@RJ The Bike Guy - does the chain also need to be changed to match the width of the cassette cogs? In which case wouldn’t the crankset also need to be changed?

awesome, RJ! remember my 1983 Trek 520? Im looking to upgrade my current 2x8, you just confirmed my belief of it being possible to jump from from 8 to 9 or 10. Thanks, man!

[@whidbeyhiker4364]

Pro tip, you should be able to see the spacer without taking it off. In other words, if the cassette is 7 speed and the cassette is all the way against the flange of the freehub with no spacer then it is not 8 speed or higher compatible. Just look for the spacer before going to the effort of disassembly and measurement. The reason I mention this isn't to dispute the poster but if you are out "used bike shopping" or see a bike at a garage sale quick tips to identify parts can save you from making a purchase that won't benifiet you.

[@laverdadtriunfa]

That is a good point, but in my case, it was the right bike until I sent it to colombia, and now I have to get more and higher gears , then is less expensive than buying a new bike. 😊

[@erw91]

Thank you mate very helpful

[@JuanitoSu]

great video! Exactly the question i had in mind. Now if there was some sort of database where we can look up a specific model bike and from a certain year and quickly learn what (if) could be upgraded to, that would be fantastic!

[@grahamlane131]

you have covered the details in other videos but i add this for people viewing to source first time information: moving from a 7 to 8 cassette should have little issue, from nine to 11 you will expect to replace as well as the cassette, the chain, chain ring, & both front and rear mech's.

[@mxkcrm]

I have an 830 lol have you have a chance to check?

[@RadioSnivins]

Informative as always. Another thing I've found is that some cassettes have protruding pins that hold the low gears together, so there's not a flush surface on the lowest gear, and it breaks plastic spacers.

[@LvcianoN]

I have used a file on those plastic spacers to make a notch in order to clear the spacers, no problems.

[@RadioSnivins]

Yer, me too ... after having cracked one. They're brittle fellows. They've got a smidge of bend, but not much, and they disintegrate. Safe rolling.

[@CKBrew]

RJ!! As per usual, you're the MAN! A follow up question: As the selection seems to be vastly greater for 8 speed cassettes, in worst case, can you just buy an 8 speed cassette and throw out one of the cogwheels and fit on to your 7 speed hub??

[@zmurray9499]

The only simple explanation on KZbin👍🏼

[@jmjavs5740]

Thank you for this explanation really clear and helpful. I bought a 2nd hand mtb, with 7spd cassette, after I checked your video I go right away and checked mine and found no spacer. But then few months later, I found out that this model originally had 8spd. Not sure if there are other parts changed aside from the freehub and cassette.

[@PedroElena1000]

Very good explanation , congratulations from Spain!

[@carolynbrown3076]

I'd like to upgrade from 6 now I'm ancient and find mountains a bit tough. I'd like a 1-1. My bike was built for me when I used to race in 1988, and I love the 531c frame for touring which is all I do now. It used to be impossible to fit a 7 speed, but I guess chains have become narrower -- could I possibly fit a 7 speed (or more?). I cannot find a bike shop who even know what I am talking about! I used to be fairly competent at maintenance. This is the best advice I've found so far!

[@mtbboy1993]

Info about 11 speed: In case any one want to upgrade to 11 speed cassette, on standard 10 speed cassette it's possible,but you will get chain drop when back pedalling,because of the position of the cassette, a 11 speed compatible freehub/wider freehub,will fix this issue. the further from the centre/closer to the frame.I got Hope Pro 4,it sue a spacer for 10& 11 speed cassettes.

[@RJTheBikeGuy]

11 speed is a slightly wider freehub than the 8/9/10 speed freehub. So you are unlikely to find a bike with a 7 speed cassette that will take an 11 speed cassette.

[@mtbboy1993]

I did this with XT M8000 cassette. On a formula/bontrager hub with 10speed freehub.

[@mtbboy1993]

Of course,I knew that.

[@Shalmaneser1]

It's almost enough to make me buy an entirely new hub and restring!

Came across this vid the second time because now I know the answer to converting a 7 speed to 1x7. You don’t have to upgrade to 8 speed. Take the 11-42T 8spd cassette and swap your old 12T gear ring into it, making a 1x7 compatible setup. Hope I didn’t confuse anyone.

[@knightsljx]

this video is a god-send. you would think this information would be widely available on every cycling website or video. But noooooo.... everyone just says the 7 speed hub is different from the 8/9/10 speed hub. Thanks, what am I supposed to do with that lack-of-information?

[@ns671fr]

As long as you have a modern standard freehub you can go up to a non xd 12 speed. Idk if in shimano its only up to 11 speed might be due to the way sram designed their cassettes. Love to hear your thoughts if shimano 12 speed cassette can fit. There's extra tricks to file down that elevated notch to give you more room on the hub.

[@kevinportilla9320]

Shimano 12 speed needs microspline, but You can use a sunrace 11-51

Hi RJ, I have a 7 speed hub without the spacer (30mm). When I fitted a 10 speed cassette and removed the smallest (11T) cog, it will fit in the shorter hub. The lock ring is still pressing against the new smallest (now 12T) cog. Question: will this set up work? What shifter do I need, 9 speed or 10 speed?

[@ricardodelrey7677]

I have a vintage SHIMANO FH-HG50 on vintage aero clincher rim rear wheel that only takes 7 speed cassette. I found out that buying a 8-speed-freehub and longer rear axle is cheaper than buying a new rear wheel so is it possible to replace the axles and free-hubs to upgrade? thanks : )

Quick question - do you keep the same rear derailleur and shifters after changing to more cogs? I wanna do this update to my road bike from 6 speed to 8 speed. Thank you.

[@DavidR8]

Thanks for this. Can a 7 spd (30mm) freehub body be replaced by a 10 spd+ (35mm) freehub body?

[@jsmithepa]

Remember, upping the number of cogs is just one thing, will you need new shifters, new derailleurs, heck I still have 90's down tube shifters so I'd probably have to buy new brakes/shifters too, and that sounds like a whole new group set! Staying with 7 for now.

[@RJTheBikeGuy]

The shifters need to match the cogs. The derailleur just needs to be compatible (SIS) and reach the cogs. So a 9 speed derailleur might work with 7, 8 or 10 speed also.

[@georgeb.wolffsohn30]

RJ The Bike Guy that's why I love my Simplex Retrofriction Levers ! ! ditch the index stuff ! !

[@georgeb.wolffsohn30]

oh, and to eliminate over shifting, get a Simplex "demultiplicateur". you can make finer adjustments more easily.

[@RJTheBikeGuy]

Don't get me wrong, having indexed shifting with more gears is nice. But the difference between 10 and 11 cogs is negligible unless you are a high level cyclist needing to get into very specific rpm/power ranges. 7 or 8 cogs are probably enough for most people.

[@johnjerizlopezignacio3891]

Thanks, one more question. Can I upgrade from 7 speed road bike to an 11 speed wheelset? (Planing to buy a groupset.)

[@RJTheBikeGuy]

The hub will be wider. From 126mm, to 130mm (or a hair wider). A steel frame can be spread, otherwise, no.

[@marcushurst6757]

Can you just change the wheel out for one that has more chain rings? And would you have to change the chain to a longer one? Or could you use the same one?

[@magpie7791]

@RJ the bike guy if you can't put a 10 s cassette on 126mm rear freewheel? can you just buy a 130mm with a free hub to fit a 10 speed? would that work

Hi RJ, my 90s steel bike has a 7 sp cassette wheel that need to be replaced as cracked. Can I fit 8 speed wheel on the bike and use 7 speed only as not to replace downtube shifters?

I have a question. Is there a limitation for installing the wheel with upgraded 11 speed or 9speed cassette to the frame that only has 7speed originally?

[@RJTheBikeGuy]

Yes. The hubs are wider. So the frame spacing might be a limit. If it's a steel frame you might be able to cold set it wider. kzbin.info/www/bejne/j5XMk6Cud9qAr5I Don't do that to a non-steel frame (aluminum, carbon, titanium, etc). For those you might be able to squeeze the wheel in, but that can be a hassle, and or other issues .

Another 'hack' for 7 speed freehubs: you can install 8 9speed cogs on a 7sp freehub body. In order to do this you have to get rid of the rivets of the cassette and then pull one cog of. Do this with a 9sp chain, crankset and shifter where you lock one step.

The wheel doesn't care how many teeth the cassette has. Either it fits or doesn't. Maybe he meant the your derailleur can't handle a 46 tooth cassette. That has nothing to do with the wheel.

Now, onto my next change & question. My bike is a 1991 Trek 1200 which I love. It is a seven speed with the original shifters & I want to know about going to 8 cogs. Can the original index shifters be adjusted to 8 speeds? I just saw this video & haven’t yet done the measurements but I thought I would first ask about the shifters. I’ve already changed the chain, chainrings & have built my own cassette out of the original cassette & another one I bought on Amazon. Thanks RJ & please keep the videos coming!

The frame is spaced for 126mm for the rear wheel. An 8 speed rear wheel is spaced to 130mm. You can maybe squeeze the wheel in. Don't try cold setting the frame though.

RJ The Bike Guy Thanks for that, but what about the shifters? I just removed my front detailed & im going 1x now. I live in Florida, so there was no dilemma in making the change. Anyway, I don’t need the shifter for the chainring & wonder if I could use that in conjunction with an 8 speed cassette, if I make that change.

Thanks for the info... what happens to your shifter? If I have a 7-speed shifter, can I remove 2 of the gears (and place them in the back as spacers) and still use my 7-speed gear?

On 7 speed hyperglide Shimano freehub you can "easy" add 8 or 9 cassette, but jsou must separate and use 8 from 9speed cassette or 9 from 10speed cassette with her narrower spacers!! Than use 9/10 chain. This is useable on road bicycle.

Yes that is good but i learn that by changing the hub you can still use the same rim and at lower cost can be upgraded to higher than 7 speed. 😊 also you need a new chain, because the thickness and may need a new crankset or change the rings on it, some 7 speed crankset may work but the way they build the bikes today is to make you buy everything. I know all of these because I'm going through this process myself. 😅😅. Also you need a longer axel and may need to wide the back of the frame. I think i cover everything.

I have novatec hub and it says for 8,9,10 speed cassette. But i want to upgrade my drivetrain into 11speed. Do you think my stock hub can accomodate 11speed??

Hi RJ, and thank u for the new video. I've just a question concerning rear hubs: I currently use a wheelset with shimano ultegra 6500 hubs (wich are part of my 6500 9 speed groupset). Do you think I 'll have enough room to put on them a 10 speed cassette on the rear hub and upgrade to 6700? Thanks

You should have no problem.

I have an 3*8 system on my bike and I want to change it to a 1*10. Do I have to replace the hub or can I just by a 10 speed cassette?
