Brompton G-Line Tyre options

Having had my G-Line for several months now, I thought it was high time to share my thoughts on the delightful world of G-Line tyre options. 

When I first got my G-Line, it came fitted with the Brompton Schwalbe One tyres. Here is the lowdown on these:

Brompton Schwalbe One G-One Speed:

• ETRTO size 54-406 (20 x 2.10 inches)
• Maximum pressure: 55 psi
• Weight: about 493g each
• Price: around £60 a tyre
• No sidewall reflective strip (great for stealth, not so great for night riding)

• Foldable with a Kevlar bead
• Tubeless ready (for the adventurous souls out there)

I happily pedalled around, getting to know my G-Line better with these tyres fitted. The Schwalbe tyres were fantastic on rough terrain - ideal for dodging potholes and avoiding London’s infamous cobblestones. However, on the road, cycle paths, and compacted tracks, they felt a tad sluggish. I also found myself missing the reflective strip during my nocturnal escapades. Blending into the night isn’t always the best strategy!

So, I decided to swap them out for the Brompton Continental Contact Urban tyres, which I already had on my other Brompton bicycles. Here’s what they bring to the table:

Brompton Continental Contact Urban:

• ETRTO size 50-406 (20 x 2.00 inches)
• Maximum pressure: 73 psi
• Weight: about 420g each (a bit lighter, but still not a feather)
• Price: around £35 a tyre (a bargain, if you will)
• Reflective sidewall strip (hello, safety!)
• Wire bead

Almost immediately, my G-Line transformed into a much more nimble beast. The rolling resistance improved, and I could venture off-road without feeling like I was riding on a marshmallow. The confidence they gave me over some of London’s dreadful roads was much the same but longer rides became easier. Plus, they felt grippier on the tarmac - bonus!

I kept the Continental tyres on until a few weeks ago. With winter knocking at the door, I thought it wise to switch back to the Schwalbe tyres. I intended to keep them on until the end of February, but alas, I missed the Continental tyres and their ability to glide over the streets of London.

For most G-Line owners seeking a smoother ride over cobbles and potholes, with the occasional off-road jaunt, the Continentals are the way to go. Meanwhile, the Schwalbe tyres sit in a box, looking all pristine but neglected. I suspect they’ll remain there for the foreseeable future. If I were the bikepacking type, things might have turned out differently, but alas, I’m just a humble urban cyclist navigating the wilds of London! The Continental tyres are a much better option for me and they might be for you too.  

Until next time, stay safe out there people!
