Do you really need a chainwhip?

Can't you just wrap the old chain around the cassette and hold tight?

[WheeliePete]

@AndyK243 Yeah, you need the chainwhip for the leverage. That lockring should be on pretty tight. In the video it was pretty loose because I'd been shooting the footage over and over. In an actual application you have to put some force into unscrewing the lockring cap and you'll need the leverage of the chainwhip handle to hold that cassette freehub still.

@WheeliePete i have done it without a chain whip (used a tea-towel and held tight) on my Dawes road bike. I checked with a reputable bike shop and they said that if u have to put the quick release over the tool its on way too tight, understandable, there aren't very many threads on that ring... Good video btw

[WheeliePete]

@4dread5 Putting the quick release through the tools has nothing to do with the lockring being on too tight, it's about not having the tool slip out when you put a wrench to it. The spline engagement is not very deep on the FR-5 so if you are trying to hold the wrench in one hand and hold the chainwhip in the other while balancing the wheel on the bench you can eaisly get off kilter and pop the tool out of the lockring.

[WheeliePete]

@WheeliePete continued. from above... by running the QR skewer through the axle and the FR-5 tool you eliminate the possiblity of the tool slipping out of the splines on the lockring cap. From my 20+ years of professional wrenching I can tell you that you want that lockring on there tight. Trust me, the first time you have a lockring come loose in the middle of a race or a big ride out in the middle of nowhere you'll wish it had been on there tighter.

Thanks, nice video, but your using the wrench backwards when taking off the nut. You should not put pressure on the movable jaw.

[WheeliePete]

@francedad Yes, I know, I know...but let's not be too picky here. We're not talking about a 400# torque value.... :-) When I was working in shops we'd always ask for the "Fits-none Strips-all" when we wanted someone to hand us the adjustable wrench...lol

Good video.

I recently got rid of my money-pit car and bought a bike. My first bike in 20 years, so I'm just seeing what's what. Can't wait for something to break because they look much simpler to work on than cars :)

Hilarious. Or the "Polish Air Wrench" (a hammer)
