This is my second order. The tubes are as reliable as any I've used, regardless the brand name or price. Very satisfied.

For a while until SLIME tubes come with a valve long enough for all the new deep rims out there now, these combined with the SLIME you can add through the removable valve core are the cheap quality answer to all but weight weeny grade puncture sealing tubes in new deep rim wheels. You can but probably won't put these in your Zipp 808s. 48mm is just long enough to fit the Velocity B43 rim(about the deepest there is in metal rims) with enough for the air chuck. You may have to hold it on for the last few psi if yours is loose fitting. Or just leave your little schraeder adapter on instead of the black cap. Anyway:

1. Get the proper size tubes for your tires & wheelset. Remove the removable presta valve cores(these are the only long valve tubes that have this) using a smaller adjustible wrench on the two flat spots ground on the core. Careful if you use pliers not to booger up the threads, over tighten or bend the tiny valve pin by doing this with it open. Don't torque the stem off by holding the other end where the rubber tube joins either. This stuff should only just be finger-tight for good a seal.

2. Squeeze in ~2oz of SLIME for rd, ~3oz for medium commuter tubes, ~4oz for MTB tubes. Please get the SLIME from the hardware/department/auto store by the L instead of by the 8oz in the bike store. Much cheaper and it doesn't 'go bad'. Support your local bike store by buying other things you can only find there instead of bulk marked-up ubiquities.

3. Install your Q Tubes with THE most complete, relevant and all around best instructions anyones ever printed on the back of a tube box. And I worked at bike shops.

Oh and throw out your 5lb 'puncture resistant' tires and tubes, your PITA 'tire liners' and all that other crap. None of that stuff will SEAL a puncture(or multiples) up to 1/8". Nothing PREVENTs them better than vigilant riding with proper tire pressure.

Now go ride safely with manners now that you have piece of mind and more $ left over.
