What have you done to your bike today?

Paige, no!

Yes, it fits the lathe (barely), and yes, the motor is strong enough to cut (barely). What can I say, couldn't pass up a deal for something bigger than I needed.

Follow up, first cut:

PXL_20250607_143639153.jpg


Used the parting blade's normal action to leave a "skirt" around the ID of the part, that runs up the preload collar/perch, so there is no metal/metal contact with the spring.

There are a few manufacturers of shocks that use plastic thrust washers (else something functionally the same) on their damper bodies to keep the spring from winding around/clicking against the preload collar/perch. I searched for a couple of hours trying to find someone who (surely) must make these for other shocks, before finding...none; while I have nothing in particular against a shock making noise--as long as it's normal--it makes chasing down other issues difficult, to say the least. Finally having a day "off", I set to finishing making the bearings for the shock:

No more creaking/clicking as the spring frets around, and it will perform as a thrust washer, too. It looks "too small", but the spring perch on the other end is the exact diameter of the bearing.

Now to find something to do with another 11 inches of UHMW polyethylene...

98% of the mystery creaks and clicks on my bike end up being the Kitsuma spring regardless of where I think they're emanating from. I've been putting a bit of grease on the end of the spring and it's been prolonging the inevitable noises.

Very cool , tf tuned sells a plastic thrust bearing but not sure it has a shoulder.

TF Tuned Spring Bearing

TF Tuned rear shock spring bearing

I recently got a bag of stainless steel washers from mc master car that I'm using as a thrust bearing on the end of the shock so the spring has a full 360° surface to sit on . Seems to help with occasionally backing off the pre load collar. I over spring my coils and run minimal pre load .

Europe tends to have people that do stuff like that [J-tek, Newman, et al], but shipping becomes prohibitive. The big-ol-chunk of UHMWP cost me $40 to the door.

Of course, if I didn't already have the lathe...

I'll let you know. The garage test was promising, and there's ~ 4-5 more left on the piece in the chuck.
 
Melted wheel rebuild. Left these in my trunk for a few months and the front rim melted. Was riding it and didn’t even realize it until someone pointed it out. Dodged a bullet.

Also went down to 28s because the 30s barely fit in my S3 on these wheels. The 28s measure 30mm and the 30s measure 32mm.

Successful test. The only 'creaky' sounds I got were from my saddle [the ti rails need to go. Anyone with experience using a carbon-railed Silverado before I plunk down the cash?].

If you want to test a pair, I'll send you them for postage. Not bold enough to ask for actual money yet.

New SRAM or new asparo? I think new aspero is coming soon

Both. Sram dropped new Force and Rival yesterday. Basically made them have the same hood shape and massive braking power/pad clearance as Red24. Current Force to Red24 is like running Levels vs Codes. And they get the aux buttons to control the computer or shift depending on how you program them. I’m waiting for a 50c compatible Aspero5, which is probably 2 years away? I feel like they just launched the one with the SWAT last year.
