21 inch Woody's build Tubeless Front....

Just mounted the new Woody's build 21 inch tubeless front. Zach build it up with a Rad hub, and sun Rim, as the Sun rim is the only one with the safety bead to hold the tire in place. Decided on the TKC-80 as a solid combo.





For you that are interested...... The new superlace/RAD/Sun/TKC-80 combo weighed in at 18 pounds, and the stock wheel/tube/Metzeler Karoo2 combo was one pound heavier, at 19 pounds. It feels the same riding it on the asphalt @32 psi, but as I get some dirt time in, I will report on the wheel, as I already have the 18 inch rear tubeless in place.......

That's a nice setup. What's the rim width?

Thanks.....
First they seal each nipple on the top with soft gue like silicone..... then the whole center part of the rim gets a bead of harder silicone. It then dries for three days, and the rim then gets taped with structural tape. Sort of the same tape we use converting mountain bikes to tubeless, known as Stan's yellow tape. Price is just around a grand. The 18 rear was a bit more. Full tubeless....

Only drawback, if any....The sun rim with the safety bead only comes in 2.25 inch, like stock. I would have liked perhaps 2..... but on the other hand, the narrower will be good for offroading, as it minimizes pinch flats, but on the contrary on road, you can peel the tire off easier with a narrower rim. I have done plenty of techno stuff, and think the 2.25 is a great all around solution, in and out of the dirt.

Assuming you air down off pavement, how far down do you feel safe going with that new setup?

I have always been airing on the side of caution. 26 front, and 28 rear. With that same pressure, I have gotten to within inches of dragging the boxes on curves, and had no issues. I have blasted through rocky up and overs..... step downs of 10-12 inches.... Dirt climbs of 45 deg's, and always felt that 26/28 had plenty of cushion to as not to pinch flat. I ride hard, and don't always pick the easy lines, but tend to go through, and over more than the average rider, and with such, want assurance that I will not pinch flat. The 26/28 combo was huge in traction improvement, and I am certain, that you can go 22/24, but you now risk pinch flatting with my riding style. So for me 26/28 is the sweet spot.

(ps) Zach at Woody's said you can rip it down to 26, as much as you want. Below that you need to be careful hammering a curve on asphalt at 80 mph.....

I sealed my front rim myself (Excel) and I find anything below 22-23 psi starts to transfer impact to the rim on square edged hits with a TKC. You'd probably do damage with stock suspension. Better dirt tires seem to handle lower pressure more gracefully but the potential rim damage makes me nervous so I try to stick with about 25psi.

Cool. Thanks. I don't go below 26 (on purpose ), so those numbers sound good to me.

What is the advantage of the replacement hub over stock?

Lighter, and stronger, and I can sell the stock wheel, to someone needing a spare......

Been debating tubeless myself... Keep us up on how you like it. I'm sure there will be no complaints about not having to carry tubes. Ha

That is a sweet setup. I think I will order one too. Thanks for letting us know it's available. I had them seal my factory rear about a year ago and it works great.

Yeah, I now have more than 30K miles on my Woody's rear. It still holds air better than my tubed front.
