Re: Non bike tech question!

My Samsung has a "request desktop site" / "request mobile site" toggle in the three dot menu top right hand corner of my browser. It has a dramatic effect on some sites but not this forum. YMMV

Re: Suspension power losses/savings

However what is less obvious is that just pedalling hard tends to excite a type a) resonance and this tends to absorb energy all the time, even when the suspension has little or no work to do. Hence my earlier comments about needing to pedal in a specific fashion. I have yet to meet a rider that co...

Compare a ride on a narrow tyre-ed Moulton to a Raleigh 20 (shopper or chopper) you'll know what riding through treacle is like. :lol:

Re: Quill Seat Posts

Quill seatposts are the wrong solution to the problem as you would be putting forces on the seattube in a direction for which the seattube is not designed. a bold statement indeed with little justification or clear explanation :shock: Not obvious to me how the forces from a seatpost onto a seattube...

Quill Seat Posts

Came across this https://www.youtube.com/watch?v=4TkjA41tJ78 today.

Made me wonder why the scheme was not more common given all the aggro that you can get with binder bolts and clamps.

Re: Sturmey Archer indicator rod (control toggle) lengths

Thanks for this. Very useful reference.
I've printed it to pdf and put it in my S-A folder. I always find searching the Cycling UK forum very hit-and-miss :oops:

Re: It's far too dangerous to cycle on the road

Glad I don't commute atm! But it's nothing a set of Ice Spikers couldn't sort out. :lol: Had my first ride on on every combination of water, snow and ice this Wednesday using fixed wheel and studded tyres. It was great. Never felt any loss of traction at all, even on the icy sections. I had used th...

Re: Left ergo to operate SA AW hub?

BTW you can buy different length indicator rods to match the axle, and thus reclaim the indicator function. If the axle is a one-off then you could make the indicator to match. Another method that works OK if the rod is the wrong length is to use a paint mark and/or scribe mark on the toggle chain ...

Sorry, I don't remember. I must have got it second hand in the 80s. I thought the original S-A 3 speed hubs all had threaded drivers which were replaced on later models with the three spline driver. I can't find my Hadland S-A book to confirm :( .

Re: Left ergo to operate SA AW hub?

Thanks for the kind comments. It is a 60s AW hub. I got the threaded driver separately. I used to be a more active Moulton Club member and cycle jumble attendee. Yes it has the longer axle; as mentioned back up this thread, that's why I can't rely on the indicator rod to tell when I am in the optimu...

Re: Left ergo to operate SA AW hub?

Still haven't been on maiden voyage. Apologies. Too much other stuff to do. However I thought I might post some pics for anyone interested in hybrid gearing and/or 60s Moultons. https://mxhnfa.bl.files.1drv.com/y4mjtdUCm3X4isbwCvQhwb13GUrHmOgnKiYWlTnQRK30AGBRmrDjhDn_myrpQZ2DROeAMtuUQ-89Ve-DL-HE1ldOq...

Re: Left ergo to operate SA AW hub?

the required cable pull varies a little bit depending on the age of the hub. But if you have gear 3 = slack cable gear 2 = indicator rod correctly positioned gear 1 = no slack then you should be fine Gears H/3 and L/1 will be fine: it's N/2/direct drive that concerns me. I can't use the indicator r...

Re: Chainline again sorry

Difficult to say from a distance. Could you try to get some guidance from Condor? Can you not extrapolate from your existing setup? Try it with your existing BB. It may be close enough. If not, go incrementally from there with a longer or shorter Shimano sealed unit. They are available in a fair ran...

Re: Left ergo to operate SA AW hub?

OK, so, I've done it. I measured the cable pull per click on the existing S-A 3 speed trigger by taping a ruler to the frame and putting a masking tape pointer on the bare cable. Setting zero at the slack cable/high gear point (H), I got 8.5mm to the direct drive position (N) and 12.8mm to the low g...
