Hi there. Never thought I can setup my first UA-cam video. Upgrading Brompton has been my recent pastime during pandemic. Upgrading Brompton is not necessary an expensive thing. The parts in the videos were mostly unused spare parts I bought from the eBay.
Some references on Chainring / Chain length ratios :
Chain length: 96 links
44T front chain ring with single 12/13/14 tooth rear sprocket
Chain length: 98 links
50T front chain ring with single 12/13/14 tooth rear sprocket (3 speed Brompton)
44T front chain ring with single 16T rear sprocket or double rear sprocket
Chain length: 100 links
50T front chain ring with double rear sprocket (12/16 or 13/16)
54T front chain ring with single rear sprocket (12/13/14T)
Chain length: 102 links
54T front chain ring with double rear sprocket (12/16 or 13/16)
Standard 2 speed uses a 54T front and 12/16 combination on the rear
Thanks, I am getting mixed information about whether 98 link chain can be used for 50 teeth chainring and 14t single rear sprocket for 3 speed Brompton. Can I ask where did you find the information?
Please check out "Brilliantbikes" UA-cam channel. I benefited from it a lot.
I was wondering if you could add a third sprocket in order to make it 9 speed!!?
Yes it can. But I think 6 speed is enough for me unless I decide to remove the internal 3 speed hub.
I just bought my black edition 2022. I am thinking of swapping the seat. How do you like your B17 Brooks saddle? Is it as comfortable as they say?
I think it is quite personal feeling but my opinion is that it is very comfortable but also quite heavy. I therefore also keep my original Brompton saddle just in case I need to travel around.
By using a proper tool wrench and - top for the purpose, you don't need the tube.
Thank you for your advice.
@@kkllbaba And if using the original Brompton toolset, for the frame, you may use the tube it is inside, as a handle.
Nice !
Many thanks for your support.
Do we need to tune gear hub after changing the chainring?
No need. It works fine for me.
well done on your first upload. However, UA-cam will probably ban this video quite soon. Under the T&C's it is clearly stated that Jazz or any other improvised scratching on chalkboard noises is prohibited. It breaches the Human Rights Act 2018 and is regarded by the UN as a weapon of mass boredom. Accepted sounds are light whistling, humming and la de da's under 10db.
this audio is provided by youtube though-
Haha. Funniest comment I have read in some time 👍
Very funny 😆
