The Zeppo with drop handlebars. A low-maintenance, all-weather bike for the commute and your Sunday ride, built up individually for each rider.

About the Z-Drop
The Z-Drop takes the best of the Zeppo and adds drop handlebars, creating a low-maintenance, all-weather bike that is ideal for both the commute and your Sunday ride. Tektro Hylex RS brake levers and a Jtek 8-speed bar-end shifter turn a standard Zeppo v.8 into a drop-bar machine.
Z-Drops are built up individually for each customer and can be modified to suit, so please allow 4 to 6 weeks for delivery.
Everything the Zeppo has
As with the standard Zeppo, the Z-Drop comes with:
No hill too big? We put this to the test by riding the Zeppo v.8 up Bealach na Ba, the UK’s biggest climb on public roads.

In brief
Every component was chosen to be robust, reliable and low maintenance.

The Gates carbon belt replaces the chain. No oil, no grease, and an average lifespan of around 30,000 km.

Shimano Nexus 8 internal gears with a Jtek bar-end shifter, and Tektro HD-T275 hydraulic discs with TRP Hylex levers for strong braking in all conditions.

Anti-theft Droid lights front and rear, and colour-matched alloy mudguards to keep your legs dry through the winter.

A 6061 alloy frame and fork keep the weight to around 11 kg, on 700c wheels with 32 mm Kenda tyres that suit city and country alike.

Drivetrain
The Gates carbon belt drivetrain means less time spent on maintenance and more time enjoying your new ride. No greasy trousers and no oily calf marks. A splash of water now and then is all the belt needs.
With bike spares often hard to come by, the Gates belt drive will be your best friend. Average lifespans are around 30,000 km, so you won’t have to worry about changing it for many years, if ever.
Gears and brakes
This is the business end of a bike, so we chose proven parts. Shifting is provided by a Shimano Nexus 8 hub paired with a Jtek MKII bar-end shifter: reliable, robust and low maintenance, with nothing to bend or clog.
Meanwhile, front and rear Tektro 275 hydraulic disc brakes with 160 mm rotors, paired with TRP Hylex levers, will have you stopping on a sixpence in all weathers.


Lights and mudguards
The Z-Drop has you covered. Alloy mudguards keep road spray off you and look right on the bike.
Our Droid anti-theft lights mean you’re always ready for the dark. These be-seen lights are designed to be left on the bike and, with up to 40 hours of battery life, they’ll keep you visible ride after ride.
Specifications
Sizing is simple: two sizes cover everyone from 5’3″ to 6’4″. Pick by height. The Z-Drop is unisex.
UK and Northern Ireland: £20 by APC overnight courier once your bike is built. As the Z-Drop has to fit in a box, the front wheel, handlebars and pedals need mounting on arrival. It’s a simple job and we send an instruction manual.

Caring for your Z-Drop
The best thing for all bikes is to keep them somewhere warm and dry. Clean your bike regularly, and keep an eye on bolts and components to make sure they are tight and working correctly.
The Z-Drop is designed to be low maintenance. The belt drive does not require oiling, but if it begins to squeak, clean it with water. Wax is also available to buy for belt drives. The internal gears are designed to need minimal intervention, but like everything else on your bike they will last longer if kept maintained. If you think something needs adjustment, take your bike to your local bike shop.
