A premium tubeless tire sealant? From the technical specs, yes, Velowürks seems to have come up with a great formula. But first, their new floor pumps.
On the top, both literally and figuratively, is the Prime, followed by the Indy and Element. All feature long braided cover hoses, oversized displays, rebuildable bodies, and extra tall shafts so you won’t have to hunch over to pump up your tires. Where they differ is in materials and the finer details. Both the the Indy (left) and Element (right) have a steel shaft with plastic handle, dual valve (Presta and Schrader) head, 160psi/11bar max and their triangular base. The Element gets a pressure bleed button on the valve body to help you fine tune tire pressure, a longer hose (not shown on this pre-production floor model…it’ll be the same as the Prime), 3″ gauge and an industrial grade HNBR rubber plunger.
The Prime goes even further…
Getting all the same features as the Element, the Prime upgrades to an alloy body that’s hard anodized inside and out, steel handle and a cast aluminum valve head with investment cast alloy lever.
The taller shaft means more air is pushed into the tires with each stroke, making your job a little quicker, too. The wide triangular base keeps the pumps steady. Each foot pod has non-slip, non-scratching rubber feet.
Max pressure bumps up to 250psi/18bar on the Prime. Retail is $130, which is inline or better than many other “lifetime” floor pumps on the market.
The new Velowürks sealant comes in two versions, one for tubes and one for tubeless. Both are latex free and use a low viscosity blend of emulsifiers and microfibers to flow quickly and clot at the holes, up to 3mm. And they have an operating temperature range of -30ºC to +70ºC (-22º to +158º F), making them perfect for anything from winter fat bikes to summer racers.
The tube sealant has an in-use life of two whole years, virtually a set-it-and-forget-it product. It’s available in a self-use pouch to cover two tubes, or a shop-sized pump that makes for a great upsell service.
The Tubeless Tire Sealant has a still very respectable 6-month in-use life and comes in a 1-to-2 use 90ml pouch, a 500ml refill pouch for multiple bikes and a shop/team sized pump holding two liters. The low-temp capability means it should also hold up to quick inflations with C02.
