ORBO Vitamin 'C'lunk🍊

Good news everyone, cooler fits in nicely.

Impressive work on the brake cooler. So, does the aluminum absorb heat coming off the steel hub body then? I always thought aluminum didn't retain heat, that's why you can pick up the edges of an aluminum foil 'boat' with meat on a grill that is 350° and lift it off without burning your fingers.

I really like your custom twists and mods on this ORBO build! Your 'form and function' follow so closely, I'm not sure which I like better.

Finished machining the heat sink. I think the pics speak for themselves to answer that question from @BartRidesEternal View attachment 258406View attachment 258407View attachment 258408

You need to get to the Coaster Brake Challenge. I bet you could field many orders. I love this!

So, does the aluminum absorb heat coming off the steel hub body then?

The idea is like cooling fins on an old flathead, or a heatsink on top of a hot computer chip. More surface area to release heat to the atmosphere. The Moné site makes bold claims:

"Substantially prolongs the rebuild interval of your coaster hub. 100-150F decrease in temps over non-cooles hubs as measured by a heat gun at the end of a klunk race. Lower temps = less grease weep = more klunking and less repacking. I’m talking from 1 day to 1 year… A sisignificant increase. "

Yeah, the slacked out head tube looks really good, especially with the 650b front wheel.

I'm not sold on the frame bag, that bike has so many cool tubes and junctions and negative space between the frame tubes that it's a shame to obscure them.

I think you are definitely right on the frame bag. I took it off for the last few pics, really shows off the frame junctions. Thanks for the input.

Thank you so much,
As Matti said, the idea of the alum is to Help displace the heat.

Unfortunately a loooooong way for me to travel, would love to be there for an event though.

The Mone cooler was definitely an inspiration, I'm keen to destroy this hub with some epic down hill runs, but not in the first 5 Minutes

New chrome VMX bars arrived today. Little wider, and a little more back sweep. Perfect

That is a great looking klunk!

That is a great looking klunk!

Thanks dude

After a bit of use now, Shortened up the brake cable, adjusted the chain today. Really happy with how this build rides.
