what happened to the bearings and grease

[@duratoke]

4:29 "A little dab'll do ya!" Commercial for Dippety-Doo hair gel from the early 70's maybe. I'm that old and I still ride a bike, wtf?

[@asepganteng9870]

What is the type new body freehub 8 9 10 speed..? Thanks✌️

[@kevinborovsky3558]

Wow how did you keep the ball bearings from going all over like when I take my axles out. Good video keep them coming cheers

[@JimsObsessiveCyclingDisorder]

On the non-drive side there was a cap, and gravity helped on the drive side. :) Thanks!

[@duratoke]

Magnets! Well it sure as hell helped with the old style, damn there must of been about a hundred of those little tiny things!

[@joeria3276]

Hi great helpful video! Only have one question: Shouldn't your wheel axle get wider to do this? Hasn't the whole wheel become slightly wider with the 8speed freehub? I want to do this too but am afraid it will be too wide for my frame.

[@JimsObsessiveCyclingDisorder]

Normally, yes but the old 7 speed hub had a lip at its base that the new hub didn't so I got really lucky.

[@brians8607]

Some of the old 7 speed cassette hubs are spaced for 135mm drop out width.

[@johnjavier36866]

nice commentary made me chuckle a few times. and very nice and helpful vid.

[@JimsObsessiveCyclingDisorder]

Thanks!

[@M3garage1]

nice video jim keep it up.

[@JimsObsessiveCyclingDisorder]

Thank you!

[@hilltopper600]

was any redishing required, did rim center the same

[@wadelockhart9459]

Not a reply, but a question> What was the over locknut dimension of your hub? 130mm?

[@ifffopfmn]

If you need to increase the spacing from 130 to 135 yes you need to redish. If it's already 135 you're fine.

[@dannyberndsen66]

Nice video Jim! Did you have to redish the wheel because of the difference in length between the freehubs?

[@JimsObsessiveCyclingDisorder]

No. The total width is unchanged, just the new hub body doesn't have a "lip" at the bottom.

[@LaserFrennox]

Hi Jim, what was the part number for the new free hub body you used? Great video

[@JimsObsessiveCyclingDisorder]

Hi! The one I used is fh-m760.

[@christopherguzzi1316]

Did you have any issues centering the wheel on the bike? Adding a wider hub would offset the wheel further to one side.

[@JimsObsessiveCyclingDisorder]

Nope, it fit like a glove.

[@BasicUtuberNo.1990]

Was there a spacer behind the hot body were they different which one did you choose to use?

[@JimsObsessiveCyclingDisorder]

The old hub had a built in spacer. The new one did not.

[@kingpey666]

Great video, did you need to re-dish the wheel?

[@JimsObsessiveCyclingDisorder]

Nope. The old hub had a built in spacer/lip which the new one lacks. That lets the 8-10 speed cassettes fit without any other mods.

[@iosifsramec4848]

very helpful

[@JimsObsessiveCyclingDisorder]

My pleasure!

[@alfred576]

Hi Jim thank you for the video. If I upgrade my freehub from 7 to 9 or 10 do I have to replace the levers as well on a mountain bike? Currently my rear cassette lever goes from 1 to 7. So how do I go into gear 9 or 10? Alfred

[@JimsObsessiveCyclingDisorder]

Hi, yes, you will need to upgrade your shifters to accommodate the number of gears on your cassette. Also, most 7 speed cassettes (as opposed to freewheels) are on hubs designed for no more than 7 speeds, so check first.

[@johntanchin2545]

hi, would you think i can do this with a Shimano Exage FH-HG50

[@JimsObsessiveCyclingDisorder]

Hi. I am not personally familiar with that model. If it is a conventional hub (seems likely with "HG" in the name) I would think it is a good bet.

[@johntanchin2545]

it's actually a vintage one which i got from the mid 90s. the FH and HG hoping they mean freehub and hyperglide. thank you for the response!

[@gabvaldez6663]

Is it possible to upgrade from 7 to 10? And what size of free hub is needed to upgrade to 10 speed? TIA

[@JimsObsessiveCyclingDisorder]

Hi. If you replace a 5/6/7 speed hub body with an 8/9/10 speed hub body, you can do so.

[@sojusojux5289]

Just decided to buy a new hub to upgrade 10s cassette hahaha , thanks

[@fachryfathrurahman2673]

can i do this with acera x m290 free hub?

[@JimsObsessiveCyclingDisorder]

I'm not familiar with that specific model, but as long as the replacement hub shell is compatible I would imagine so.

[@randomthoughts8346]

hello what i need if i upgrade from 7 to speed ? shifter cogs chain rear (Rd) is that enough ? or plus rear hub axle?

[@JimsObsessiveCyclingDisorder]

If you have a freewheel you can screw on a new one with 8 or 9 speeds. If you have a free hub, you will need to replace the hub, or the whole wheel, and a cassette with the number of cogs you want, and a shifter. I either case you will need a rear derailleur and a chain sized for the number of speeds (8, 9, 10), and a shifter.

[@rwest6389]

Thanks 🐉🐉🕊️🐑

[@JimsObsessiveCyclingDisorder]

You are welcome.

[@andylos1532]

Where are the bearings (balls) in this video? It doesn't work.

[@JimsObsessiveCyclingDisorder]

Hi, the axle has standard cup and cone bearings. They were in good condition so I left them alone. The freehub has internal ball bearings. Since this one was brand new, I left it alone as well. :)
