Re: Need waterproof flashing front light recommendation please

See this website for good advice on buying lights: https://swhs.home.xs4all.nl/fiets/tests/verlichting/index_en.html But he doesn't like flashing ones: On a rainy night I encountered someone with a strong flashing front lamp ca. autumn 2008, and I blurted out 'gek' (idiot, or better translated proba...

Re: Nexus 8 still slipping

Brucey - I'm not sure if I made it clear in my earlier post that I actually removed the cap nuts and non-turn washers, removed the wheel from the bike, removed the cassette joint, dust cap, snap ring and sprocket, refitted the cassette joint only and actuated it by hand. When it stuck I removed the ...

Re: Nexus 8 still slipping

Brucey - I see your point about the shift ramp being a bit steep and needing to be worn down by use. But I'm not impressed with Shimano's quality control in shipping new hubs with a built-in fault. It reminds me of British Leyland. Is the sliding clutch under constant pressure from the spring, or do...

Re: Nexus 8 still slipping

There may be a co-operative cycle workshop near you, they may be able to help. Brucey - there isn't anywhere like that in the North East. Hub gears are rare because it is so hilly. However, I think I have diagnosed the problem. I followed your advice and removed everything from the drive side of th...

Re: Nexus 8 still slipping

Well, I replaced the cable and shifter for the fourth time, and the axle nuts and the non-turn washers. But I still have a problem. I have not been out on the road since I got my new frame and hub for fear of damaging something. But in the workshop when I turn the shifter from 1-4 to check the align...

Re: How important is chainline?

Brucey- bear with me on this please. Having read Sheldon's instructions again, I now think that my sprocket is at position E on the chart, i.e. an outward dished sprocket. If that is correct my rear chainline is 49.5. But I intend using a 1.5mm dished SA sprocket, so if I flip it I can reduce the ch...

Re: How important is chainline?

I can see the arithmetic, but I don't understand how reducing the dish can move the chain further away from the frame. At present my 3mm dished Shimano sprocket is at position C on the diagram. If I fit a 1.5mm dished SA sprocket won't the chain move halfway towards position D? Logic was never my st...

Re: How important is chainline?

Brucey - I obviously misunderstood those instructions, but thanks for clarifying that. I've got a brand new frame, so I hope the alignment is not out. But Sheldon Brown states that the SA sprockets are only offset by 1.5mm, so the rear chainline will be 42mm. Is that still OK?

Re: How important is chainline?

Brucey - The SA deep dish sprocket is only available with 17 teeth for some reason. I think you're right about clearance, so I've ordered an SA dished 20t 1/8" sprocket to replace my Shimano one, and a KMC B1 1/8" chain. I understand the sprocket dishing on Shimano and SA is the same. As f...

Re: How important is chainline?

One of the other methods of adjusting chainline would be a better idea.


Brucey - which one would you suggest?

Re: How important is chainline?

My Nexus 8 IGH chainline is slightly off even after flipping the rear sprocket, i.e. the front is further out than the rear. As per Brucey's advice I'm going to install a 1/8" chain and Sturmey Archer dished rear sprocket. Will I still need a chain tensioner?

Re: Nexus 8 still slipping

zenitb - My Travel Pro is the 2016 model, which came with a chain. Unfortunately I had a lot of bother with it and the shop replaced it with the same frame as yours. I am curious about the tool that you have ordered as I had one from Park Tools which had two pins, like this one: http://www.wigglesta...

Re: Nexus 8 still slipping

Well I can't find out how to move the bottom bracket to adjust the chain. But as there is just a hole from one side to the other I reckon I could slacken the clamp then pass a thin bar such as an Allen key through it then push/pull it backward and forwards?

Re: Nexus 8 still slipping

Brucey - the Cube manual is a generic one printed in 2015 and does not mention BB adjustment. The BB is called a Thun Zumba but their website does not appear to have any manuals or instructions.

Re: Nexus 8 still slipping

Brucey - thanks for that. Would it be wise to replace the cable and housing, which only costs £12 with a new shifter from SJS? Although the NTWs are made of steel, should I replace them anyway as they may have been worn by the movement of the axle? Although the new frame can be used with a belt I am...
