Have you any recommendation for this?

I have seen suggestions of a derailleur friction lever or using two of the three positions of a Sturmey Archer trigger. What do you think?



I have been using two of the three speed trigger controls. I make sure the lefthand one is adjusted tighter than the set up position recommended by SA, the flat on the toggle chain is slightly proud of the end of the axle. If you attach a toggle chain to the axle and pull whilst watching the sun pinions move you will see that once the gear has engaged there is a smaller amount of further movement possible as the spring compresses. It appears that the gears are less likely to slip if the cable adjustment pulls things tightly. I suspect that in use there is a small amount of rocking movement between the sun pinion and the dog ring and that the pinion slowly 'walks' out of engagement, slips a tooth or two and then re-engages due to the action of the spring.

Steve,
wot's been busy working 16 hours a day all this week (so much for retirement! I know. It's my own fault for going back :oops: )


Well I'm glad to see you are leading the way now that the government say we've all got to work until we are 70+ Specially you public sector types with your "sick note culture" and "millionaire pensions". Hey just a minute aren't the government public sector?

Mike wot can't wait until his wife retires from nursing with her millionaire's pension :-)

Thanks Steve. I was tending towards the two trigger approach so am reassured by your advice.

It's finally properly finished, all tweaks, changes and adjustments completed :D just in time for impending unemployment :( Who was it that said the unemployed should "get on their bike"? :|

That's lovely Graham. I do like that big lamp! :D

I have some good news too! I finally got my Pashley sorted. SJSC built me a wheel around the XL-RD3 hub I bought earlier so today I've fitted it which took a while, but that's partly because I had a few other jobs to do as well, like change the grips, fit a new mirror, change winter tyres for M+ etc,.

I found the main challenge was tightening the cone in such a way as to get the torque arm to line up with the bracket on the chain stay. Now I've worked it out I'll find it easier if I ever have to do it again. I also put the sprocket on the wrong way around which left me with a kinky chain line so I had to take the back wheel off again to turn it around. :roll:

The 3-speed trigger that came with the hub is rather plasticy looking, so I might replace that sometime, but it seems to function alright so I might just wait until it fails.

The XL-RD3 hub itself feels super-smooth. Gear changes feel positive too. So far I'm really pleased with the result; I haven't been out for a long ride yet - will go for a spin shortly.

Many thanks for your help and moral support everyone - I can't tell you how good it feels to get my favourite bike back on the road, and it seems to ride so much better now with the newer hub. 8)

Lovely bike Graham. Is that a tent in the background? Are you rehearsing camping for TCT2?

Gorgeous bike Graham.

I'm in the process of building up a late 40's Raleigh Clubman myself, but I'm going for more of a 'scapheap challenge' look since I don't have the time or money to do anything more :( The frame has been power coated a rather nasty shade of green and it'll be running steel 26 x 1 1/4 wheels (with a 4 speed FM hub though :) ), but I'm looking forward to riding it all the same.

Very nice. I like the position of the bottle cage; where did you get the bracket from?

That looks like a dynamo front light - how do you power it?

The bracket came with the bottle cage, got it on fleaby from Rotec Cycles near Reading, three quid I seem to remember.

Light isn't powered, I was going to use a dynohub, then I remembered how much I hate them :lol: and I can't get the GH6 dynamo-side bearing cone to stay adjusted :| I'll probably gut the lamp and put an LED light and batteries in it at some stage.

Hope so, it would certainly be the last bike I'd sell if I had to. It would probably win over the car if push came to shove. It's a joy to ride, a proper joy. I'll never have another Raleigh though, I'd be too disappointed with it after this thing 8)

Graham, wot ackcherly likes a Raleigh :shock:
