New for the 2021 model year, the ADV 8.6 is Boardman’s entry level Adventure bike. Retaining many of the amazing features of the outgoing ADV 8.8, its comfortable geometry and go-anywhere design mean you can count on it no matter where you plan to ride.The new 2021 Boardman ADV 8.6 Adventure Bike uses a light but strong aluminium frame and tapered carbon fork which combine for great comfort on and off road. Adventure specific geometry gives a more upright position which is more forgiving when the going gets bumpy, a low bottom bracket adds stability whilst Schwalbe G-One 38mm tubeless ready tyres have plenty of grip when its needed. Shimano Sora gearing with an “adventure compact” 48/32 chainset and 11-32T cassette ensure the right gear is always at your fingertips whether you are climbing or descending and Tektro disc brakes enable you to stop in you tracks no matter the surface.Boardman ADV 8.6 specifics: Gears: Shimano Sora 18-speed gearing with an 11-32T cassette offer an excellent range to tackle all terrains, Frame: Lightweight Alloy with smooth welds for clean aesthetics , Forks: Full Carbon tapered forks offer low weight and precise steering control, Brakes: Tektro disc brakes for controlled and powerful stopping, Wheels: Boardman wheels and 38mm Schwalbe tubeless-ready tyres for balanced performance and comfort on and off road,.More About The New Boardman ADV 8.6 Adventure BikeLightweight frame and forkThe 2021 ADV 8.6 is built on an Adventure specific, alloy frame for easy handling. It varies from Boardman’s road frames in a number of ways: The geometry is designed with off road riding in mind, and id designed so that the rider sits in a more upright position meaning you can spend hours in the saddle in comfort. The bottom bracket, where the pedal arms meet, is lower which drops the centre of mass, helping the bike to feel extremely stable in all conditions. The ADV 8.6 also features a full carbon, tapered fork which is wider where the forks meet the frame and therefore adds steering precision and stability.Robust Sora Disc Brake GroupsetBenefitting from Shimano’s trickle-down Technology Programme the R3000 Sora groupset that features on the ADV 8.6 has the responsiveness and feel of a more premium set up. On the ADV 8.6 the 11-32T rear cassette is paired with a sub-compact 48/32T chainset which combine to offer an excellent range of gears, even if you’re loaded up. And when you are carrying extra cargo the Tektro mechanical disc brake will ensure that you come to a fast and controlled stop, no matter the weather.The little things that matterWith Chris Boardman as Chairman of the company, Boardman have a wealth of experience to draw on and are always looking at the fine details when developing bikes. Using data from hundreds of bike fits and insight from bike fit experts, they have made simple changes to the touch points of the bikes. They’ve worked to develop a range of saddles using advanced pressure mapping and real-world testing to make sure any saddle on a Boardman bike is going to suit the majority of people riding it. The ADV models went through exhaustive testing to find the perfect combination of bars and stem to give controlled yet responsive handling meaning you’ll get a confidence inspiring feel whether on your daily commute or hitting the trails.Versatile tyresWith a 38mm width, Addix compound and good tread pattern the Schwalbe G-One Allround offers great grip for off-road tracks and dry trail sections but has a low rolling resistance so that speed is not overly compromised on the road. The extra width offered over a traditional road tyre allows for lower tyre pressure and better comfort both on and off road, and Schwalbe’s Raceguard layering reduces the risk of punctures.

The ADV 8.9 might just be the best value for money bike we have ever made, given that it’s essentially 2 bikes for the price of 1. It’s equally at home exploring hidden bridleways and fire roads as it is clocking up miles on potholed commutes or long sportives.A triple-butted 6061 aluminium frame with hidden welds, and a full carbon fork with tapered steerer, with thru-axles at both ends, make up the heart of the bike. Blending comfort and control without compromising efficiency or sacrificing precise handling – this is an ideal platform to build the perfect all-road bike around.The ADV takes inspiration from the MTB world with its geometry – trail bikes have become more capable as top tubes have got longer and slacker, and this is passed onto the ADV. We’ve kept the top tubes long and slackened the head angle versus our road bikes, which gives a confidence-inspiring ride on loose surfaces, but without compromising body position for road riding. A slightly taller front end and a shortened stem keep the bars close to hand and sharpen up steering response.Shimano’s 2x10 speed GRX adventure bike groupset has a wide range of gears with a 48-32 FSA chainset and 11-36 cassette, perfect for steep climbs. The GRX hydraulic brake levers are designed to offer better power braking from the tops and are fitted to a flared handlebar that is wider at the bottom than the top, giving great control when you’re descending on the drops. With 38mm Schwalbe G-One tubeless-ready tyres, there’s plenty of fast-rolling grip available too.Completing the package are mounts for full-length mudguards and a pannier rack, adding the versatility for commuting, touring or winter road riding on top of the off-road smiles the ADV 8.9 delivers.Light but strong aluminium frame and tapered carbon fork give great comfort and control on and off-road,10 Speed Shimano GRX groupset is designed specifically for adventure riding with wide gear range and a “clutch” rear mech to limit chain slap,Powerful Shimano Hydraulic disc brakes ensure maximum control in all conditions,Schwalbe G-One All Round 38mm tyres combine off-road grip, low rolling resistance and added comfort – perfect for exploring anywhere,Boardman ADV wheels and Schwalbe tyres are tubeless-ready – easy to upgrade to run without tubes,Mudguard and pannier rack mounts offer additional flexibility.

Famous for its craftmanship on road and track wheels, Campagnolo has applied its expertise to the gravel market. The Levante wheelset is reactive, versatile and durable they are made for Point and Shoot handling. Its first all-gravel wheelset - Levante, is named after the Easterly wind of the Mediterranean, Levante brings a host of proven Campagnolo technologies to the gravel scene. Gravel Wheelset with Handmade Ultra-Light Carbon Rims Stiff for climbing, light for handling and compliant for descending, Levante benefits from Campagnolo’s Handmade Ultra-Light Carbon (H.U.L.C) which is used in the rim construction and is the result of extensive development over decades of in-house carbon fibre moulding. This enables Campagnolo’s engineers to optimise the usage of both fibre and bonding resin for the perfect blend of strength, stiffness and lightweight. All of this combines to create an awe-inspiring ride feel without undue harshness and a wheelset that weighs in at just 1485g. The Levante rim sports the beautiful mirror-like finish aptly named Campagnolo Luxury (C-LUX). This finish is so pristinely smooth that it doesn’t require any additional lacquer, saving valuable grams across the wheelset. The Levante pairs this stunning finish with durable laser-etched rim graphics capable of withstanding even the most demanding of gravel rides. Campagnolo’s consideration for durability is deeply rooted in the Levante Wheelset, and the premium H.U.L.C construction combined with an asymmetric offset on the rim provides a strong and balanced wheel that can take the rough with the smooth. A simple cup and cone hub system meanwhile ensures ease of servicing and external nipples allow for tool-free on-the-go spoke tensioning if needed. Two-Way Fit Technology for Tubeless and Clincher Not only is the Levante wheelset durable but it’s versatile too. Campagnolo’s two-way fit rim profile ensures tubeless and clincher compatibility while the 25mm internal rim width can accommodate 38mm to 78mm tyres (1.5-3.0”). The wheelset’s Mini-Hook has been designed specifically for the Levante rim and matches the E.T.R.T.O Clincher and Tubeless requirements using the most minimal dimension possible. As a result, the slight hook provides a perfect match between the tyre and rim. This means a large contact area with the terrain, increasing grip and comfort at lower pressures. Campagnolo’s Next 3 Ways (N3W) option is compatible with Campagnolo 11, 12 and 13-speed cassettes. The wheelset is also available with freehub bodies for Shimano HG and SRAM XDR (please choose the option from the menu). The Campagnolo Levante 2-Way Fit Carbon Gravel Wheelset is a perfect choice of upgrade for conquering everything from epic weekend backroad adventures to racing for the finish line.
