Broke on first Use

"I bought this so I can fully dial in my two bikes. After months of no riding because of the harsh winter we had here in the northeast and suffering a really bad crash that left my wrist fractured, and broken ribs, I was excited to try it out. While I was hand tightening the virtual fender to the bike the little flimsy bolt that holds it cracked now I am left with an expensive paperweight. Really disappointed."

Eddie M. (1/5)

Great tool

"What can I say. Makes setting sag easy. Only easier way is to pay someone else. Good quality product that just works. Tons of videos out there to show how it’s done. Just buy one. Your ride experience will be so much better on a bike set up for you, and you’re far more likely to do that work if it’s easy."

Christopher B. (5/5)

Great tool for tuning MTB suspension

"High quality kit with everything you need to accurately set the sag on the front and rear shocks. I was surprised at how far off it was using weight formulas to estimate shock pressure to set sag. After setting the correct sag with the slacker, my bike rides so much better—more active on climbs and plush on the descents!"

Greg C. (5/5)

Works great

"Purchased the Motorcycle starter kit to set sag on my dirt bikes. I've been using a tape measure previously to do this. The Slacker tool makes it so much easier and faster. Using this tool, I feel much more confident in the adjustments I am making and i dont need a second person to assist me. The instructions are very easy to follow and the tool works seamlessly."

Tamas G. (5/5)

Setting Suspension

"I got tired of having to always need help setting my sag so often, I went from 280lbs to 211 now so I had to adjust it every few weeks loosing weight and this tool made it so much easier to do it myself or Atleast with less help than before!"

Jordan A. (5/5)

2 part review

"I love my slacker but my old one broke out of nowhere. Called about service was told to send it in and they will repair. Good thing I ordered another since my broken one has been there for 2 weeks. I love the product but idk about the quality."

Bryan W. (2/5)

Smart tool, seasy to use

"Good idea, smart execution. . Device feels robust, easy to use. Megnet to attach the tool on the rear shaft. You're done realy fast. Some extra self adhisive connecting point for the rope / wire were with the tool. Actualy nothing negative to tell anyone. Only,,,, throw in the battery's when packing the tool for shipping. Than you can get going when you receive the tool."

Ben K. (4/5)

Incredible!

"Makes setting up the slack so easy, especially when alone. And with proper set up slack, the rebound and compression follow so easily and convenient. A properly set up bike makes such a difference, one wouldn’t believe it. Honestly, it’s addicting how rewarding the before and after is, I’m gonna set up every friends bike I can get my fingers an."

Constantin K. (5/5)

Great option, needs some tweaking

"I was surprised how inaccurate the shock stroke measure method was. Nearly a 7% difference in sag percentage on my bike. Which I suspected because I felt like I was too deep in the travel and this confirmed it. Note: this wheel movement measurement is not a holy grail, it’s a starting point to tune from. My 2 gripes are: the temporary fender required ALOT of strength to tighten the swivel point not to move. As soon as the tension loaded string was attached it pulled down. And the axle inserts could be a little larger in diameter. If I dismounted on the brake side, the weight of the device would pull it out of the frame. With the newly revised phone App, I did waste money on the remote but no big deal"
