مفك عجلات الدراجة الهوائية

good but using only one

You can use a 22mm spanner or a 1/2 socket. I ended up using the 1/2 breaker bar & rust penetrant, it was fairly stubborn, chain whip is a must also. Once loose just screws off, not really needed to screw on. Bought click and collect at short notice as amazon product was not as described. service excellent

Tool too big, incompatible with shimano, I had to blend it to fit, if you have machining tools you can blend it, thou waste of time
