2024 Brompton T Line 12-Speed: Titanium Folding Bike First Look

Cycling · Published 3/11/2024 ·

Lighter is always better when it comes to anything you ride.

The catch is that it gets expensive.

I just picked up a 2024 Brompton T Line with the stock 12-speed setup. The photos show the T Line getting its pre-delivery service.

The main materials are titanium and carbon.

I applied PPF to a few spots to head off the scratches you can see coming.

I removed the rear reflector. I always ride with my Garmin Varia 715 switched on, so I rely on its light to deal with cars coming up from behind.

The BROMPTON decal is no longer a sticker — it’s now laser-engraved. Stickers tend to get damaged with use, so this seems like a good change. That said, engraving probably isn’t feasible on the regular lineup. If you tried to laser-engrave over colored paint, I imagine it would just smear or burn away. They’d need a different approach there. The 2024 Brompton T Line 12-speed has a bare, unpainted titanium frame throughout, which is why laser engraving works on it.

I moved over the Lezyne pump I’d been using on my previous P Line. This time around I didn’t remove the mudguards. Mudguards really do get in the way when you want a nice, brisk ride — they create a lot of drag, too. But without them, you become incredibly vulnerable to shifting problems and to the bike getting filthy. Honestly, it ends up dirtier than a road bike that never had mudguards in the first place, and the shifting troubles are just as bad. So I’m leaving it in stock condition.

It fits nicely in the trunk.

In stock 12-speed form it’s 8.8kg. Once I swap the grips and add pedals, a headlight, the rear radar, and the Garmin speedometer, I’ll probably be riding at around 9.1–9.2kg. I wanted something I could ride like a road bike — keeping my cadence up through multiple gears — but that I could also fold and store indoors or in the car trunk. After a lot of deliberation, I bought it.

Pros: very light for a Brompton; pulls off 12 speeds with a combination of internal and external gears; the internal hub isn’t resistance-free, but there’s less drag than I expected — almost none, really.

Cons: expensive — way too expensive.

I’ll see you out on the Han River. ^^

Thank you.
