Van Rysel RCR-R PRO Dura-Ace Di2 2025 £10,000 £7,999 (save 20%)
This is one of the most talked-about bikes of 2025, combining low weight and aerodynamic frame features in one race-ready package.
Ridden at the highest level by the Decathlon AG2R La Mondiale team, the Van Rysel RCR-R PRO is proven in the world's toughest road races.
This model features Shimano's flagship Dura-Ace Di2 groupset and SwissSide Hadron Ultimate 500 Carbon Tubeless aero wheels.
Silca Italian Army Knife Venti 20-Piece Multi-Tool £55 £44 (save 20%)
This multi-tool from boutique brand Silca combines beautiful design with every tool you'll need.
There are 20 hardened steel tools, including a chain tool with a magnetic slide-lock design for increased length and ease of use. There's also a hidden storage area for a spare chain link.
The tool is coated with high-grip chrome plating and weighs 172g.
Specialized Mondo TLR Road Tyre £55 £40 (save 27%)
The Mondo is Specialized's endurance road tyre – and one that's designed to be quick, too. So much so, it was used in the Spring Classics by Specialized's sponsored WorldTour teams.
The Mondo uses the brand's Gripton T2/T5 dual-compound construction to balance speed, grip and durability.
It's available in three sizes: 700x28x, 700x32c and 700x35c.
Wahoo KICKR CORE Smart Turbo Trainer With Cassette £499 £404 (save 19%)
It's indoor training session and the Wahoo KICKR CORE has everything you need to get started. It's a direct-drive smart trainer, meaning the resistance will automatically change when the gradient rises or you start an interval on an indoor training app.
The KICKR CORE can simulate gradients of up to 16 per cent, while also being capable of measuring power to an accuracy of two per cent.
It will also be supplied with a cassette, so you just need to hop on your bike to get going.
Trek CarBack Radar Rear Light £170 £99 (save 42%)
The CarBack from Trek combines a 90-lumen rear light with radar technology to detect rear-approaching vehicles from up to 240m. The light then delivers audio and visual alerts through your paired GPS unit.
There are four modes to choose from: Day Flash (90 lumens), Day Steady (25 lumens), Night Steady (5 lumens) and Night Flash (5 lumens).
Trek says the Day Flash mode is visible from distances of up to 2km, making this a light that features the latest in safety tech.
Shokz OpenRun Pro 2 Mini wireless headphones £169 £143 (save 15%)
With turbo season upon us, now's the time to get set up to keep yourself occupied indoors.
The Shokz OpenRunPro 2 bone conduction headphones are a lot more comfortable than in-ear and over-ear designs when training. They will run for up to 12 hours and five minutes of charging will give you 2.5 hours of use.
Sigma Sports also has a discount on the standard OpenRun headphones.
Selle San Marco AllRoad Supercomfort Racing Saddle £160 £116 (save 28%)
If your gravel bike needs a saddle upgrade, this Selle San Marco option includes variable-density extra-dense padding and a wide cut-out. The brand says this adapts to your saddle movement and ensures long-distance comfort.
The claimed weight is 213g, and there are three colours on offer to match your gravel bike. Sigma Sports has a range of other saddles on offer from Prologo, Selle Italia, Fizik and more.
SunGod Ultras Photochromic sunglasses £190 £149 (save 22%)
The SunGod Ultras feature a frameless lens for good peripheral vision, also offering a low 26g weight. Three nosepieces allow you to tailor the fit so they shouldn't slip around when riding.
The photochromic lens is a great option for off-season riding, offering between 34 per cent and 79 per cent light transmission, to see you through sun and shade on sunnier winter days, as well as gloomy ones.
There are other SunGod sunnies and lens options on offer, as well as discounted sunglasses from Oakley, 100% and more.
Scope Artec 8.T wheelset £3,499 £2,974 (save 15%)
Scope claims its Artec wheels offer best-in-class aerodynamics thanks to its fishscale-like surface finish, in a wheelset that weighs only 1,384g in this 85mm depth. The 23mm hookless internal rim width will support wider tyres for lower rolling resistance, and the carbon spokes contribute to the low weight.
If you're after a choice of flashy wheel upgrades, Sigma Sports has a similar discount on Princeton CarbonWorks Grit and Peak wheels.
SeaSucker Mini Bomber 2 bike carrier £550 £440 (save 20%)
Transporting your bike on a car usually involves clamping hardware to your vehicle.
The Seasucker bike racks do away with that, using large suction cups to attach to your car roof, so there's much less hardware to stash away when not in use.
It works via the same suction cups as used by glazers to move large panes of glass and high-rise window cleaners to keep them aloft.
We've tested it and it really does work. Sigma Sports has the three-bike model with the same discount as this two-bike rack.
Lazer Z1 KinetiCore helmet £230 £159 (save 31%)
Lazer updated its classic Z1 helmet in 2024, adding its KinetiCore crumple zones for additional rotational impact protection. The update also removed weight, with our size-M helmet coming in at 236g.
Along with the large vents, the KinetiCore treatment in the shell makes the Z1 KinetiCore a very well-vented helmet, too. Sigma Sports has a range of sizes and colours in stock.
Specialized Aethos Expert road bike £5,500 £3,499 (save 36%)
The arrival of the updated Aethos 2 means the original Aethos is at a discount. If you can bear to have your brake cables exposed – the horror – this SRAM Rival AXS spec gets you a similarly lightweight frame to the Aethos 2, but for £2,000 less cash than the updated bike.
Sigma Sports has sizes from 54cm up available in a couple of colours, both equipped with a Rival power meter and Roval C38 carbon wheels paired with 28mm S-Works Turbo tyres.
Challenge Gravine XP Handmade TR gravel tyre £88 £59 (save 33%)
Available in 40mm and 45mm widths, Challenge's gravel tyres' aggressive, spaced-out lugs are designed for grip in muddy conditions or over rocks, so they're ideal for the coming winter.
The tyre is built on a 260 tpi casing for a supple ride feel and is compatible with hookless rims. There's bead-to-bead puncture protection and Challenge's high-durometer rubber compound for good wear resistance and low rolling resistance.
Fumpa electric bike pump £139 £112 (save 19%)
We've been blown away by electric pumps here at BikeRadar, to the extent that Warren has thrown away his mini-pump collection. Fumpa was the original portable electric pump maker and this pump will get a 25c tyre up to 100psi in around 25 seconds.
There's a built-in pressure gauge and the capacity to inflate five or six tyres on a charge, with USB-C fast charging replenishing the battery in just one hour. The more portable miniFumpa is also discounted in the sale.
Lezyne Power Pro 115+ StVZO front light £100 £69 (save 31%)
At 310 lumens, Lezyne's alloy front light puts out more illumination than its name suggests. It can run for up to 4.5 hours in peak mode, or 27 hours in economy mode, so runtimes are better than some lights with greater headline output.
What's more, the light is StVZO-compliant, so its lens is designed not to dazzle and annoy oncoming traffic, but direct the beam downwards for good illumination of the road ahead.
