A brake bleed on the inbred ready for a ride after work tomorrow
Moderators: Bearbonesnorm, Taylor, Chew
Really feel sorry for you... Few weeks ago my sons mate pringled his wheel. Claimed he hit it but I think it was so cheap and cheerful (trying hard to sub the word 'nasty'). He's a nice lad so I told him I'd have a look at it. Untensioned all the spokes and still pringled. Then I sat it under some weights for 48 hours... Still pringled.Bearbonesnorm wrote: ↑Mon Nov 09, 2020 12:32 pm Dee's friend wants a bike, she has very little idea and seems to view bikes as a 4 year old would. With your help, I managed to find her a few budget offerings that would do the job nicely. However, she seems to be very tight and happened to send a pic of something she'd seen on ebay. It was a horrible 'full suspension' Muddy Fox badged bicycle shaped object.
I laughed and then like a nob, I mentioned that there was something identical sat right at the back of the cellar. Ooh that peaked her interest, so I told her while she could happily have it, in my opinion, she really didn't want it ... to cut a long story short, guess who now has the job of rolling this particular turd in glitter?
There's no front brake, BB is completely shot. No bearings in the headset, mech' hanger's bent, rear wheel bearings have 1/4" of play, etc, etc. I bet you're all envious![]()
Even the camera refused to take an in focus picture of it.

Yes, it really is that sh1te ColinErr, is Ruddy Dax ripping off Muddy Fox?

Oh if only Phil but sadly I think she's coming for it before thenMaybe you should ride it on the winter event just to make sure its sorted
This makes hopeful. I have a SP hub that there's no output from, so I want to strip and check for broken wires. My last attempt at dismantling a dynamo hub involved a hacksaw and it definitely wasn't going back together.htrider wrote: ↑Mon Nov 16, 2020 1:23 pm SP Dyno hub refurb continued.....
Just to follow up on my post on the previous page, I finally got new bearings, hammered them in and re-assembled the hub which appears to work![]()
The only thing to note is that the magnet is driven from a central ring which gets pinched between the two halves of the hub shell. I stuck all this together with loctite bearing fit and left it overnight whilst clamped together in the press. Overall this is easy so dunno why they insist you have to return the hub to Taiwan to get done.....
It could be one of the output wires as they are pinched under the outer spacers and could easily get chaffed - easily checked by unscrewing the end cap, pulling off the plastic housing that the wires sit in and then pulling off the inner spacer. If its a problem in the windings I think this may be beyond home repair as it wasn't obvious how you got the armature apart and I think this is the bit that has to be pressed together precisely right.... No harm in having a look thoughslarge wrote: ↑Mon Nov 16, 2020 1:38 pmThis makes hopeful. I have a SP hub that there's no output from, so I want to strip and check for broken wires.

Duncan, how have you attached the bottle to that top tube mount. Looks like its being sucked on as opposed to a cage...
Thanks for this... Fidlock (pending weight issues for my lightweight commuter) here I come..pistonbroke wrote: ↑Tue Nov 17, 2020 11:13 pm Shaf, it's another of Fidlock's products, a 600ml bottle which attaches to a magnetic mount. You twist it to detatch and just place the bottle by the magnets to re-attach, works perfectly. I didn't want a cage in a position where I was likely to disembowel myself if I had to get off in a hurry. I had a different design but same magnetic idea bottle from Vincero Designs but the bottle started leaking around the magnet and they don't make them anymore.
Hey hey - found a broken wire as it passes under the bearing. Just now need to pull that hub shell off and should be able to fix it. Then rebuild the wheel (which I was going to have to do anyway with a new dynamo hub). You're right though - the bearing replacement shouldn't have to be a return to Taiwan job, but it is a right fiddle and most shops etc wouldn't have the time. Plus it's easy to break bits. It is quite feasible to refurb borked hubs when you've done it a couple of times though (as long as it's only the bearings that are shot).htrider wrote: ↑Mon Nov 16, 2020 4:57 pmIt could be one of the output wires as they are pinched under the outer spacers and could easily get chaffed - easily checked by unscrewing the end cap, pulling off the plastic housing that the wires sit in and then pulling off the inner spacer.

Good work, always good to fix things rather than have to buy a new oneslarge wrote: ↑Wed Nov 18, 2020 3:35 pm
