Glad to see the two speed crap going in the richly deserved bin. Luckily I'm stuck in the harder sprocket for my flat-ish roads.

Hello, could you tell me what size of circlip for the X3 I need for a BWR 6v brompton hub? Thank you

[@781BromptonPremiumParts]

.8 is the one we use

[@javiervaldivieso83]

@@781BromptonPremiumParts size 2.8 mm?

[@sese75kenneth12]

Hi may I check with you why my Brompton B75 rear wheel is slightly more to the right side of the triangle tube ? Is this normal built for Brompton ??

[@781BromptonPremiumParts]

Hi Kenneth, its really hard to say something without seeing your B75, but all Brompton goes to a high-quality control, have you checked with your dealer?

[@sese75kenneth12]

Honestly speaking the Brompton UK replied me as this is a normal built of a Brompton and there is no concern for it but i just can’t accept this it is so near.. any email that I can have so that I can sent you some photos ..

[@781BromptonPremiumParts]

@@sese75kenneth12 yeah try to connect with us on Facebook, we’ll have a look.

[@kelvinng3556]

what are the Cog sizes you got there? Are they good for speed and climb?

[@781BromptonPremiumParts]

Hey Kelvin, we use Minimods x3 unibody on this build an 11-14-17t that is very good in speed and small hills but if you want a good speed with climb then go for a Minimods x2 an 11-16 combination that can partner with 18 or 19 or even 21t as the third cog.

Do you recommend changing the chain pusher as part of this upgrade to? I find I can’t Index 100% with stock part.

[@781BromptonPremiumParts]

Hi Kieran, H&H chain pusher is needed and essential with this upgrade, it is longer and it comes with rollers as well that makes it better than the stock ones.

[@wz3815]

could you please give me a list for the 2 to 3 speed upgrading, thanks in advance.😊

[@781BromptonPremiumParts]

You will be needing the following:
H&H Chain Pusher
DT Swiss 3-speed shifter
Minimods X3 Cogs
Minimods Ti Barrell
MInimods Spring
Shifter Adjuster (Optional)
Hope that will help you start your project!

does it break the color of the rims with the v brake ?

[@781BromptonPremiumParts]

Its normal to have brake marks on the rims Rafi but Joseph Kuosac has a guarantee of 200,000 kms lifespan

Good but could've been a whole lot better if the cameraman/editor didn't have ADHD.
