- The LEONARDO:PURA is a stripped-back titanium performance bike built for riders who value mechanical purity, efficiency, and long-term durability. Constructed from a full titanium frame, it offers an exceptional strength-to-weight ratio, inherent corrosion resistance, and natural vibration damping, delivering a ride that feels smooth, responsive, and enduring across daily use and extended mileage.
- At the heart of the bike is a Gates Carbon Drive belt system, replacing the traditional chain with a clean, silent, and virtually maintenance-free drivetrain. Engineered for longevity and consistent performance in all conditions, the belt drive eliminates grease, reduces wear, and ensures a refined riding experience ideally suited to urban environments.
- The LEONARDO:PURA is built around versatility without complexity. A flip-flop rear hub allows riders to switch between single-speed and fixed-gear configurations, while an optional two-speed internal system expands gearing range without compromising the bike’s minimalist design. This modular drivetrain approach provides adaptability for varied terrain while preserving a clean, uncluttered aesthetic.
- Designed with practical performance in mind, the frame incorporates mounts for mudguards and racks, alongside serviceable component choices that prioritise reliability and ease of ownership. Built to order in London, the LEONARDO:PURA embodies a clear philosophy: precision engineering, low maintenance, and a direct, unfiltered connection between rider and machine.

- Precision‑engineered drivetrain solution designed for riders who demand both simplicity and performance. At its heart lies an ultra‑thin (just 10 mm) planetary gearbox that neatly integrates with your chainring, with no bulky mechanisms, no extra cables or derailleurs.
- Shifting is ingeniously simple: a gentle heel tap on the side button lets you engage the alternative ratio, either a 1 : 1.65 overdrive in the Speed‑Drive version for higher speeds.
- Built with premium materials and designed to take full torque in both pedalling directions, it’s equally compatible with fixed‑gear and coaster‑brake setups. This compact, low‑maintenance gearbox gives you a minimalist look with maximised versatility.
- Change gear with a simple kick of the heel on the side buttons, while standing still or under heavy load.
- Low maintenance.
- No cables, levers or derailleurs.
- High efficiency, high quality materials, ensure great longevity.
- Symmetrical clutch allows full torque in both pedalling directions, for coaster brakes and fixed-gear bikes without a rear brake.
- The optional EASY-SHIFT plates, available on request, cover the whole crank arms and allow for shifting by pushing on a larger area, best for clip-in pedals.
- SPEED-DRIVE ratios: 1x direct-drive and 1.65x overdrive.

Great value speakers for a beginner audiophile
Size: 4” Woofer
Fantastic sound quality to my ears, got these used “mint” for 179 and that was a steal, they were never even opened. They feel solid and well made, they’re heavy for the size which makes them feel of a higher quality. Very happy with my purchase

compact surrounds that blend well with the right setup
Size: 4” Woofer
I picked up the Klipsch R‑40M as part of a full 5.1 system built around the R‑50M fronts and the R‑50C center. My original plan was to use another pair of R‑50M speakers in the back, but they simply didn’t fit in the rear cabinet space I have. The R‑40M ended up being the only model that fit comfortably, so they became my surround channels.
In terms of build quality, they feel solid and consistent with the rest of the Reference Next‑Gen line. The copper woofers and updated horn design give them the same visual identity as the larger models, which helps the whole system look cohesive. They’re compact enough to place in tighter spaces without compromising too much on performance.
Sonically, the R‑40M does a respectable job as a surround speaker. Effects are clear, directional cues are easy to follow, and they integrate smoothly with the more powerful R‑50M fronts. That said, they are noticeably less powerful than the R‑50M, so you need to spend a little time balancing your levels. Once I bumped their channel trim a bit and adjusted the distance settings, the rear soundstage locked in nicely and felt much more even.
They won’t deliver the same fullness or dynamic punch as the larger models, but for rear channels that’s usually not a deal breaker. What matters is clarity and consistency, and the R‑40M handles both well. Movies with active surround mixes feel immersive, and ambient effects wrap around the room without calling attention to the speakers themselves.
If you’re building a system where space is limited in the back, the R‑40M is a practical and capable choice. Just be prepared to fine tune your calibration so they match the output of the bigger speakers up front. Once dialed in, they round out a 5.1 setup very effectively.
