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."

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"

Best tool!

"This thing is so awesome and makes like way easier!! I love telling everyone about Slacker & showing them just how easy it is to tune your suspension with no assistance!!"

VeronicaVirginia S. (5/5)

Everyone with suspension needs one of these tools.

"Tool is simple to use, comes with everything needed for motorcycles (except batteries - wish there was a lithium rechargeable device version). Phone app works well, no issues. Very accurate and enhances safety. Purchase to do it yourself and save money from the stealerships. Only thing noted that I hadn’t seen mentioned is if you have rear axel spool sliders (for paddock stands) you may have to remove in order to attach this earth magnet to your rear axel. You may not be able to use your rear stand if spool has to be removed. Great price, great product, highly recommend to other. Device that pays for itself! Awesome."

Awesome Tool/ Great Customer Service

"I placed an order on a promo deal that said it included everything plus the case and remote. The kit came, but no remote. Reached out to customer service who kindly sent the remote after a few short questions. The tool is super straightforward and easy to use and if taken care of should last any amount of slack adjustments performed from moto to mtb!"

Zac H. (5/5)

Finally. . . . . got to accurately set my sag

"With the Slacker, I am finally able to set my sag on my motorcycles by myself. and do it much more accurately too. Now the wife doesn't have to come out in the garage and help me. That alone was worth the cost for this specialized tool. . . ."

Paul G. (5/5)

Exceptional

"I have used this on all three of my bikes. I have been setting up suspension manually for 30 plus years. Trying to do this solo is always tricky. This tool made it a snap. I did find my butt dyno suspicions confirmed that I need to drop the preload slightly on the front of one of my bikes and found the rear suspension out of range on my other big bike I don't ride much. Very easy to use, the app is pretty seamless so I can just use my phone to remote view."

ken c. (5/5)

"I paid over 100 ILS for shipping and received a service that feels worse than free economy shipping from China. The package missed the estimated delivery date, tracking updates have been almost useless, and there has been no clear information about where the parcel actually is. Charging premium shipping prices while providing this level of service is unacceptable. Very frustrating experience."
