Tubeless Mission Getting Out of Control - New Wheels Incoming, PowerTap G3 For Sale...

The new Schwalbe Rocket Rons refuse to go onto their rim. Below is a my latest and hopefully last attempt, here soaked in soapy suds with big bubbles, after adding another layer of Stan's tape AND one of the original rim strips below the Stan rim strip.

 soapy tubeless fail mess

So to work I go and I make some decisions during my latte walk - selling the G3 Powertap Wheel to fund a new set of real tubeless wheels.

Stan's again, rat bastard it better work this time - Arch Ex 32 holes with XT hubs incoming Friday from Ebay for $380. Tim suggested Flow would be tougher, Stan's claims these are good for riders to 230lbs. We will find out.

Looks like Barb might get those lightweight wheels for her 29er afterall.

Going Tubeless - ARRGGG

During the Bogg's pre-ride I decided I needed a new rear tire anyway, might as well go tubeless in the 29er to gain whatever benefit I could.

First I figured out the Rocket Ron's were some of the lightest, fastest and most expensive tires around. Ordered 2 online from "TireManiacs". 2 of the fast guys on the ride, Tim and Ryan, ride the WTB Bronson TCS, so I thought I'd pick one up at REI using my "dividend" and 20% off coupon. Coupon expired, and I found a Cygnolite flasher I just had to have too.

Went to Mikes Bikes the next night after the Internet told me they had complete Stan's Notubes 29er XC kits for my DTSwiss XR 39, a Scott-specific product like a DT Swiss  X470 rim (not tubeless). They did not have the kit, but they did however sell me rim tape, Stans fluid, and 44mm valve stems for a Stans ZTR tubeless rim, which I DO NOT have.

Result was a big mess and broken heart. After frantic pumping for an hour,  I went inside to check the Internet, watched some videos and realized I had the wrong stuff for my RIM! So I ordered 2 XC rim strips for another $50.

The WISEST thing I did was to put a tube inside the new BRONSON and mount it up for a few days to get its bead set and newness off. I rode the bike to work this am, trying to see if I could notice a difference - it just felt heavier. I found the new Rocket Rons had been delivered in the am.

On the ride home from work, I hit something to loose some air out of the rear tire, and then landed very badly on a ledge during a bunny-hop that pinched the tube. Loosing air fast, I did make it home before it was unrideable.

New rim strips were waiting for me. I removed the front Bronson, carefully cleaned with rubbing alcohol and put on the rim strip. It was heavish, and seemed to be providing a step to make the tire fit better. On went the bronson, I put a little soapy water to help it seal, started pumping and suddenly
it was working/sealing, without sealant even! I opened the bead and put in 60-80 ml of Stans fluid, carefully got the bead back on and pumped it up again without spilling anything.  I shook and spun the wheel, added more pressure. It worked!

I pondered not using the new Rocket Ron's at all, just move the front tire to the rear, but I noticed some damage and thinnish sidewall - the new tire's definitely have heavier rubber on the sides. Cleaning the rim, I noticed I had indeed bashed it, and used some pliers to wiggle it out a touch. New rim tape, new rim strip again, and new tire. Terrible, not able to get it to hold anything. Added bubbly water, still no go. Took it to the air-compressor at work. Nadda! Went to compressor at gas station on the way home - still no love.

The step I am missing, besides it not being a Bronson (I love that name), is having it sit with a tube inside for a few days, which is where I left it now. Might take it out for a spin this weekend too, then hope the bead has settled enough to try sealing in some air. Maybe the Old Rocket Ron would have been a better place to start, microholes and all.
