The hub of the wheel shown in the attached photo is a Shimano RX-100 FH-A550

I would like to buy the chain whip tool and the lock ring tool required to install the 7 speed RX-100 cassette back on the wheel.

For ordering purposes what are the specs of the 2 tools that I would like to buy based on the wheel and the cassette that I have?

Thanks

I believe that to be an either/or style freehub. Either the last cog holds on the cassette which requires 2 chainwhips (or 1 and other methods) or an internal lockring which needs 1 chainwhip and a lock ring tool.

Thanks, dedhed and Bill Kapaun,

I believe that I have the Hyperglide, because I can see a spline wider than all the other splines on it, but I am not sure if it is the “Uniglide compatible” or not. I have seen my cassette removed from the wheel using one chain whip only (or at least, this is what I remember). Would the FR-5 TLP25 be a good tool for removing/installing my lock ring?

What about a Park SR-1 chain whip? On my chainring I can read: ‘Shimano SG for narrow chain only’. Will the Park SR-1 work with narrow chain?

Thanks

You don't really need a chainwhip to install a cassette. You do, however, need one to remove a cassette. The Park one you've mentioned is for single speed chains, better off getting one for 10 speed or more chains to future proof yourself.

Do yourself a favor and skip the chain whip. They are awkward to use and can slip if not set properly. Get a Pedro's Vise Whip instead. Much easier to use, once it is latched on it won't fall off. And no bloody knuckles.

Work gloves are pretty handy in that regard, and will help you get a better grip to boot.

Using the information kindly provided by the Forum members I have placed orders for a chain whip and lock ring tool. Although I like the concept of Pedro's Vise Whip, I went for a conventional chain whip, because I felt that the Vise Whip was too expensive for occasional use.

Thanks to All for the help.

Interesting product. Looks nice, but I've never had any trouble with my (free, home-made) chain whip.

I use cut gloves with dorsal impact protection whenever I'm working around cassettes/freewheels or chainsets, particularly pedals (and don't forget to put the chain on the big chainring!)



They aren't that expensive (<$20), the cost savings from avoiding an ER visit more than makes up for the cost, and they double as downhill gloves!

I use the ER visit in jest, but the last shop I worked at got these for all the mechanics after one skinned the back of his hand removing a pedal. Being a typical mechanic he wiped it off, threw on a band-aid and kept going. 3 days later his hand was swollen to about 2x times its normal size, bright red, and the arm was starting to get inflamed. Yup, he got infected from the cut, ended up in the hospital after he went sepsis. They guy was a shell of his former self the next time I saw him, and had some long-term hand problems.

The shop owner stepped up and somehow got the shop's insurance to cover the hospitalization, and started taking this stuff seriously. Cut gloves, dumping all the chain whips and replacing them with proper cassette vises and Pedro's Vise Wipes were just some of the things they put in place. They even got impact wrenches for pedal removal. The shop owner had 3 stores but he said the cost to implement the changes in all the shops was less than $5k, far less than what the injury was going to cost him. A little protection goes a long ways.

Big plus on wearing gloves! I just use leather work gloves when removing the cassette and especially when removing pedals. Yes, chain on the big ring helps from hand-intimately meeting-chainring teeth. I know I learned the hard way. Funny how experience is the teacher that gives the final exam first. Never had to visit the ER, but ripped flesh and scrapped knuckles sure slows down progress.

i’ve said to myself many times “wow, I’m glad I had gloves on”. I don’t recall many times I said, “I wish I didn’t have gloves on”.

It's called workers compensation insurance and is required by law in most states to protect workers. He probably found with expensive claims his premiums went up and prevention was cheaper than claims.

Worker's comp denied the claim due to the injury not being reported as soon as possible per state law. I know the shop owner was negotiating with them & the hospital and I know he ended up paying a big portion of it, I don't know if work's comp ever paid any of it.
