Frame & Fork

Designed by Isla Rowntree. Hand‑built in the UK by Stayer Cycles. A carefully selected blend of Reynolds 853 and T45 steel. Small‑diameter tubes for comfort and compliance, which is enhanced by twin top tubes, which also facilitate the mid-step. 

Brakes & Bearings

Hope brakes and bearings — chosen for reliability, outstanding performance, long life and the reassurance that spares will be available almost indefinitely. 

Transmission

High‑wear parts — cassette, chain, rear mech — are intentionally inexpensive to replace. A square‑taper bottom bracket lasts years longer than modern standards, spins more freely thanks to larger ball bearings, and is cheap to replace when the time finally comes.

Why only 10 gears?

Because real world riding needs low gears, not a huge number of them. Fewer gears mean simpler setup, lower cost of ownership, and easier servicing — without compromising capability.

Why premium bearings & brakes but a “cheap” transmission?

Because the parts that matter most for safety, feel and longevity are premium. The parts that wear out fastest are deliberately affordable.

Cranks

Properly proportioned for each frame size — shorter than conventional.

Benefits include:

• More comfort, especially for smaller riders who are poorly catered for with “one size fits all” cranks
• Reduced risk of knee and hip injury for a long cycling life
• Lower bottom bracket for better standover
• Reduced “dead spot” for better traction on slippery climbs
• Improved saddle comfort
• Multiple studies show no loss of power

Control

• Bars are slightly wider and higher than dropped‑bar gravel setups
• Wide enough for control on tricky sections
• High enough to enjoy the view
• Narrow and low enough to tuck into a headwind
• Ergonomic grips with integrated mini bar‑ends offer multiple hand positions and spread pressure.

Saddle

Saddles are personal. We fit a well‑liked, good‑value starting point, or we can source your favourite, or supply the bike without a saddle so you can fit your own. 

Spec Options

Rosetta is designed for real‑world adventures, so Isla has personally tested a curated range of fully compatible travel accessories — the same kit she uses on her own bike for multi‑day trips.

Tyres

Choose the setup that suits your riding: road, gravel, or up to 57c MTB tyres for maximum versatility.

Rear Rack & Mudguards

A Tubus rear rack comes fitted with integrated off‑road mudguards. The whole unit removes easily as one piece — ideal for air travel or quick transitions.

Panniers

Ortlieb panniers: simple to pack, effortless to lift off, and tough enough to survive years of use. Take them straight into your digs at the end of the day.

Lighting & Power

A SON dynamo hub paired with Exposure lights provides “always‑ready” illumination and USB charging for your GPS or other devices — perfect for long days and remote routes.
