What does Hg mean in hubs?
HG, short for ‘HyperGlide’, is the most common and traditional freehub body design available. Created by Shimano, it is the standard used for cassettes that have at least an 11-tooth cog as the smallest cog on the cassette.
How do I change my hope freehub?
You should be able to pull the freehub off by hand there’s a little spacer in between the freehub bearing and the hub shell bearing make sure that spacer stays against the hub shell bearing.
Are all Freehubs removable?
All moving parts are in the freehub body. Most rear hubs allow the freehub body to be removed. The body can then be flushed with solvent for cleaning, dried, lubricated with oil, and then reinstalled. Much of the process is similar to a hub overhaul.
What is a Shimano free hub?
The freehub is an extension of the right-hand side of the rear wheel’s hub. It contains a system that engages with the wheel when you’re pedalling, to propel you forward, and which disengages when you stop pedalling so that the wheel continues to turn without the gears and pedals turning.
Do you need boost spacing for 12 speed?
If you are running 12 speed, the clearances are so small between chain and cassette that you MUST run a boost spaced chainring with a boost spaced bike. If you don’t, the chain will “tick” on the next bigger cog when in the smallest 2-3 cogs on the cassette.
Can I fit a 12 speed cassette on a 11 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.
How can I make my hope hub louder?
Just ride it. They get louder the longer you ride them.
What bearings are in Hope hubs?

Why are some Freehubs loud?
Loudness in the freehub/freebody is usually due to the very light oil used to lubricate the inner parts. Thicker oil can be used to lessen the noise and even grease in some cases, but it’s high viscosity is pointed at for not being so efficient.
Which is better Pawls or ratchet?
Ratchet systems are generally spoken stronger, more reliable and need less maintenance compared to traditional pawl systems. Biggest reason for this is that the power transferred from the drivetrain to the wheel is spread of a larger surface. In general hubs that are “louder” usually have more engagement points.
How do I know if my free hub needs replacing?
Check the freehub for wear to see if it needs replacing or just cleaning and relubing. To do this, firmly grab the splined body and give it a wiggle. If it moves more than a couple of millimetres side to side, replace it. Otherwise, a good clean and oil will do fine.

Are boost hubs worth it?
Is it worth investing in a Boost-equipped bike? The short answer is yes. Boost width hubs help make wheels, forks and frames stiffer and stronger, and that translates into a much more predictable bike.
What is the difference between boost and non boost hubs?
What is Boost? Boost refers to front hubs which are 10mm wider and rear hubs which are 6mm wider than ‘standard. ‘ Boost front hubs use the same diameter 15mm front and 12mm rear axles. By making the hubs wider wheels can be built which are stiffer, and more clearance is available for 11 speed drivetrains.
Is a 12 speed cassette wider than 11 speed?
Since the 12-speed cassette has the same total width as the 11-speed, the space between cogs is narrower. This leads to “faster” shifting since the derailleur doesn’t need to move as far to switch gears.
Is more pawls better?
more pawls means, at least theoretically, a more solid engagement. increasing the number of pawls does not increase the number of points of engagement nor does it make the does it decrease the distance you have to ratchet back to find the next point of engagement.
What is the loudest road bike hub?
What Are the Loudest Bike Hubs? Some of the loudest bike hubs are, Hope hubs, industry Nine, Tune, DT Swiss, Hadley, White industries, etc.
What size are Hope bottom bracket bearings?
Size: 24mm (Inner Diameter) x 37mm (Outer Diameter) x 7mm (Depth) Seals: 2x Rubber Seals.
What is LLB bearing?
On most other bearings 2RS means that the seal is made from rubber and has one sealing lip rubbing on any flat part of the inner race. Enduro’s seals are usually either LLU (usually the MAX type bearings) or LLB (better for hubs).
Do hubs make your bike faster?
Because loud hubs have more engagement points and pawls, they engage faster which makes pedaling quick.
Which is louder ratchet or pawls?
Can I upgrade my freehub?
This is why it’s important to get a freehub that is compatible with your wheel. At FLO, Shimano/SRAM freehubs come standard, and you have the option to upgrade to Campy, XD, or XDR.
Should I grease freehub?
So a little grease on a steel freehub certainly can’t hurt when it comes to corrosion protection. Bottom line, not a big deal. If you do regular maintenance and pull the cassette now and then in the process, leaving the freehub body dry shouldn’t hurt a thing.
