Product does what it's made to do
The bikehand wrench is built very sturdy and worked perfectly. I used it on a an upgrade for my road bike when I changed cranksets.Now the important question:Do you know Jesus Christ as your Lord and Savior? I encourage you to honestly, and humbly, consider the claims of Jesus Christ and respond to what the Bible testifies about Him.I. Here's the Dilemma:We are all sinners by nature and by actions."For all have sinned and fall short of the glory of God." -Romans 3:23Our sinfulness separates us from a proper relationship with God."For the wages of sin is death, but the gift of God is eternal life through Jesus Christ our Lord."- Romans 6:23II. Here's the wonderful solution."But the gift of God is eternal life through Jesus Christ our Lord." - Romans 6:23b"But God demonstrates His love toward us in this, while we were yet sinners, Christ died for us." - Romans 5:8"If anyone be in Christ he is a new creation, old things have passed way, behold the new has come."- 2 Corinthians 5:17Jesus Christ sacrificial death on the cross, burial, and resurrection provide real life for us if we'll surrender our lives to Him. He reconciles us to the Father and gives us a new life. A life to be lived in devotion to Him and in proper respect toward our fellow man.III. The receiving of this ongoing relationship with Jesus Christ."If you confess your sins, He is faithful and just to forgive you of your sins and cleanse you from all unrighteousness." - 1 John 1:9"If you confess with your mouth the Lord Jesus, and believe in your heart that God has raised Him from the dead, you will be saved. For with the heart ine believes, resulting in righteousness, and with the mouth confession is made unto salvation." - Romans 10:9-10"Whosoever shall call upon the Lord shall be saved." - Romans 10:13I encourage you to surrender your life to Jesus Christ, embrace His work on the cross as your means to have eternal life, and begin your ongoing relationship with Him.Find a Bible believing church that makes much of Jesus and loves on people as Jesus instructed.Get in God's Word and let God's Word get into you. This will help you grow in your ongoing relationship with God.Blessings

The tool fits and works as intended
The tool fits my Bottom bracket Shimano SM-BB52. Great tool at a great price.

Perfect for16t lockring brake rotor
Worked great to tighten a disc brake rotor locking with 16 external notches. Others complained the handle was too thick and got in the way. I didn’t find it to be a problem and had plenty of space between handle and rotor. Haven’t used it yet for BB removal, but machining looks good.

Decent Tool - Good Value
I've only used the Hollowtech II end of this wrench - but I've used it a number of times. This wrench is decent quality - seems well made. It doesn't have the greatest finish - and the edges around the openings almost have a little flashing from the stamping/punching operation...which could have been ground down a little in manufacturing. But these details may not be important to you. The tool is fully functional as is. and has a nice grip sleeve (feels sort of like silicone). Good value overall.

Good tool, not so good tool user.
Very well made. I still could not remove my trike bottom bracket, but not the fault of the tool, rather lack of strength in this 76 yr old’s arms.

Surprisingly Great Quality
Great quality, heavy in the hand and can handle BBs of four different sizes. Helped me remove an incredibly stubborn BBR60 bottom bracket from my favorite Pinarello, which I couldn't get out with a standard wrench and BB adapter.

Does the job
Purchased this to remove a sram gxp bottom bracket. Worked like a charm no fuss no muss. Seems sturdy enough to last a lifetime. Will be added to my growing set of bycicle tools. Cheap and solid option.

Solid. Good addition to your kit
I like it. Heavy duty and doesn't require a socket or other handle
