘as new’ condition and returned in the original, undamaged packaging, along with any accessories and free gifts received with them. You can examine the goods as you would in a shop but you must not have used or installed them or input any data on them (electrical items).

If we send out an order and it is returned due to non-delivery for any reason, we will refund the item but not the shipping amount paid for the order. This includes 3rd party or P.O. Box delivery addresses. Should the order be refused by the company it is considered the equivalent of the customer rejecting it themselves.

All returns should be sent to this address (and can be returned by hand if you are local) with a note requesting whether you wish for a refund or exchange:

The Edge Sports Internet Returns
37-38 Kinsale Road Commercial Centre, Kinsale Road, Cork T12 P8KF

If you are returning from outside of the EU, and if we have to pay any charges to receive the item that is returned, you agree that this will be deductable from your refund. We recommend that you state the item is a "Product Return" so that no customs charges should be levied before arrival at the shop. You are fully responsible for any return you send to us until we receive it. Please use a tracked delivery method for your own peace of mind.

If you are returning to us in Republic of Ireland, we have partnered up with An Post to make returns easier. You can create a return on this page and use it to create a label / drop off to an An Post collection area (subsidised cost of €7) or have a parcel collected from your home (€8.50):
https://www.anpost.com/Post-Parcels/Click-and-Post/Returns.

These terms apply to your order. We may change our terms and conditions at any time, so please do not assume that the same terms will apply in the future.

None of these terms affects your legal rights and these are not diminished in any way. Suppose any term is held to be invalid under any applicable statute or rule of law. In that case, that term is automatically omitted from the terms to the minimum extent necessary to comply with the law and without affecting the validity or enforceability of the remainder.

The business is based in the Republic of Ireland and the currency is Euro. We can process directly in Euro only. If you have paid with a bank card based in another currency, you may be subject to transaction fees and exchange rates that are outside of our control. If you then need a refund, we will refund the amount required, but due to currency fluctuations and bank fees, you may not see the exact amount returned to your bank account.

If you cancel an order while it is in transit to you, you will be charged a minimum of €7.50 to cover the cost of the return shipping (this is for orders in Ireland). The cost will be higher outside of Ireland. We promise that we will only charge you the actual cost to us, there will be no further surcharge. This cost will be deducted from any refund due for the item(s) returned.

Enduro Bearings ACB 4545 4252 SS 42x52x7 45x45

Brand:Enduro Bearings

Code:EB9861

Product Description:

ACB 4545 4252 SS - 1-1/2 440C stainless steel Angular Contact Headset bearing (42mm x 52mm x 7mm; 45 x 45deg) - Angular-contact headset bearing featuring 440C stainless steel balls and races for superior corrosion protection.

This size bearing has been used as an upper bearing for Acros headsets that are designed specifically for aero cable routing, and is also know by part number AC4252

Not all stainless steel is created equal.

Enduro only uses 440C stainless steel balls and races to provide long life and superior corrosion resistance in applications and environments that may be less than ideal. 440C has the highest strength, hardness, and wear resistance of all the standard 440-series stainless alloys with high carbon content. As expected, it is also the most expensive of the 440 series alloys and requires multiple rounds of heat treatment and cryogenic treatments to achieve its superior mechanical properties. Though stainless steel has 20% less load capacity and is slightly softer than our standard 52100 chromium steel used in most of our bearings, stainless steel is an excellent alternative for use in wet conditions, if you wash your bike often, or where sweat can be a problem. Enduro Bearings also uses LLB type seals and CRC Marine Grease in these bearings to additionally water proof against the elements. Enduro 440C stainless headset bearings are the same bearings found in many popular headset brands, including those that carry a 110 year warranty.

The Enduro line of angular-contact headset bearings start with Black Oxide treated Chromium Steel races, steps up to full 440C stainless steel, and the top of the line is, lifetime-guaranteed, XD-15 aerospace-stainless (races and balls). They are always engineered with the largest balls possible, feature dual-lip seals riding in a micro-groove (labyrinth) and are filled 90% with high pressure water proof grease for the ultimate protection against sweat and the elements. Enduro Angular Contact (A/C) bearings are designed so all balls are evenly engaged to spread the force over a larger surface area, decreasing friction, minimizing wear and maximizing life.
