How long is an 11 speed freehub?
How long is an 11 speed freehub?
Without spacers, the freehub is just shy of 37mm (no accurate calipers on hand).
How wide is an 11 speed hub?
Total Hub Width only grows by 1mm. This puts the hub at 131mm wide, which will fit into a standard 130mm spaced road frame with no problem and likely cause no alignment issues.
Are 10 and 11 speed hubs the same?
The Shimano (and SRAM) 11-speed freehub is wider than the 10-speed one, because the 11-speed Shimano (and SRAM) cogset stack height is taller than 10-speed.
Do I need a spacer for 11 speed cassette?
If you have a ‘road’ 11s length freehub body then you do indeed need to use a spacer to fit CS-HG800-11 to it. CS-HG700-11 is the same length too, again available in 11-34. Both CS-HG800-11 and CS-HG700-11 are supplied with the required 1.85mm spacer so they can be fitted to 11s road freehubs.
Do I need a new hub for 11 speed?
Shimano/SRAM 11 speed cassettes are wider than 8/9/10 speed ones. So yes, you need a new, wider freehub body, unless your old one was not very old and used a spacer to fit a 10-speed cassette.
Can I put an 11 speed cassette on a 9-speed hub road bike?
An 11-speed cassette will fit on a 9-speed hub only when the hub is wide enough. Luckily, 8,9,10 and 11-speed mountain bike hubs have the same spacing, and one can therefore use an 11-speed cassette on all of them.
Can I put a 11 speed cassette on a 12 speed hub?
The 12-speed cassette is designed to be backwards compatible with the existing 11-speed road freehub, while the 12 speed-specific freehub (available on Dura Ace hubs currently) can’t be used with the 11-speed parts. Sram HG-style cassettes are largely the same spacing as Shimano, with the 10 speed exception.
Are 11 and 12 speed hub the same?
When should I use freehub spacer?
You don’t need the spacer. You are correct, it is intended for when you are using a narrower cassette. If you can torque the lock ring without the spacer it shouldn’t be used.
