Thanks for you input guys.
MartinF, mud wont be an issue, being a practical sort of guy read, anti-fashionista' I believe in guards tokeep thecrap off in.the first places, main sources, front chain ring from front wheel and back wheels as primeary chain-crap interfaces. It is tried and tested on another bike.
Mainenace regime simplified👍😀

Wow - that seems a lot On a Brompton - how does it handle with that load?

Been OK so far, I reckon over the years I have done at least 1000 km with the front bag/rucksack combination on a Brompton.

But I try and restrict weight on the rear as much as possible - all the heavy stuff goes in the front bag. Brompton rate this for 10 Kg, but IME it will cope OK with up to 20 Kg.

Rohloff Internal Hub Gears / Re: changing sprocket,uses for the old one?
« Last post by martinf on Today at 07:11:18 AM »
The plan is to make a dual rear sprocket.  half step between ratios. Replace the chain tensioner with a  short cage deraileur,
I believe this is possible by carefully selecting 2 close sprockets.
I tried this with double chain rings. It worked but changes were too slow.

My aim was to extend a limited gear range, not to get finer gear steps, but I came to the same conclusion with my "touring" Brompton.

First I fitted double chainrings and 5-speed hub. Later I fitted two sprockets (13 and 19) on the 5-speed hub and dispensed with the double chainrings. I needed to grind the raised tabs of the 19T sprocket, after that it fitted OK on the driver of the 5 speed hub with a standard Brompton 13T sprocket and slim spacer.

Two rear sprockets shift much quicker, and this setup is substantially lighter (weight counts, because I carry the folded Brompton). Downside is that the small 13T sprocket clogs sometimes in mud or snow, and the special pulleys on the Brompton rear derailleur are more hassle to clean than a front derailleur.

I've been running a pair of these on my own tandem and have been most pleased.

Best,

Dan.

Thanks! I figured!  ;)

When I first considered a Rohloff, I also pondered a half-step setup, but one using a single sprocket and dual chainrings (I prefer half-step gearing on my randonneur bikes). The steps and progression came out pretty nicely with a 2-tooth difference between the 'rings, but it would require both a front derailleur and a chain tensioner, where your scheme would eschew the front mech in favor of a rear derailleur instead of a tensioner.

In practice, I have found the single 'ring and cog on my Nomad to be "enough" for my needs primarily because my most-used gears are the same (in gear-inches) as my most-preferred half-step derailleur combos on my rando bikes. :)

Looking forward to seeing the result and all good wishes on sourcing the cogs you need.

Best,

Dan.

Hello all,
Thought someone here would be more likely interested in these tyres that are suited for Touring tandem bicycle. They were top of the line when I originally purchased but different projects have gotten in the way that they never seen action. I believe Schwalbe have discontinued this model some years ago even though it was popular with touring review sites and Tandem owners which reason why I went for them originally. The model is Schwalbe Dureme and part of their light weight and tough Evolution Line Double Defense Wire bead. Tyre size is for 26" wheel size and 2.0" width. There are three in total I have which I want to sell as a pack. I have a box to ship them all in anywhere in the UK. I have attached a few pictures just showing one tyre which still has the label attached. The other two are new and unused but sitting on two rims next to an unbuilt tandem frame in the garage.
Any questions feel free to get in touch. Asking 30 each so 90 for the lot and I will include shipment via DPD or UPS courier to the buyer within the price.

(The chain ring didn't have ramps etc to speed up the shifts.)
 Note, A eighth to quarter turn at the front will change the dual rear faster than a half turn Of the cranks, with a double-chainset set at the front.

I am currently on a triple chain set on the front, the inner ring is a chain catcher for poor shifts.
I dont really have 42 usable gears.28 will be enough!

Rohloff Internal Hub Gears / Re: Pedals turning when pushing
« Last post by ledburner on Today at 12:31:20 AM »
 How about putting a velcro strap on the side you walk on, crank to chain-stay or where-ever puts  the offending pedal ou of the way
Said strap , also can hold on the front brake or   front wheel to down tube to stop the bike falling over.......
Lot of uses......
