A classic Brompton folding bike, it serves one purpose, which is for short trips...but does it have one purpose? Can we turn our GCN Brompton into a MT-Brompton? We have no idea if it's a good idea but Alex is on a mission to find out. It's time to build!

Who would build an off road Brompton? 🤘

I am surprised they don't offer one stock. After all these years they don't offer a more heavy duty version with off-road tires. Bike Friday has done this for quite some time now.

@codak29 9 месяцев назад

The Brompton folds to enable multimodal transit. Who is taking a train to the trail? IMO it's just a less effective mountain bike.

I had ordered a kit from him. I do not recommend these parts. I was really exited about that, but the quality was terrible, and the communication even worst. The Brompton parts I had ordered came extremely late. He said 2-3 weeks lead time, but I only got it after 2.5 months, without an apology or anything. I got an incomplete order anyway, but he did not really cared about that, he did not send the forgotten part after the fact. The paint job on the parts were terrible, really, it flaked down under every screw, it is full of scratches now. He said he did not do the paint job himself. And that is all, it feels like he do not care about customers. The parts are expensive, but the quality is not good at all. My rear triangle was even skewed in the mounting consoles. I was expecting a quality hand made product with a personal touch, but I did not get that at all. (The picture is just for an example, it flaked down everywhere...)

@finncarlbomholtsrensen1188 7 месяцев назад

You are able to buy Eastern, Brompton-like parts also from titanium and a fork and triangle intended for a Disc Brake. I would definitely prefer a "Hydraulic Disc Brake" in front, and not waste my time and money for the back, as it is easily able to block the wheel at any time, with the ordinary brake! My now much less than 2019 SuperlightM6LXBrompton for now weighs 8,5 kilo (mudguards), and still falling, with a little more work on my mudguards, mostly! Finn. Denmark

The standard 520mm bars will be too narrow and make the ride twitchy. You’d be better to fit Joseph Kuosac mid-rise bars, they’re 600mm wide and have a 100mm rise, SJS Cycles stock them. I run them on my 2012 Brompton H6R, trimmed to 560mm and they handle much better than the stock item.

@fender1000100 8 месяцев назад

That's a myth. I have a TERN VERGE X18. It's the only folding road bike ever made. An amazing bike. And the handle bars are narrow. And there's no twitch. But I can slip through traffic others would have to stop for. With 560mm or wider bars.

Those Shimano rotors only have "lightweight racing" 14mm deep brake tracks, and those TRP/Tektro calipers fit "heavy duty" 16mm deep brake pads. A common/fatal mistake I've often seen that eats very deep into 2mm of rotor spiders and causes rotor collapse. I use Magura MDR rotors with Spyre calipers.

If your going to do it properly, and want to be taken seriously, and don't want to be worried about it packing up every time you go out, there is only one multi speed hub gear to fit to any bike. Leave the Sturmey Archer on or fit a Rohloff.... If not, catch the bus instead.
