Brompton C-Line 12 speed in Matt Black with SuperRoll+ Rack

Season:2027

Brand:Brompton

Code:2027-C-LINE-BLAC-12R

The Brompton C Line 12 Speed is the choice for riders who love the simplicity and practicality of a Brompton but want the freedom to ride further and tackle more varied terrain. You still get everything that makes the C Line such a great everyday bike: a beautifully made steel frame, small 16-inch wheels, quick handling and Brompton's famously compact fold. The difference is the 12-speed gearing, which gives you a much wider range than the simpler 4-speed model.>

That extra range really comes into its own if your commute includes plenty of hills, you're carrying luggage or you simply want to use your Brompton for more than short trips across town. Lower gears make steeper climbs much more manageable, while the higher ratios give you plenty of scope when the road opens up.

Despite the extra gearing, there's no difference to the folded size. It's compact enough to take on the train, store beside your desk or keep in the hallway, yet capable enough that you won't necessarily want to stop riding when your commute finishes.

Sometimes a simple ride home can quickly involve a fairly serious hill if you take the scenic route, the C Line 12 Speed makes a lot of sense. It's the most versatile C Line for riders who want one folding bike to cover commuting, everyday transport and longer weekend rides.

Sizing Information

Choosing Your Brompton Handlebar Height

Brompton offers three handlebar heights – Low, Mid and High. Rather than being traditional bike sizes, these options change the height of your hands and therefore your riding position.

Low – Sporty
The lowest handlebar position creates a more forward-leaning, sporty riding position. It's a good choice if you prefer an efficient riding position, are used to road or fitness bikes, or simply like a lower front end.

Mid – Balanced
The versatile middle option offers a comfortable balance between sporty and upright. It's well suited to commuting, leisure riding and everyday use, and is a good starting point for many riders.

High – Upright
The highest handlebar position provides a more upright and relaxed riding position. It's particularly suitable if comfort is your priority, you prefer less forward lean, or you're a taller rider looking for additional handlebar height.

Remember, your height is only part of the equation. Two riders of the same height may prefer completely different handlebar positions depending on their proportions and riding style.

If you're unsure, visit us in store @ Avon Valley Cyclery in Bath to compare the different Brompton handlebar options and find the position that feels right for you.
