[Upgrade Focus.2] Bromptom Chain Tensioner & Pulleys - Make your bike more beautiful with metal components!

BIKEfun Designing parts for Brompton become more than those for Birdy rapidly.

And the Chain Tensioner was the first BIKEfun Designing part for Brompton.

We have designed a series of components for Bromptom with our Partners.

With the growing amount of the components,

BIKEfun leads you to discover them by going through different parts of the bike.

And show you how Brompton can be improved!

Upgrade fever!~~~~~~~~~~~~~~~~~

You may never pay attention to the original chain tensioner and pulleys on your Brompton,

they are made of plastic and colored black. This is the consequence of cost down.

BIKEfun believes that you are not satisfied with those cost down plastic componentsbecause your partner is a classic English made imported folding bike instead of a cheap commuting bike.

Therefore, BIKEfun designed the metal Chain Tensioner:

Aluminum appeared with 19th Century's classic style through CNC processing.

Two versions are provided:

For Double-speed (2,4,6) and for Single-speed (1,3,5)

Each of them in four different colors:

Coppery / Silver / Black / Ti-Color

Price: 3,500 TWD

[Coppery]

Suggested on varnish, black bikes.

[Silver] Attention! Silver Chain Tensioner is made from gray (top) and silver (lower) two-color combination!

Suggested on white, pink bikes.

[Black]

Suggested on black, bright color (Yellow, Orange ) bikes.

[ Super Light Edition (Ti-Color) ]

Special designed for Ti Bromptons.

The color and texture almost the same as the titanium on the frame.

完全針對(鈦布) 鈦合金brompton車款所設計的特別版張力器，

陽極顏色與噴砂質感幾乎跟車架上的鈦合金顏色一致

Use aluminum to make better appearance and strenth than the original plastic tensioner.

SL version have lighter weight due to special CNC process.

The weight is 20% less than the standard BIKEfun tensioner - only 125g / set.

If you cares a lot about the weight of your Brompton,

we strongly recommend this tensioner for you.

for 2, 6 speed Bromptons

Super Light Edition(Ti-Color), Price：4,000 TWD

If you really like the metal style,

you may want it even better.

Perhaps you also want to change the plastic original pulleys.

BIKEfun provides aluminum pulleys for you to make it whole!

Like this:

Combine the chain tensioner and pulleys.

The pulleys have same options provided as for the chain tensioners :

Two versions:

For Double-speed (2,4,6). Price: 2,000 TWD / pair

For Single-speed (1,3,5). Price: 2,000 TWD / pair

Designs:

Raytheon

Three colors:

Titanium clolor / Black / Coppery (Silver Sold out)

Pulleys for double-speed Bromptons need to work well when shifting!

Therefore, BIKEfun designed oil channels inside the pulleys for grease to stay and lubricate when they roll.

In contrast with those pulleys without the oil channels, BIKEfun's pulleys works with less resistance and noise.

Check this out!

One tiny change of your Brompton made it looks better than before!

Beautiful!

During the progress of designing bike components, we met a lot of problems and difficulties, it is because of your support that we could make it success.
