90-Day UK Returns for all items

We want you to be 100% satisfied with your shopping experience at Rutland Cycling, so we offer a 90-day exchange or refund on any unused item (within the UK).

We've chosen to offer products at the very lowest prices, rather than provide a free returns service. If you do need to return an item, we provide printable postage labels and collection services at a small cost for all items - including bicycles.

See our full Returns policy.

Description

Season :

Code : ASRNS5DMAT

Brand : Renthal

Weight : 2KG

Renthal's revolutionary new Duo Stem combines high strength with ultra-low weight with a unique horizontal divide allowing the stem to be machined to the lightest weight possible without affecting performance and durability.

In addition to shaving massive amounts of weight over a standard stem, this unique design also creates an uninterrupted U-Shape clamping areas which reduces stress risers which can cause your handlebar to fail.

CNC Machined

Renthal's Duo Stem is fully CNC machined from a solid billet of 6082 T6 Aluminium, specifically chosen for the highest strength to weight ratio.

U-Shape Clamp

Uninterrupted U-Shape clamping area cradles the underside of your handlebar, eliminating stress risers that can lead to bar failure.

Horizontally Divided

Unique to the Renthal Duo Stem, the body is horizontally divided to allow access to core of the stem to remove the maximum amount of material possible whilst retaining strength and stiffness.

High Quality Finish

Both halves of the Renthal Duo Stem are anodised and laser marked to provide a high quality and durable finish that keeps your stem looking good.

    I bought the 40mm reach and use on a Ibis Mojo HD... The stem is light, great quality, stiff and strong. A little tricky to set up initially. I swapped the standard screws for Ti to lose a little more mass.

    Pre-Order

    With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

    You 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 and get it sent out 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 Dates

    Estimated Delivery 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 Dates provided on product pages.
