Crankbrothers Dunarri Speedier Lever , Black

I love this tool! No more levers for me. I keep this in all my saddle bags. Absolutely the best for removing and installing bike tires, especially when trail riding.

Product worked great! I was having a heck of a time trying get my Continental Terra Speed on my rim. Bought this. It worked within five minutes. I had to use this with a tire lever.

This and a spray bottle of soapy water will get your tire change down to pit crew times.

This lever does work and is better than traditional levers. With that said it is a bit awkward in terms of hand position and as noted by others the hook for mounting is too thin and looks like it will break easily. I bought this and a tyre monkey at the same time to try both and recommend the tyre monkey hands down. It may be 3x the price but the tyre monkey is much easier to use and I think will be much more durable.

This tire lever is AMAZING. I was skeptical on ordering, so as soon as I got it I immediately tested it on the hardest tire/wheel combo I have ever encountered. I literally broke 4 of my favorite levers getting these set up, and it took 30-40 minutes of hard, frustrating work to get the job done. (Typically to get a tire off, change a tube and remount a tire it is about 1.5- 2 min, rarely more than 5 for a difficult tire and/or rim). I was very nervous to do this test, as I never wanted to experience what I went through to mount these again! A quick look at the lever, and what wasn’t clear in the pictures was immediately obvious in how to use the product, 1 end to remove a tire, the other end to mount the tire. First the removal- which took about 10 minutes with a very good set of levers. Using just one of these the bead was out, off and tire/tube removed in under 20 SECONDS! I could not believe how easy and fast it was. This would be very easy for most women riders I know. Next up mounting- this was unbelievable hard with standard levers, particularly the last 5-6 inches which were crazy tight. Switched tool ends, snapped the tool into the wheel bead, and pulled the tool around the wheel. The tool pushes the bead of the tire over and into the rim as you go, and makes it virtually impossible to pinch the tube, which is particularly great with latex tubes, which is what I use. Up until the last 5 inches it was incredibly fast and easy, but as I got to the crazy hard part it there was definitely more resistance, and I had to use my left hand to assist in pulling the bead up. For me, this was slightly hard, but very manageable. 30 seconds and tire was mounted! I absolutely could not believe. Just to confirm it was not luck, I removed and remounted the tire 3 more times, each one similar or better time than the first effort. I went from the despair of feeling I was going to have to give up on what my research showed was far and away the best tire for my wheel, to the elation that $ 8 bucks can allow me to deal with ANY tire wheel combo quickly and reliably. For easy tire/wheel applications there are a lot of good lever options, but for difficult applications there is nothing better than this tool. While it is light, it is a little bulky, but absolutely worth finding a way to add it to your kit!

First time using this lever was on my lap in the front seat of a support truck after I caught a pinch flat at mile 62 of the FDNY 343 ride. This lever made it extremely easy to change the tube for the 28mm tire on a rim that came with 23mm tires. I was able to rejoin the ride before the next rest stop. I would not hesitate to buy this lever to have at home. While a little more difficult to carry on the bike since it’s larger than standard tire levers I carried mine using the outside Velcro of my gripper bag and had no fear of it falling off. This will become part of my standard kit since it brings so much value.

Have been using this for two years, at least twice a year to add and remove spiked ice tires It is a must-have for tight wire beads. I juat uaed it to swap out my fat tires.The somewhat sharper edged install lever and brass-knuckles like grip make pulling the bead up, out and off the rim a lot easier than the small plastic tire levers - without scratching or damaging the rims that may happen using the big metal Park Tool levers (which are a must for really stiff beads).The groove in the tool to install is really handy to slide the bead in the rim without pinching the tube. Again the grip is key to maximizing leverage.For really deep tubeless rims like on my 29er, or even thick wire beads like the CST Toboggan pictured here, this won't be enough. For that I use the long metal Park Tool TL5 levers and the Koolstop grabber for the last few inches of bead.

The media could not be loaded. I purchased this after being stranded on side of road because I couldn't easily remove and install my super tight tires/wheelset combo. When I did finally get the tire installed, I had pinched my tube causing a flat.I tried this - once I really understood how to use it - takes a little practice as they have a slightly different design/approach than other levers, this things works wonderfully. And, I also tried it on not-so-tight installations - and that was ridiculously easy.**Only issue is that its bulkier than normal tire levers but should fit in most saddle bags - it would be great if it collapsed. Total game changer for me - and I also have gained some respect fro CrankBrothers as a company since this is "revolutionary" design - that is, they took a really different approach in designing these levers vs just tweaking the true and tired design that everyone has.See my video review.
