Giant SLR 1 40 Disc Rear

Hookless rim design enhances overall durability and offers a wider inner rim width without adding weight.

Optimized carbon layup features high-tensile strength carbon fiber placed at the most crucial points to provide stiff and lightweight wheels.

40mm Hookless Rim Profile provides added aerodynamic advantage.

Dynamic Balanced Lacing (DBL) technology makes a stiffer, more efficient wheel with outstanding power transfer. The enlarged DBL hub flange increases spoke bracing angles, boosting overall torsional/transmission and lateral stiffness for better power transfer.

2.8mm rim bead width enhances rim stiffness, for better support for tires when cornering.

Designed for high volume road tires, the 22.4mm wide inner rim width creates an increased actual tire contact patch, resulting in better traction and impact absorption for more confidence and improved ride feel.

Giant low friction hub with precision machined internals eliminates excessive bearing load, reducing bearing friction, lowering rolling resistance, and minimizing power loss.

Hookless Rim Design - Hookless rim design enhances overall durability, offers a wider inner rim width without adding extra weight and also helps create a more round tire shape providing superior grip and handling as well as added sidewall support when cornering. Additionally, without the rim hook to " push" the tire bead inward, hookless rim design offers a more seamless airflow between the tire and the sidewall of the rim, resulting in less drag and improved aero performance when compared to standard hook-type rims.

Optimized Carbon Lay-Up - Giant optimized reinforced layup places extra maximum-strength carbon fiber only where needed, creating a robust structure at minimal weight.

Dynamic Balanced Lacing - Since its introduction in 2015, Dynamic Balanced Lacing (DBL) has been the cornerstone of Giant WheelSystems. DBL ensures that spokes are set for optimal tension when under dynamic load, resulting in enhanced durability and pedalling efficiency. The enlarged DBL hub flange also increases the spoke bracing angles, which boosts overall torsional/transmission and lateral stiffness for better power transfer and more stable sprinting.

Low Friction Hub - Giant uses precision machined internals to eliminate the power loss that occurs through the pressure from the hub internals on the bearings, reducing friction and minimizing rolling resistance.

UK delivery

If your item is in stock and ordered before 12pm, we will do our best to despatch your order the day you place it. In busy times we tell you how long it will take us to process it.

The above does not apply to bikes, which we have to assemble and inspect before repacking for dispatch. Typically we try to have bike orders dispatched within 3-5 days, but in busier times it may take longer. In those cases we'll let you know of longer than expected delivery times.

Please bear in mind that we are closed on Wednesdays, so no items will be dispatched then.

Free postage over £40

For small items we use Royal Mail's 48 service which has a delivery time of typically 2-3 days from dispatch; though you do have the option to upgrade to 24 which is generally next-day from dispatch if you require your order sooner. Please note in some cases the item will need to be signed for, so please provide an address where someone will be in.

Orders of over £40 will qualify for free standard postage with Royal Mail 48. This may exclude certain bulky or awkward items which will be calculated automatically at the basket screen.

Bike shipping

When we send out a larger parcel such as a bike or trailer we use a next-day courier - usually either DPD or Parcelforce.

For these reasons please supply us with a delivery address where there will be someone in to sign for your parcel. If there is nobody in when the couriers call, they will leave a card. You can then phone them to arrange delivery for another day or collect your goods from your local depot (a photo ID with proof of address will be required).

How will my bike be delivered?

We fully assemble, safety check and inspect every bike as though you were going to ride it away from our showroom.

However, to get it back into a box suitable for a courier to handle, we have to remove the pedals, handlebar and usually the front wheel - so some minor reassembly is required when the bike is delivered to you.

Please bear in mind that you might need a 15mm spanner for the pedals (adult's bikes generally do not come with pedals included, so you may not need to worry about this), and 4mm, 5mm and 6mm allen/hex keys for the reassembly.

Outside the UK

Since Brexit it is no longer feasible for our website to have permanent shipping prices for international delivery. Instead, if there is an item you are interested in, please Contact Us with a full delivery address and we will quote for delivery.

All the prices on our website and catalogue are in pounds sterling and are inclusive of VAT, but VAT will be removed for international orders. Please bear in mind that you will likely have to pay your country's taxes, import duties and associated courier handling fees for any items.
