The G Line Brompton

[Drago]

A shame to hear that. I think you could use lighter and thinner tyres to make it roll a bit easier and quicker. Though it is marketed as a gravel bike is it not?
Are the brakes disk or hydraulic?

I believe they do an option with more road oriented tyres, but I'm told it doesn't make them feel any livelier.

The version I test rode was fitted with Conti Urban Contacts in 20” x 2.2"; 50x 406

According to the Conti website, you can also get 1.6 and 1.25.
