Pentagram Star Wheels

halfmile · Nov 18, 2019

Yesterday my friend brought the centering ring for the rear hub.'Perfect" :thumbsup:

All I had to do was index the mounting holes, drill through the ring into the original hub, tap the 5mm threads, and countersink the flat head screws. A couple of axle spacers and it`s ready for the next dilemma. :shrug:

Looks great Phil! I can’t wait to see the bike you’re going to build around those wheels!

Me Too.

The No Theme Bike started as a budget build to use up all my left over parts from previous builds but that went to "Hell in a Hand Basket" in about 20 min. I might try that again but this time I`ll leave out the word budget?? :doh:

Question, On the sprocket bolts I see you've done away with the folding(bending) lock tabs and gone with lock washers.
This has tempted me before to do as those folding tabs are so ugly. Loctite too ? Input here please :whistle:

If you're using the stock swingarm, using washers creates interference problems. Don't ask how I know..

What do you all think about this style lock washer instead of folding tabs ?

Another option is to use wave washers - they're not as thick as lock washers.

Folding tabs are about as fool proof as it gets. If done correctly they don't look bad.

I always use a 520 sprocket with a standard chain. That ads another 1/8" of clearance to the swing arm and shocks. The washers in the pics are just some AN washers. I`ll probably use the lock tabs as ugly as they are. :thumbsdown:

The axle in the pics is almost to the front of the slot. Lots of clearance. :thumbsup:

MaxPete · Nov 18, 2019

Yeah, I would use the lock tabs.

The consequences of a bolt or worse, a whole sprocket coming adrift are....<shudder>....not pretty. :yikes:

TwoManyXS1Bs · Nov 19, 2019

Yeah, and the tow truck is distracting...

That looks really sharp!
Standard chain? 520 chain? Or are you saying standard vs O-ring 520 chain?

Having a bolt back out of the sprocket will get your attention. It happened to me on the Blue Ridge Parkway. The folded tab wasn't done properly or failed, I don't remember as it happened in 2010. If I could buy metric bolts drilled for safety wire, I'd use them there. I know I can drill them, but I just don't want to.

halfmile · Nov 19, 2019

Yes. Non-0 ring chain. Marty is right about the drilled for safety wire bolts. If I could just find this low profile head bolt predrilled like this one in 10mmX125 pitch?? :thumbsup:

I installed the pentagram wheels on a mock up frame to check the fit of the caliper bracket (found 2 of them). Spacers and dust covers have turned into a small challenge. :umm:

The front is a bolt on piece of cake. :thumbsup:

Also dug out some old High Pipes I started and never finished. Imagine that. :shootme:

member28833 · Nov 21, 2019

Very Cool

Do you think those are lighter than stock XS mags ?

Mailman · Nov 21, 2019

I’m lovin it already! :thumbsup:

Looking so so good Halfmile! Love those wheels and the high pipes.

Mailman · Nov 25, 2019

So.....will this bike be sporting a new Radian swingarm? Hmmmm? :cool:

Anything is lighter than stock mags.
