Giant SLR 1 42 Carbon Disc Brake Hookless Wheels

Season:2022

Brand:Giant

Code:21slr142discwheelsetBLK

The new Giant SLR 1 42 and SLR 1 42 Disc WheelSystems draw on the technologies of their premium partner brand CADEX.

They are a cost effective option for those looking to upgrade to a modern, quality carbon wheelset and honestly priced as well. Featuring hookless rim design and optimized carbon layup to ensure a robust yet lightweight structure, contemporary wider inner width, as well as low friction hubs offering low rolling resistance and Dynamic Balanced Lacing (DBL) technology to maintain maximum power efficiency, the SLR 1 42 and SLR 1 42 Disc bring outstanding performance with no compromise.

Hookless designs are not that common in road as yet, largely because tubeless tyre standards are anything but consistent so tyres blowing off of rims is a risk - particularly at higher pressures. Giant are at the forefront of hookless tech - along with ENVE.
Since Giant's Cadex range uses the technology and they already have an excellent range of consistently good fitting tubeless tyres, it was a given that the Giant core range would benefit from the tech. It has happened quickly and this is exactly what the industry needs.

Proper, consistent Tubeless at accessible prices.

Giant's hookless design provides the best airflow transition from the tyre to the sidewall of the rim, resulting in reduced aerodynamic loss when compared to standard hook bead rims. The design and construction maximises aerodynamics and durability. Significant reductions in front and side drag ensure that these wheels are extremely fast, yet remain stable in shifting winds.

The spokes are also laced into the rim using race-proven Dynamic Balanced Lacing (DBL) technology that varies tension not only between drive and non-driveside spokes, but within the drive side itself. This ensures that the spokes are set for optimal tension when under dynamic pedalling force versus when static, resulting in superior transmission stiffness and efficiency.

  • Low friction hub with precision machined internals eliminates excessive bearing load, reducing bearing friction, lowering rolling resistance and minimising power loss
  • Dynamic Balanced Lacing (DBL) ensures spokes are set for optimal tension when pedalling, resulting in enhanced durability and transmission efficiency
  • The enlarged DBL hub flange increases spoke bracing angles, boosting overall torsional/transmission and lateral stiffness for better power transfer
  • 42mm deep all-round rim profile with an updated inner width offers better support for today’s higher volume road tyres

  • NOTE : Since Cadex and Giant are manufactured by the same company (Giant), the following CADEX buyer's guide also holds true for Giant's new Hookless Road Wheels (2021 Onwards)

    Like any modern tubeless system, the tolerances of the tyre bead diameter and hookless rim bead seat diameters must be carefully calibrated in order to create an airtight seal that will allow the tyre to stay on the rim and the rider to slow to a safe stop in case of puncture. If the tyre bead diameter is too large, it will not match the rim bead seat diameter. Likewise, if the bead material isn’t strong or stiff enough under high pressure loads, the tyre bead will stretch over time and it will lose its original diameter.
    If rim manufacturers do not work directly with tyre manufacturers when designing new hookless rims, tolerances and bead materials can vary. This can make it difficult to pair tyres and hookless rims from different manufacturers.
    WHAT SETS CADEX APART?
    Rather than using a Kevlar-only bead, which can stretch over time and compromise the tyre bead diameter, CADEX / GIANT tyres feature a carbon and Kevlar composite bead that’s strong enough to avoid stretching under heavy loads. This, combined with accurately defined tyre and rim bead seat diameters, tested at pressures up to 150psi, guarantee dependable air and tyre retention.
    WHAT PRESSURE AND TYRES CAN I USE?

    TYRE PRESSURE
    No matter the type of rims or tyres you are using, never exceed the maximum pressure stated on the rim or tyre. Always follow the lower of the two maximum recommended pressures.
    TYRE COMPATIBILITY
    CADEX tubeless tyres are always the best match for CADEX Tubeless WheelSystems as they are designed in tandem. However, should you choose to use a non-CADEX tyre, there is a CADEX approved list of tyres that have been tested to be 100% compatible with CADEX rims.
    At the time of writing (16/03/22) the list is restricted to Giant Gavia tyres and of course Cadex's own Race tyre range. which are exceptional - as well as a select few others that can be viewed using the link above.

    For tyres not on the CADEX Approved Tyre List, CADEX are working continually with manufacturers so updates can be made to approve them. However, be aware that if you choose to use a tyre that is not on the CADEX Approved Tyre List, you do so at your own risk, and we cannot guarantee that the tyre will function correctly and safely with the CADEX Tubeless WheelSystem featuring a hookless bead.
    WHAT TYRES SHOULD I NOT USE?

    The following tyres have failed the CADEX test protocol and currently do not function properly with CADEX hookless WheelSystems:

    VITTORIA RUBINO PRO TLR 25C

    VITTORIA CORSA TLR 25C

    CONTINENTAL GP5000 TL 25C
    (Please note that the Continental GP5000 S TR tyre is apt for use on hookless rims and is a different tyre from the previous generation Continental GP5000 TL tyre. Please also note that as per Continental's specifications on rim inner width, the Continental GP5000 S TR in size 700x25C is only apt for use on the CADEX 42 and CADEX 42 Disc WheelSystems)

    PIRELLI CINTURATO 24C 26C


    For tyres that have failed the CADEX test protocol, CADEX is working with the tyre brands so updates can be made to make them ready for CADEX hookless rims as soon as possible.

    Please be aware that if you choose to use a tyre with an indicated maximum pressure above 72.5psi (5 bar) that is not on the list of tyres that have passed the CADEX test protocol, YOU DO SO AT YOUR OWN RISK, as the tyre may not function properly with the CADEX hookless WheelSystem.

    If the maximum pressure indicated on the sidewall of the tyre is below 72.5psi (5 bar) and the tyre is hookless rim compatible as per the tyre manufacturer’s recommendation, the tyre can be used with CADEX hookless WheelSystems and does not have to appear on the “WHAT TYRES CAN I USE?” chart.
    If necessary, you may use an inner tube on a CADEX rim, so long as the tyre you are using is on the CADEX Approved Tyre List. However, please note that CADEX rims are designed to perform best when set up as tubeless and used without an inner tube.
    Technical Information
    SLR 1 HOOKLESS RIM DESIGN BENEFITS

    LIGHTWEIGHT PERFORMANCE
    Compared with hook-type rims, Giant’s new hookless design has a wider inner rim width, allowing a smaller, lighter tyre to have the same volume as a larger, heavier tire, resulting in a lighter overall weight.

    ENHANCED DURABILITY

    Giant’s hookless rim design is realised through an innovative manufacturing process that results in a more continuous carbon fiber structure. This process enhances durability and increases impact resistance with no weight penalty.

    CONFIDENT HANDLING

    Hookless rims help create a more round tyre shape that provides superior grip and handling as well as added sidewall support when cornering.

    AERO ADVANTAGE

    Without the rim hook to “push” the tyre bead inward, Giant's 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 rim

    OPTIMIZED CARBON LAYUP

    Through high-tensile strength carbon fiber placed at the most crucial points and tested with Finite Element Analysis (FEA), Giant’s engineers overcame the challenge of building wheels that are as durable as they are lightweight. With industry leading stiffness, ride compliance and strength all at the lightest weight possible, the new SLR WheelSystems are fast and strong.
