Ghetto tubeless weight?

I'm guessing the DIY rim strips made from 20" schwable BMX tubes are lighter than stans rim strips.

Is this the lightest tubeless set up?

Is it reliable?

sounds like alot of hassel, reliability might depend on how smooth your riding, tight berms & jumps can cause burps with non tubeless tires run tubeless

we've been running Race Kings, Ro Ro, Ra Ra tubeless with 5g Stans yellow tape per wheel + 11g Stans valves + 1x 60g scoop of ust gloop - it comes in @ approx 76g per wheel when the gloop is fresh (less when it dries up abit!)

(typo)

pics
1. 2x Olympic valves + Purely Custom alloy collars + Hutchinson valve washers
2. Stans 21mm yellow tape @ 5g per wheel with 6cm overlap (sorry no pics of used tape on scales)
3. 60g scoop of Hutchinson Protect Air UST gloop - good for a few months in SoCal

Thanks c'sponge.

I think using the scwhable 20" BMX tube for a DIY rim strip helps against burping because when the tire bead moves the rubber strip moves with it. See the demo of this on Stans website. http://www.notubes.com/moviecompar.php This should also apply to the DIY rimstrip.

I just read that the DIY (schwable) strip is 15g lighter than the stans strip.

thats great

from grumbles on boards i've read, DIY rim strips are okay as long as the valves are treated with care - as they can rip away from the strip in time

good luck

Are you running Stans rims, and why are you using that particular brand of sealant?

mostly DT Swiss XRC & 4.2D rims, but will be using the same method with a Podium MMX wheelset build when the Tune hub shows up

using Hutchinson's mainly because it has no ammonia and It can be purchased in bulk in a 5ltr container from CRC (free postage + no tax) - it should last years

almost always start new tires off with Stans sealant, seems to be the best for getting beads to lock - then after a month i scrape out the rubber snot and then run the tires with Protect Air

i really should work out how much i've been spending on sealant over the last few years - an Eclipse inner tube might have been cheaper!

best

But wouldn't offer the puncture resistance of tubeless. In the long run tubeless is probably much cheaper.

Thanks for the advice and info

The schwalbe BMX tubes are good because the valve-cores are removable and they offer them in presta valves. They also cost a lot less than the stan's strip.

Nice

I thought I'd do a price comparison.

Stans kit for 2 wheels = £44.99 from CRC

Comes with:

• Two molded rim strips with Presta removable valve cores
• One pint of Tyre Sealant with a 60g scoop and spout
• One 10 yrd roll of spoke tape

Ghetto Tubeless using Stans sealant = £21.97 from CRC (items bought separately)

• Two Schwable BMX tubes (from CRC £9.98)
• One pint of Stans Tyre Sealant with a 60g scoop and spout (from CRC £11.99)
• One 10 yrd roll of spoke tape (use existing rim strip if necessary or electrical tape)

There are cheaper 'lightweight' schrader BMX tubes. I've seen them @ £2.99 on CRC though not currently in stock. Cheaper sealant is available too, you can even mix you own 'home brew' sealant. Apparently Stans gunk is really good though.

I currently have ghetto tubeless on my downhill bike and it is doing great. Its probably not the lightest or most sleek method, but it's low cost and after numerous jumps, drops, roots, etc. it has held up amazingly.

You could ghetto tubeless three or four bikes thanks to tubes like Schwalbe's for the same price tag as one Notubes conversion kit. Those rubber rimstrips of theirs are ridiculously overpriced.
