Boardman ADV 8.9 - Nearly New – XL 2025 - Gravel Bike
This ADV 8.9 gravel bike is rated as an Excellent Grade, which reflects that the bike is in very good condition and can be considered to have been 'pre-pedalled'. Having been lightly used, there are some signs of use on the bike. The only minor visible marks is the paint is flaked around the seat post collar.
To ensure this bike meets our high standards for quality, it has undergone a thorough inspection by our professional mechanics. As with all our bikes, it comes with a 12-month Tredz warranty, plus any additional manufacturer warranty which may apply.
Frame & Fork
A smooth welded 6061 alloy frame with butted tube profiles sits at the core of the ADV 8.9 adventure bike. To complement its clean aesthetic, the frames, thinned tubes, and carbon fork work together to reduce weight and improve ride quality.
In addition to its engaging and responsive handling, the ADV's versatility shines through. It boasts hidden mounts for full-length mudguards, fixings for a pannier rack, dropper post routing, bottle and storage fixings on the top tube, seat tube, downtube and fork legs.
Groupset
The Boardman ADV 8.9 is fitted with Shimano's dedicated gravel-specific GRX series groupset. A GRX 10-speed drivetrain that benefits from adventure-specific ergonomics and optimised gearing.
The double 30/46 tooth chainset and the 10-speed, 11-36 tooth cassette at the rear offer ample gear choices, allowing you to maintain power and speed on the flat while keeping cadence high on climbs.
Wheels & Tyres
The Boardman ADV alloy wheelset is tubeless ready, designed to be run tubeless .. less. All you need is sealant and valves!
Featuring Goodyear's 40mm gravel-specific Connector, the fast-rolling all-terrain tyre. Its versatile tread pattern delivers straight-line momentum while retaining grip.
Finishing Kit
Flared alloy handlebars allow for optimal ergonomic hand position on the hoods, more control while in the drops, and facilitate more frontal space to carry additional luggage.
Comfort is key whether you're rolling over pot-holed lanes or heading off the beaten track. A wider rear section and pressure relief channel have the right balance of comfort and firmness for an effective pedalling platform.
Occasionally, without notice, manufacturers change product design and/or specifications.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimetres for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but are like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the Mountain bike column.
