Collection: Hold Fast Cycling Tubeless Valves and Tape

After messing with syringes for sealant that would eventually clog or in some way fail the simplicity of this is a breath of fresh air.

Perfect tool for filling sealant

Works amazing!

I've tried many methods of adding sealant. Saw the Straz funnel while perusing the interwebs and thought "what the heck". I purchased 2, one for myself and one for the only guy that works on my bikes at my LBS. I used it for the first time last week and OMG! No mess and easier than any other method I've ever used. My guy and I wish it had one addition...a plunger like what's used in a Shimano bleed kit. That way we'd be able to measure more accurately how much sealant we're adding. I'm going to try a plunger this weekend. He's going to look into 3D printing a solution for us. Straz, something to think about.

Love the weight and self-centering aspect of this tool. Makes for a sure & smooth extraction of any Presta valve.

Such a handy little tool. Works so much better than a syringe for filling tires with sealant

Works well with Reserve Fillmore valves. Nice clean solution to what can be a messy maintenance task.

Gave this as a gift. It passed the test. It's a keeper. Going to get one for myself.

Must have… works great with the Reserve Fillmore valves. Less of a mess and saves sealant. I used it with Orange Seal, zero issues.

So simple, yet so perfect. A great small addition to my toolbox,

No fuss, no mess! Straz even quickly sent a new one after USPS smashed the first.

This works well. Money well spent IMO.

Funnel works

Works super easy! And I like supporting a small business. I would absolutely buy another one if I loose it or give it away to a friend.

It works well
