Dahon Speed Pro TT Folding Bike 27 Speed Rare Road Racing Commuter Like Brompton

The Dahon Speed Pro TT is a rare high-performance folding bike built to ride like a premium road machine rather than a casual commuter. This is the upgraded 7005 butted aluminium variant, noticeably lighter and stiffer than the older steel versions, with a distinctive mango-yellow finish and aggressive geometry designed for speed and distance. Unlike most folders that prioritise portability above all else, the Speed Pro TT combines a responsive aluminium frame with a 27-speed drivetrain and drops-bar handling, making it genuinely quick on both flat roads and climbs. The bike folds to a compact 36 x 66 x 80 centimetres in around 30 seconds, packing away easily into car boots, trains, or under your desk, yet when unfolded it delivers the precise handling and gear range you'd expect from a racing-focused road bike.

The drivetrain uses a SRAM DualDrive system combining a 3-speed internal hub with a 9-speed rear cassette, giving you the full 27-speed range of a triple-chainset road bike without the added complexity. The internal hub works particularly well for urban riding because you can shift gears whilst stationary in traffic, eliminating the frustration of chain drops that affects traditional derailleurs. Control comes via Shimano Tiagra STI integrated road levers mounted to distinctive Kinetix Pro TT bullhorn bars, letting you brake and shift without moving your hands from the bars. The aerodynamic tuck position works well for headwinds, whilst the bullhorn shape gives enough leverage for out-of-the-saddle climbing when you need to tackle steeper hills. Kinetix Pro lightweight 20-inch rims with paired spokes keep rotational weight down, whilst Schwalbe Durano high-pressure tyres roll efficiently on both road and light path surfaces. The Kore I-Beam saddle and post system keeps the rear end light without sacrificing comfort.

At approximately 9.7 to 10.3 kilograms, this aluminium frame is noticeably lighter than comparable steel folders, and the rigidity translates to confidence at speed. The patented V-Clamp forged hinge with GreaseFlow technology keeps the fold mechanism smooth and responsive after years of use. Shimano SPD clip-in pedals come fitted, making the bike instantly ready for riders who prefer clipless engagement. The bike is in very good cosmetic condition with a tight, solid hinge and smooth folding mechanism, though it does require a single replacement spoke in the rear wheel and trueing once fitted, and the Schwalbe Durano tyres and brake blocks are functional but getting older and would benefit from replacement to optimise performance.

The Speed Pro TT works well for fast multi-modal commutes mixing cycling with train or car travel, weekend touring, or longer urban rides where speed matters. Riders who regularly combine distances and need to stash the bike away between journeys will find it genuinely practical, whilst the performance-oriented geometry keeps things engaging rather than sluggish. It's suited to cyclists comfortable with road-style riding position and clip-in pedals, and who value outright speed in a folding platform. The original, unused Dahon factory carry bag with integrated storage pouch is included, making the bike train and office friendly whilst protecting both the frame and your car boot from damage. This is a genuine piece of high-end folding bike history from Dahon's golden era of performance engineering, and aluminium-frame Speed Pro TT models rarely come up for sale in this condition. Available for collection from Solihull, West Midlands, with UK courier shipping possible if arrangements are made with the buyer.
