Very interesting video, thank you very much. The good side for dismount the axle is the left one (non drive side) 😉

[@alexandrumihailescu2252]

One thing you should be mindfull of is freehub compatibility. Most shimano freehubs can be undone with a 10 mm Allen key but some require different tools and the splines will differ from model to model as well. Some different hub models will use the same amount of splines and mounting system but will require some good research before hand.

[@radiocontrolled9181]

My 7-speed Shimano freehub body slides out nicely. I just have to undo the cassette lock nut, remove the cassette and then slide the freehub body out on the shaft. Very easy to remove and clean/service/replace.

[@peterkakas3432]

If you do it this way than the wheel will not be centered in the frame! For total perfection You have to center the wheel with the new freehub body

[@leifcian4288]

Dish the wheel you mean?

[@b-lopez394]

SickBiker, What I was taught when I was taking automotive classes before I became an Automotive Master technician is NEVER use a magnet for removing bearings. There is a possibility that the bearings will get magnetized and attract worn metal shavings. This will cause the bearings to self destruct.

@@peterjv8748 hey man, i need help.. please if you know answer me back.. i am doing a 7speed shimano exage 126mm dropout rear wheel with freehub body upgrade to 10 speed shimano tiagra. i bought FH-m525a freebody that comes from deore rear hub and now my question is which cone i need so i can put the new part on my axle. do i need the whole right nut parts that come with the deore axle or i can complete this with my old exage right side nut parts. also i am planing to use my original axle bolt and plan to just put the wheel by litle bit of squeezing since it will most probably be 130mm after the whole replacing and locking is done?

[@peterjv8748]

@@serafar Several reasons I don't think it will work. Spacing, dishing would be a struggle even for experienced wheel builders. Is your frame steel? If so, I think you'd be better off getting a whole new wheel. One with 130mm O.L.D. spacing will be hard to find. So cold setting the frame to a 135mm rear dropouts is probably your best bet. 135mm hubs/wheels are plentiful and cheap.

[@serafar]

@@peterjv8748 yes it is steel frame and it goes streatching to 130mm no problem. I've read a lot on many forums that you can do 10 speed up. with 130mm hub rearangement from 126mm hub like my exage is. Ill try anyway before i decide if ill need to buy a new 130 or 135mm hub. Point is this road bike has all exage groupset so i plan to reuse the hubs and the crankset with the breaks to keep the retro flavor.

Nice one, I have an old set of lovely Mavic 231's with a 7-speed Deore LX hub, and having an 8-speed cassette would really open up the gears that I could use in a 2 x/ 1 x scenario, and I could carry on using my old 1989 Deore II thumbshifters (they have a "secret" 8th click)

Nice useful video. I have just replaced my MTB 3x7 Shimano type freehub body (which had 3 pawls and one of them failed because the freehub body cracked where it sits) with a new similar 3x7 freehub body, but with 6 pawls. I was not sure that it would work but it went in perfectly and engages like a dream. I love how today's modern promotional media has managed to convince the people that going from 21 speeds to 18, 11 or 10 speeds is actually an 'upgrade'. LOL thank you but no thank you. I'll stick to my wider 21 gear range and will not downgrade to less gears.

[@valerioviti6630]

With 3x7 you dont have 21 speeds, you will only use 11 or 12 of them. So 1x12 is same but less weight 🙃

It is to be said that often 10-52 tooth cassettes have the same range as 21 speeds, i like 21 speeds and they do have a good amount of pros, like the quick downshifts but 12 speeds are lighter have less chain falling off type problems as well as a cleaner cockpit and less service needs, it really depends on what you prefer

Yes, but you will have to redish your wheel (loosen on the left, tighten on the right). It will make the difference in spoke tensions even greater ;-(

Personally I want to do the opposite. Makes for a stronger rear wheel. Lately I've been "downgrading" to 5 speeds. There's almost no dish!

not required if he's using the new axle

@@justasducinskas633 You might be right but I don’t think so. I’m still riding my ‘86 Zebra and did all this over the the years on it as I upgraded. The important measurements start at 4:56. Look carefully at 5:38 and the cone stack height. The 8+ speed cone assembly appears to fall about 3mm lower but is thinner. As he says, one would have to pull the the stays apart to insert the wheel, that difference has to go somewhere. I’m pretty sure the dish would need 2-3mm adjustment.

[@terenceprieto3964]

please, the internet is full of old information about freehubs compatibility that are no longer true. since fixing bolt is not 10mm for all the rear hubs, the interchangeabilty of the freehubs is tied to the rear hub of the wheel (and the widht of the fixing bolt and the axle) we can not use an xt (today) freehub in a deore rearhub (14mm fixing bolt vs. 10mm fixing bolt). we can swap freehubs when they are compatible with the fixing bolt to attach to the rear hub. maybe a video with freehub compatibilty by / between series (share fixing bolt widht) be helpfull. i.e: today a 20º click freehub is nice for you. tomorrow you need 10º click... ok, swap the freehub and go away... errrr. nope today. what's your rear hub axle widht? ok, then you can go for one or other freehubs. thank you.

and what about the matters with the chain and chainring? As all we know the width of a 7 speed chain in not the same of a 8 or 9 or 10 or 11 speed, so you should inform that after that you must update also the chain and chainring, am I right?

Very nice information bro 🚲

[@oscalcmen]

did you measure how deep the lockring goes in to the freehub body (how many turns are needed to tigthen the lockring to 40Nm)? I did the same and with a 11 speed HG Deore cassette and a 34.9mm (a standard) freewheel but mine just need 1.5 turn to reach 40Nm, that I believe is not enough a longer lockring is needed. with a 135mm frame there are no issues about spacing.....

If you open drive side cone an nut, then its harder to get the renches there to adjust the play. Have done it bothways.

[@lobuxracer]

In my experience, you can disassemble from either side but the drive side is definitely harder to remove. To reassemble, you have no choice but to fix the drive side and adjust from the non-drive side. It's also a whole lot easier to use the squeeze method with one hand on the locknuts instead of two hands and the wrenches at wide angles, and if you really want to make it easy, use one 15mm cone wrench and a 17mm socket wrench so you don't slip and marr the flats on the 17 when your cone wrench slips.

Yes, 9, 10 and 11 use the same length freehub. The space between sprockets is changing so you can fit more sprockets. That's why you need a different chain. Because chains for more gears are narrower.
