Hi All.

Got a question for anybody out there who's spoked more wheels on a Bantam than had hot breakfasts.

I've just got my wheels back from dealer who rebuilt both front and rear wheels for me. (He didn't need the photos I'd taken before dismantling them as he'd done Bantam wheels before). 

Front wheel looks really great now and comparing it with the photos everything looks perfect.

Rear wheel - see pics attached here.Wheel-before-renovation.jpgWheel-After-renovation.jpg

In first pic (before dismantling rear wheel) the outside spoke goes in clockwise direction (/)

In the new renovated rear wheel the outside spoke goes in anti clockwise direction (\)

Everything else is great. The spoke pattern is the same as was except for that detail. 

Question is this - Does it make any difference???? I can't think why it should - but then there's that niggling feeling!!

Any info from experienced spoke person would be greatfull. bow

I've built a few bicycle wheels and it would make no difference, its the interleaving and tension which creates the strength. One difference with motorcycle rims is the angled dimple on the rim. So I would check whether the nipple is seating in its dimple on the rim correctly.

My mate Wayne helped me rebuild a wheel or two last year, I've done lots of pushbike ones in my youth and have done quite a few bantam ones too, problem I had was on two full width hubs for a d14B put spokes both ways and lots of threads still showing despite spokes being so tight as to almost strip the few threads that were still holding it all together, it all turned out after much head scratching and three rebuilds later on just the front wheel that all the spokes were 3/8ths of an inch too short!

I'm still waiting for my supplier in the good blokes guide to get back to me, I sent him an old spoke too, but nothing, months later, I just copy any old wheels' spoke pattern that is laying around generally.dd.

Did as Robbied196 suggested and checked if the nipples were seated Ok.

They do look OK. 

But on the long spoke side (ie the non brake side) the spokes are about 4 or 5mm short of the top of the nipple. None of the spokes on the long side even reach as far as the screwdriver slot. I assume that all the spokes should be almost all the way through the nipple.

All Spokes on brake side are OK as they reach the end of the nipple.

I've measured the spokes on both sides and they seem to be the right length according to the manual (D14/4 manual) - 201mm and 165mm. I assume that B175 is the same.

The offset is OK at 36mm approx from edge of brake drum. That's what I measured it to be.

So, has the reversed clockwise/anti clockwise direction of the spokes caused one side to be too short for the nipples?

Any spokes person out there??????? bow

Most if not all books and articles on respoking wheels generally mention using caution when cutting the spoke ends off that protrude through the nipple, taking care to not leave sharp ends that might puncture the tube?

Perhaps like me, your builder received spokes that were too short, but only one side? Maybe rather than concern you he just got on with it to get job finished and out of the shop?

Only guessing here, please don't hit the roof and lose it! Not many more explanations left, except maybe starting with wrong spoke pattern and cutting spokes too short and then realising mistake, rebuilding, hoping for the best and hoping you'd not notice?

Sorry, I really must not keep making things worse.

As long as the spoke is about 3'4ers in the nipple it should be ok, but I didn't rebuild that wheel, nor will be riding that bike, you need to contact your builder and get an explanation, an old experienced hand would not use materials unfit for the job.

There are even cheap copies of bantam spokes around now, like mine, someone just roughly converted metric to inches after a night out and must have had a hangover!

Know exactly where you are coming from.

Thing is, all spokes used are the ones I gave him - taken off the wheels by me and repainted etc!!!!

I can see the end of the spokes inside the nipple and unless they've developed premature rusting (only tiny speckles) - he doesn't appear to have cut them.

Old established bike shop with good reputation!!!! Will phone him tomorrow for explanation.

And by the way I do have a few sharp ends that need filing. Surprise, Surprise.

Also had a look at my Wipac generator (B175) it's awful greasy and dirty looking - any suggestions on how to clean and tidy up without causing damage. Is it even possible to get a replacement if needed??????????

I need a glass of something cheers

Hello, as per the generator, sounds like an oil seal may have gone on the engine a long time ago perhaps, or even the shield that protects the generator from the chain and sprocket is bust?

Anyway, impossible to tape up, can't spray on anything because of the oil, not unless you could degrease it and that could short some coils out?

Best just have a Guiness I reckon and look out for another set of coils on feebay? David.

Is it possible he mixed up the front and rear spokes as they're different lengths?

As for the generator, which bits are dirty? As long as the business ends are clean, I wouldn't worry, but that's just me 🙂
