An upgrade that can help your mtb riding!
I had a fellow mountain biker email me a great question the other day.
“I do have one question. I’m wondering what your opinion is on the importance of a really good rear hub. I tried to find something on the web page but I couldn’t. Personally I find that a quality rear hub is one of the best improvements you can make on a Mtn bike. It might be because I ride trials but I fell there is a huge difference between instant engagement and near instant engagement, weather climbing or descending. I was just curious what your opinion might be. I don’t often get to ask questions of bike experts..
The answer is, yes in many situations.
When climbing a technical climb with lots of rocks and ledges the near instant engagement makes timing of pedal wheelies and weight shifts much easier and precise. These hubs eliminate the “dead spot” when you pedal 10-20 degrees with no engagement. This dead spot can cause your weight to move forward before your bike moves forward often shifting you out of position. Better engagement also allows you to keep your feet more level when ratchet pedaling, requiring less downward movement to achieve the same amount of forward progress.
Even while descending the quick engagement allows you to apply power to the pedals a hair quicker coming out of corners. This leads to a feeling of being more precise and in control.
Here is a list of some hubs with quicker engagement and number of points of engagement (I am skills coach not a bike part nerd, I am sure there are quite a few I am leaving out) XT 36pt., DT Swiss 36pt, Hadley 72pt, Chris King 72 pt, Industry 9 120pt, Halo Supa Drive 120pt. For me it feels like the Hadley and Chris King work great with 72 points of engagement which I believe is every 6 degrees and the Industry 9 and Halo are about every 3 degrees. There is also a newer company, Stealth Hubs that claim less than a degree of rotation for engagement but I haven’t heard much about them (which only means I can’t give you my opinion on them). Do your research and find the hubs you like and that fit your budget, some of these hubs cost almost as much as our three day skills progressions!
Personally I am a big fan of both Chris King and Hadley Hubs. I have a Hadley rear Hub on my practice wheel set and it has lasted six years so far. My race wheelset has Chris King hubs and they have lasted two seasons so far and still work great.
