    Le dimensioni più contenute dell’ attrezzo rispetto ad altre marche, lo fa risultare vincente nella scelta d’acquisto.
    Ottimo materiale, impugnatura sicura e innesto preciso e dolce fra le pinze dei freni in caso di chiusura accidentale quando la ruota è smontata.
    La marca dell’attrezzo ovviamente continua ad essere sinonimo di qualità nel mondo bike.

    This is a quality tool, definitely worth $20. Retracting the piston is important. But so is cleaning around the extended piston using Dot 5.1 and a Q-Tip. Being able to do this maintenance routinely will keep brakes from rubbing. A clean piston can be retracted, and then it will adapt to the brake pads properly.

    Perfect for use with breaking the pistons free if you buy TRP DHR- EVO brakes. Which is a problem. TRP Don’t come broken in, and I took it to shop to repair and they made it worse. So I purged the system, and did it all myself. Now works perfectly with 1 finger breaking. If I had it to do over I’d buy the Magura brakes. Bike is built of the LUNA CYCLES X2 Ludicrous base build, everything but the frame, engine and battery has been upgraded to top quality parts. If I could do it over I’d build from scratch, you can build a $10K bike for $5800 if you know where to get parts. Especially right now due to the release of 2024 Dampers by fox, 2023 Factory Kashima is under $500 on Jenson and my Fox Float X2 Kashima was 299.99. Plus new Fox 2024 dampers are getting not so great reviews. Save money build from Scratch. My next build is Dengfu E82, Bafang M560 motor 750watt Nominal 1000watt Peak, 1008wh 21amphr 52volt Battery. Don’t buy Luna’s Ludicrous because it overheats real fast if you take advantage of power over 1250watts with FW1. If you want a modded motor buy from Watt Wagons, or get the Bafang Ultra motor. We now have 3000watt Mid-Drive bikes out there, which is def worth looking into.

    After bleeding your brakes or accidently squeezing the brake lever with the tire off, having a brake spreader is critical. Yes, you can do it with a flat head screwdriver or a putty knife, but this tool does it quickly, evenly, and definitively- you can actually when the brakes slide back into place. It may sit in a drawer for 364 days a year, but the one day that it doesn’t you’ll be clad that you have it.

    Prior to buying this tool I was using a screwdriver to try to press my hydraulic brake pads back into place which is a terrible idea and a quick was to damage the pads/pistons.

    This tool is not cheap and it’s hyper specialized, but this tool does the job so easily and without damaging the brake pads it’s worth the money. It will also last a lifetime.

    J’utilisais avant cet outil un gros tournevis plat qui abimait les plaquettes, avec cet outil, le problème est réglé. Un peu cher pour un usage personnel mais la qualité est au rendez-vous.

    Very easy to use. Whenever I swap wheels on my road bike, I use this to reset the pistons on my hydraulic brakes to remedy rubbing on the rotors. It’s made by Park Tool which means is very sturdy and well tested for it’s intended use. Has made my life easier during wheel swaps/maintenance

    I bought this to service my hydraulic brakes on my bike. Although people suggest you can use a flathead screwdriver to achieve the same results, you risk damaging the pads and the pistons.

    works well, feels well made. The metal surfaces that come into contact with your brake pistons, is flat and smooth with no irregular surfaces to mar, scratch, or otherwise damage your piston when trying to press them back in the caliper.

    Rather than risk damage to my brake caliper pistons, this tool has been designed for this specific purpose. It might seem like something you only use a few times, but it truly is the right tool for the job. The handle has the right angle that a screwdriver or flat chisel just doesn’t.

    Skeptical that this would work better than a butter knife, but it doesn’t flex at all and has the proper thickness. Worked flawlessly without any of the hassle of my previous experiences.
