Brompton shaves weight from the Superlight folder… and renames it P Line

London brand say updated model is faster to ride, lighter to carry, and easier to move around the city

Brompton has given its Superlight folding bike a new titanium rear frame and a compact gearing system… oh, and it’s now called the P Line.

The Superlight was introduced in 2005 as the lightweight option in Brompton’s range – the clue’s in the name! As well as being a benefit out on the road, light weight can be especially valuable when a folding bike has to be carried.

Now Brompton has evolved the Superlight into the P Line.

“Featuring an entirely new titanium rear frame and lightweight componentry, the meticulously engineered Brompton P Line weighs just 9.65kg, nearly 2kg less than the Brompton C Line model, delivering lightweight performance, folded and unfolded,” says Brompton.

The titanium rear frame and forks are said to be 700g lighter than Brompton’s all-steel equivalent while being just as strong.

“The naturally shock-absorbing titanium smooths out city roads and the redesigned suspension block maximises efficiency and responsiveness by shifting pedal power to improve control and handling performance,” says Brompton.

The new dual-locking seatpost system has two positions, fully down for storing or halfway up for rolling. The rolling wheels are larger (54mm) and lighter than previously.

“The patent-pending gearset is fine-tuned for city riding,” says Brompton. “The 4-speed system includes a 60g derailleur, cleverly engineered to fit inside the compact fold and providing a similar ratio to the 3-speed hub gear and 60% more than the 2-speed.”

You get 11, 13, 15 and 18-tooth sprockets and the choice of either a 50T or a 54T chainring.

The wheelset is new too. Brompton says that it’s the brand’s lightest, sturdiest ever and that it features a new rear hub designed to accommodate the 4-speed gearset.

The new Brompton P Line launches today and is available in Storm Grey and Midnight Black finishes from and accredited retailers. It is priced at £2,100.

It's a shame they didn't decide to make the main frame Ti too for maximum bling. You can already get them on Ali.

Given that the Ti rear triangle is in constant contact with a rubber bumper / shock absorber screwed to the frame, I doubt that anyone can credibly attest to its 'natural shock-absorbing ability' compared to the normal steel one.  Utter nonsense.

Interesting.  This appears to be Bromptoms first ever proper derailleur bike as opposed to the iffy 2 speed version.
