Afterthought: Using some fibreglass mesh tape such as https://www.amazon.co.uk/APT-Tape-Re.../dp/B09HY1R2V7 instead of wire could be a neater solution. First apply a thin layer of epoxy (the slow setting type might be better) then wrap with tape and apply another layer of epoxy.

I see the Touring currently ships with a three speed Sunrace gear hub and a ten-cog 9-32T Sunrace cassette, and have a couple of questions:
1. What are the gear ratios on the gear hub, so I can computer the gear range?
2. Is that gear hub draggy or efficient? I intend to ride that bike in mountains so the less drag the better
3. Is that 9-32T cassette common? Once it's worn, can I easily replace it, with the same model or from eg. Shimano?
Thank you.

This Sunrace hub is not an IGH, its a hub for a cassette, the Riese & Müller Birdy Touring has a pure 10s derailleur transmission (while the Pacific Cycles Birdy Touring is a 3x8s with an IGH, quite confusing same model name for different components).
This Sunrace hub+cassette system is meant for small wheels bikes and is derived from the old Shimano Capreo group. Its proprietary, the hub only accept special Sunrace cassettes (with 10s or 11s) and these proprietary cassette can only be mounted on the special Sunrace hub (and maybe on a Shimano Capreo hub ?), mounting requires a special tool (similar to the Shimano cassette and centerlock disc tool but different).
Its very difficult to find these Sunrace special cassettes as spare parts. (same for the hub but there is usually no need to replace it).
The gear inch range provided by this 9-32t cassette with the Birdy Wheel size is excellent and fit the needs of most users.
For those like me who don't like that transmission, the other possibility is to use a SRAM XD or XDR compatible rear hub (the Birdy rear hub is a standard 135mm OLD hub with 5mm quick release) with a Ethirteen or 3T 11S 9-34t or 9-32t cassette same as mounted on the Helix Superlight.

deep maintenance
How do I maintain the rear joint axis? Any person with experience?
I just removed the axis because I noticed that it was run to the side, it was not symmetric,
The axis is a piece of solid metal, nothing in particular but the female axis in the main picture, has NEEDLE ROLLER BEARING and for a piece of nylon and has oxide, is there any replacement for that? icant send picture yet but im shooting for the future

This has some influence when mounting a front derailleur.

I have actually brought old 3 speed hubs back to life by feeding them WD40 and then when they start to work putting them back on oil. I think they get sludgy and WD40 breaks that up. The old hubs with ports seemed to be designed to leak.

A Sunrace 9 speed cassette 9-28 is available here:
https://www.somafabshop.com/shop/590...2340#attr=4801
Using Shimano cogs, it should be possible to modify it to 9-32.

Before I order one, for those of you how bought H&H's Front Carrier Block for Brompton Bag Lug Adapter, can you confirm that…
1. The inner distance between the two flanges is 71.12 mm
2. If need be, each flange can be rotated 180° to fit a non-Birdy folder?
And what's the height/thickness of each flange?
Thank you.

Hi all,
My Birdy folding hinge lever keep coming loose (pops up) as I ride. How do I adjust it? It is as simple as adjusting some bolt? I have a Birdy Gen 2. Thanks all.
Pictured is my Brompton T Line and by Birdy Gen 2.

Front panniers for first-generation Birdy mooncoque
I have a first-generation monocoque-frame Birdy (with a Rohloff hub) that doesn't have the screw-holes on the front dropout later provided to mount a low-rider rack. I wonder if anyone has successfully mounted front panniers on this model? If so how did you manage it?
Thanks
Thanks
