Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

Season:2027

Brand:Diamant

Code:72696RED

The Diamant Mahon Style Pro Midstep is a premium trekking bike designed to combine everyday practicality with smooth, low-maintenance performance. Its Alpha Smooth Aluminium frame uses a midstep design for convenient access, with internal cable routing and a rigid alloy touring fork equipped with accessory mounts.

Shimano Alfine 11-speed internal hub gearing is paired with a Gates CDN CenterTrack belt drive, keeping the drivetrain clean and straightforward while providing a broad choice of gears for everyday journeys. Wide 700x42c Bontrager Girona Comp tyres feature puncture protection and reflective detailing for versatile urban and trekking use.

A Shimano dynamo hub powers the integrated lighting, removing the need to routinely recharge separate lights. Shimano MT200 hydraulic disc brakes provide dependable stopping control, while ergonomic grips, an adjustable stem and a Brooks Cambium C19 Special saddle complete the comfort-focused specification.

Features & Benefits:

  • Smooth, Low-Maintenance Drivetrain: Shimano Alfine 11-speed internal hub gearing and a Gates CDN belt drive provide a clean drivetrain with fewer exposed components than a conventional derailleur system.
