Re: Fixing a front dynamo to the bow of a low rider

Thank you for the helpful answers. I bought the mount suggested by Brucey, filed it down, undid the nut holding the caliper spring, put in the mount and then did up the nut. I added a spacer for a little more clearance to the headset, then used one of the longer spindle screws as suggested by Bmbibz...

Re: Fixing a front dynamo to the bow of a low rider

Thank you for the replies and my apologies - I did indeed mean the lamp not my dynohub. I have one of those lamps that meets the German regulations and, just from the pictures in the manual really, https://herrmans.eu/wp-content/upload-assets/PICC01673.pdf , I have been assuming it needs to go at fr...

Fixing a front dynamo to the bow of a low rider

I have had my dynamo mounted on the front brake, I could only do it with a bodge by putting on a longer pivot bolt as I needed spacers to stop it rubbing against the headset. Now I am thinking of putting it on the bow of my low rider - I think that keeps it at the right height but I haven't been abl...

at what weight do kids bikes start getting too heavy?

I'm looking at bikes with pedals for a 3-and-a-half year old. Islabikes are under 6kg. I don't think there is anything lighter. A Dawes Princess 12" wheel is just under 11kg. I've seen a second-hand Ridgeback that I think would be under 8kg once the stabilisers were removed. I know what I'm aft...

Re: General degreaser

I tried looking for some 'bio-degradeable' degreasers. The Gunk mentioned above has a 'Green' version and when I've soaked a filthy chain in that, it worked really well. Although, on the other hand, the more I learn about 'bio-degradeable' labels the less stringent they seem; eg the product could ta...

Re: Hub Dynamo for winter commute.

I sought advice on this forum 18 months or so ago and as a result bought a Shimano 3N72 hub dynamo along with a 'German lighting standards' LED front - Herrmans H-Black Pro, not one of the more expensive lights out there - and a cheap B&M Toplight Flat S Plus rear dynamo light. For my commute - ...

the recess inside a tiagra rear hub

I was regreasing my cup and cone hub today. Whilst removing one of the ball bearings I dropped it down the middle where the axle goes and it didn't fall out of the other end! When I looked there is a recess all around the way round the hub in the middle, I never even knew it was there. I decided to ...

Re: Please explain this frame

Hi, If the whole idea of this design is the make the rear end shorter........yes, and to make it stiffer? Why would you need the extra ultra small seat stays......... I had a Flying Gate made in 1995ish - my first ever custom frame and went to Tenbury Wells to talk it through with Trevor Jarvis. I ...

Re: Pedals suitable for barefoot shoes ( ultra-thin soles )

Would these be any good? - MKS Urban Platform Pedals - take clips and straps - perhaps the ridges would be uncomfortable though. I filed the two tallest ridges on the inside down on my mine. Had them for a few years with no problems and no maintenance required. https://www.sjscycles.co.uk/images/pro...

Re: Mercian Shop Closing

When I went to pick up my Rotrax a few years ago I was pleased to give business to a really pleasant person plus was given a giant piece of cake with my coffee. I know where I'm going if I ever need another one! Ridden the bike day in and day out ever since and it's a joy to be on - I mean literally...

square taper bottom bracket - cup not all the way in

I just fitted a Tange square taper bottom bracket and after tightening up there is abut 2mm of thread showing on the non-drive side cup. Is this OK or should it go all the way in? Threads were clean, I put some grease on them, the bottom bracket is new. There's no play in the axle and I did double-c...

Re: Guilford to London by Tow Path

It's fine as long as you are not in a rush and your bike can withstand a bit of vibration! Once out of the Guildford built-up area you'll be on towpath that is OK, with road-planings-type surface on some parts and various muddy and rooty bits elsewhere. A typical towpath experience really. An altern...

hub dynamo ratings

Just got a shimano 3n71 - and as other threads state, they really do tighten them up, I use shimano cup and cone hubs but this was something else. Anyway all backed off and grease added now. The hub is 3w 6v but I've realised I don't actually understand this, as the faster it goes the greater the ou...

Sturmey Archer HDS12 Dynamo Front Hub

Looking through some of the hub dynamo discussions, the SA does not seem to get much of a mention. I can see it has a solid axle and is heavy but does it have performance issues?

My thinking is a cheaper hub gives me money for better front and rear LEDs but if it has known issues I won't risk it.
