Sunlite Twinhead Pump Hose Kit, 860mm, Black

I bought two of these kits to replace worn heads on an old Nashbar and a Topeak Joe Blow Turbo pump. The Nashbar pump came with a head with two separate openings for presta and schrader valves facing the same direction. The Topeak pump had a smart head with a single opening that was supposed to fit on both types of valves. With time, both heads started to lose their seal, especially on tubes that are not fully threaded. I also tended to lose a fair amount of air when removing the head. I thought it made more sense to have separate heads for each valve type, so I bought the Sunlite Twinhead pump kit. Installation was straightforward. For the Nashbar pump, I removed the old hose by loosening the collar at the base of the pump. I then removed the fitting that was at the end of the hose and slid off the collar. Next, I slid the collar onto the new hose and inserted the fitting into the end of the hose. The fitting has a bulge in it is held down by the collar and keeps the hose from flying off under pressure. The last step was to hand tighten the collar onto the pump base. The Topeak pump hose was attached to the pump at the pressure gauge. To remove it, I loosened the collar and pulled it off. There is no fitting in the hose because the bulge is part of the pressure gauge. I put the old collar on the new hose and then pushed the hose onto the pressure gauge. The last step was then to hand tighten the collar onto the pressure gauge. The new hose and head kits works great. The gray side is for presta valves and the black side is for schrader valves. To clamp the lever onto your tube move the lever away from the side you are using. When you have reached your desired air pressure, move the lever to the center position. I was impressed by how smoothly this head works. My old heads lost a lot of air in the process of removing the head from the valve. With this pump head, you just have a tiny puff of air that escapes. I wish I would have found this product years ago.

I've used these pump hoses/heads on several old bicycle pumps, and they breathe new life into them! The flip-switch that accommodates Presta and Shrader works very well, and this set makes for a really effective and reliable replacement to pump hoses that are designed specifically for one type of inner tube valve.

This product works great, the lock mechanism is easy to use, seals tight around presta stem!

It took a bit of fitting to make sure that all the connections were able to be attached to the Giant pump. It did work with some creativity. so far it is working well and is a lot cheaper than a new pump.

I have a Schwinn 5 in 1 which has a tandem Schrader/Presta pump head where the connectors are side by side with the Presta being on the inside. It also has the clamping lever on the back of the head. Call me stupid or whatever, but the valve core stem on my latex tubes kept getting bent after a while and would eventually leak air. I didn't want to have to keep changing valve cores. This Sunlite pump head solved my problem! I'm not sure why the Presta stems were bending. It was probably a combination of both the tandem head design and the way the pump head locking lever locks. The Sunlite's the hammerhead style pump head design allows me to apply force directly behind the pump head as its going on the valve stem and the locking lever being on the side of the head, rather than on the back, minimizes or prevents side forces as it's clamping the valve stem. In any case this Sunlite replacement hose has made me a happy biker. It's thicker than the stock hose so it doesn't fit in the storage clips on the handle. Nothing a velcro cinch strap can't cure though. Also, it's longer than the stock tube which is good.

I have bikes with both Schrader and presta valves but have a schrader only air pump. I would have to use an adapter to inflate and check pressures each time I ride. The hose on the air pump was also a bit shorter than I would like. I would have to take my bike off of the work stand and place it on the floor for the hose to reach. Overall it was a pain in the butt to use. Rather than buy a new pump, I decided to try this hose kit. It came quickly and installation was a snap. I simply unscrewed the hose retainer on the pump, removed the old hose, then inserted the new hose and tightened the retainer. To make the hose more pliable for installation, I held the end over a flame for a few seconds to soften the rubber a bit. The hose is long enough to inflate tires while the bike is still on the stand, and the release valve works good. By pulling on the inflation nozzle while releasing the lock lever, I found that only a minimal amount of air loss occurred. Seemed like much less air loss than trying to remove the old pump nozzle.

Works great

I find this type of hammerhead chuck easier to use than the one- or two-port universal heads which require more room above the valve. My pump with this head on it is the one people borrow when they need to pump up a small-diameter wheel with a lot of spokes. With a little dexterity this chuck can be put on a valve with one hand and partially locked, then fully locked with two hands; this isn't possible with the other types of pump heads.
