Park Tool FR-6C Sprocket Puller Tool BMX 4 Notch

Fits and works well on many 4 and 8 slot freewheels. Old school and mid school bmxers need one of these!

Worked perfect, not cheap quality. I used it twice and it will be last many uses, unlike junk quality

Worked great!

I use this to remove the Shimano mx-30 freewheel as well as other freewheels with the same 4 notch dimensions. I hooked it up to a ratchet wrench by way of a 25mm socket.

Quality park tool of course but it didn't work for what I needed. I had to replace my freewheel on my super deep v origin8 wheel . The design doesn't allow the tool to reach the freewheel , it won't go over the longer 120 mm hub bolt that these type of wheels use . Although it's the correct fit for these types of free wheels it is not designed for these types of wheels. It's specifically made for bmx wheels which have a very short rear bolt width. However I made it work this time around but I had to loosen all the lock nuts and remove the shaft . So while I was at it I decided to clean and repack my rear hub so all us well .

I bought this to remove the castle nut on the rear subframe of a Honda Goldwing GL1200. It is a good fit and helped spin the nut off, without having to order the $200 tool from Honda. Not what this tool was intended for, but it did the trick!

This is exactly what I needed to swap the old hub on my fixed gear bicycle. It’s got some weight to it and will likely last a very long time. In the end, I decided to purchase a whole new set of wheels, tires, and a brand new hub to change the overall appearance of my bicycle. This tool came in handy when I needed to install the new hub on the new wheels. Although you won’t find yourself needing this tool very often, this is still a tool you should have in your tool box to prevent / avoid damaging your bicycle wheels whenever you need to change out your hubs. Make sure to measure your hubs before moving forward with this purchase, or you’ll have more down time with your bike. Many of the tools and hubs look very similar, but they definitely come in different sizes. If this hub tool is the size you need for your bike, buy this one now! You’ll be happy you did.

was able to take freewheel apart to clean bearings, durable steel, works well

This is a hardened steel tool with well engineered pegs. The only problem is it’s not quite deep enough ir wide enough at the center to go over the inner axle bolt (see picture), I used a tapered step drill to widen the centre in the right place. Unless you do this, or remove the inner axle the tool won’t sit flush and you bay damage the slots on the freewheel. I suggest using the outer wheel but to hold the tool in place so you can use a socket with a breaker bar to remove the freewheel easily

Embout solide et bien ajusté.

perfetto !

Solides Werkzeug.

Park Tool es calidad, pero hay cosas en las que no se aprecia tanta diferencia. Funcioinar funciona bien, ojo que hay otra herramienta similar para otro tipo de piñones, fíjate que valga para tu piñón
