An amazingly capable, versatile gravel road bike. Built for chasing horizons, exploring routes less travelled or accelerating your commute.
Gravel roads, out in the elements
Traction, handling, comfort
Clearance for big 45mm tires lets you push further into the rough stuff, and enjoy more grip and comfort on every ride.
Everything on the Topstone is designed for simplicity, ease of use and compatibility. Whether you're setting out on a big ride or taking the long way to work - less down time, more ride time.
Light, comfortable and precise. An all-new carbon fork features three mount bosses on each leg for maximizing cargo capacity, plus an easy mounting point for fenders - letting you ride any adventure in any condition.
Confident stability meets nimble agility. An extra long fork offset paired with a slack head angle keeps the steering light and lively, yet delivers unreal confidence at speed and in the rough stuff.
Built to accept an internally-routed 27.2 dropper seat post, which shouldn’t really be a surprise on a bike that's this off-road capable.
With plentiful gear and water bottle mounts on the frame and fork, Topstone is ready to load up and go long.
There are many contributing factors when it comes to picking the right size of bike. Whilst height provides perhaps the best indication of bike size it's not uncommon to size up, or size down depending rider flexibility, body shape, riding style and desired body position. Here at Billy Bilsland Cycles we understand the importance of bicycle fit, sizing and comfort in order to not only maximise enjoyment, but help significantly enhance performance and accomplish goals. Check the recommended height ranges below for a rough guideline, and if you have any queries don't hesitate to get in touch. For more information on our in depth bicycling fitting service click here.

If you require expedited/next day shipping, give us a call on 0141 552 0841 or drop us an email on firstname.lastname@example.org and we'll do our best to accommodate.
Every bike we sell is fully assembled and tested for safety by our trained mechanics. We then partly disassemble the bike and carefully re-pack to prepare for shipping.
Depending on the model, upon receipt you may be required to straighten and tighten the handlebars, reattach front wheel and attach the pedals. Please ensure that the pedals are greased and fitted correctly - the pedals will be marked L and R and have to be fitted to the left and right cranks respectively. Pedal do not come with every bike and need to be bough separately, especially on more high-end models. Please check when you are ordering.
There is a guide in the box telling you which tools you will need and the steps to follow. This will require some degree of mechanical skill to put together and can need some minor adjustments. The less confident you are in this field the more we'd recommend having it checked over by a professional mechanic.
We offer a standard 48Hr Service for courier shipping via Royal Mail for accessories, and APC Next Day for bike deliveries.
