【BROMPTON x Custom】Customisation of 5 speed exterior x 3 speed interior for a total of 15 speeds

【BROMPTON x Custom】Today we would like to show you

External 5 speeds X Internal 3 speeds.

Introducing the completion of 15 speed customization

Folded state.

Of course, the Brompton's original folding system is not affected.

The same as before, even with 15 speeds.

Brompton style.

Photo shown the rear wheel side customisation main parts.

This time, we used X series Advanced Gearing System parts from MiniMODs.

Brompton exterior 5-speed custom cog set (#X5unibodyCogSet)


This is a 9 spline type.

It can be assembled to Brompton internal gear hubs of 9-spline type (e.g. BWR hub).

The kit is designed to fit the 9-spline Brompton interior hub.

As assembly requires adjustment to suit the individual differences of each part, the kit is currently not available by mail order from our shop.

We are currently not accepting mail order kits.

Only custom orders can be placed in-store.

 Please note that we cannot accept custom orders by mail order only.

The levers chosen this time are

similar to that of shimano flat handlebars, which is well received by owners who are familiar with road bikes.

On the other hand, due to the shape of the assembly part

When combined with stock Brompton brake levers, this type of shifter is not as good as it should be.

For this reason, the brake levers have also been replaced.

In addition, the wiring of the cables has been renewed and reviewed.

We were able to achieve both a clean look and operation.

In addition to the Brompton's original interior 3-speed

The exterior 5-speed gearbox has been added to the Brompton's original 3-speed interior.

The gear choices when riding have been expanded considerably.

The front chainring has been changed to 39T according to the owner's wishes.

This gives the bike an amazing ability to cope with hill climbing.

The owner of this bike has had a lot of work done.

Various customisation ideas have been discussed with us since the delivery of the new bike.

We would like to take this opportunity to thank you again.

We look forward to working with you in the future.

We would be happy to offer you a customised gear system to suit your Brompton and your wishes.

When you are considering a customisation, please feel free to contact us.

We are looking forward to your visit with your Brompton.
