    10 speed compatibility

    Will a 10 speed cassette fit on a wheel that came with 8 speed?

    If it's Shimano or SRAM, you'll also require a 1mm spacer before installing the cassette.
    I'm ignorant of Campy.

    Yes. The cassette should come with a spacer.

    I have buy one road bike. Is had cassete 7 speeds I replace with cassete 9 speeds. From 3 different cassetes i do one. Is skip in 3 cogs in high gears when i shift is skip is can happens because the spacers is wrong sizes. And one other cassete i try is not turn freely that is can do damage in the wheel?

    What type of shifters do you have ? If you have 7 speed indexed "click" shifters, then they do not know you added 2 more gears.

    My bike have downtube shifters. Is index and friction too. When i turn in index is shift but not in all gears i know that do because is not made for 9 speeds cassete. Now in friction side is shift in all gears i use one broken trainer as stand i work on the bike, Is shift okay but when i take the bike for ride that time is skip in the 3 high cogs. 15-14-13

    why would a 10-speed cassette need a spacer on a freehub body designed for 8 speeds? i thought an 8-speed freehub cluster carrier is narrower than a 10 speed. and i thought the cassette was too. maybe i've got this all wrong, but i thought that with just about every additional cog, from 5 on up, hub designers were cheating on the drive side, necessitating more dish, which should mean that as time went on hubs, designed for fewer cogs, became obsolete as more cogs were added.

    if the OP asked whether an 7-8 speed hyperglide cassette would fit on a 9 or 10 or even 11 speed hub, i could understand that an additional spacer might used before or after the cassette was mounted.

    Do you have a 9 speed chain to match the 9 speed cassette ?

    There's a lot that you don't know, but you keep on posting......
    As the number of cogs increases the thickness of the cogs & spacers decrease. The largest cog on a 10 speed is also built differently.

    you might want to look more closely at the links you posted, specifically the "total width" column... under the title "cassette and freewheel spacing".

    Shimano 8-speed freehub bodies accept 8,9 and 10-speed cassettes since with each increase in cog count, the cogs and spacers got narrower so the overall width remained constant. The largest cog on a 10-speed cassette is recessed slightly so the 1mm spacer supplied with these cassettes is needed on 8/9/10-speed freehubs but not an the relatively rare 10-speed only Shimano bodies. A 7-speed cassette can be used on an 8/9/10-speed body but requires a 4.5 mm spacer to fill the extra width.

    Also, as the cog count increased the rear dropout spacing was also increased from 120 mm (5 and ultra-6 speed) to 126 (7-speed) to 130 (8/9/10-speed) so the increase in dish was minimized.

    Why do you think I posted them.
    IF you look at 7 speed vs 8 & 9 speed you see a noticeable difference.
    The difference between 8 & 9 is quite small, being 1.1mm. 10 speed is .7mm wider then 9, but has the overhanging cog that actually results in a narrower stack (lock ring wise) then the 9.

    Look at the 2nd link grasshopper-

    the width sheet starts with a 5 cog (freewheel/cassette) at 24.0mm and ends with an 11 cog (campy) at 40.0mm. so 24 is shorter than 40, isn't it? which was the point of my post. the OP did not specify any brand name.

    BTW, the second link goes to the same webpage as the first.

    Your question was why do you need a spacer for 10 speed.
    The 2nd link goes to the same page, but to a different section describing overhang for the 10 speed.
