How to install dynamo hub into mtb I have a roval carbon wheel on specialized epic hard tail.
I want to install son dynamo hub on it.
I've seen it done on https://bikepacking.com/plan/lael-wilcox-2019-tour-divide-gear-list/
(SON 15mm thru-axle hub / Roval carbon rim)
Although I don't know the exact model of the hub or rim.
Is there a right size hub for wheels?
Searching for son 15mm thru-axle gives me two versions SON 28 15 and SON 28 15 110.
Can I go with any of these two?
After installing hub, how do you put the wheel back?
Do you replace spokes with the right size and tighten it?
First you need to buy a hub which fits the axle type and dropout spacing of your bike. If you don't want to buy a new rim, you also need to buy a hub with the same number of spokes as your rim.
Once you have the hub, you need to measure the diameter of the spoke hole circles, and the flange spacings. You can try to get these dimensions from the hub documentation, but I always measure to be sure. You should be very skeptical of hub dimensions from unofficial sources or from online spoke length calculators. They are often wrong. You also need to know the &quot;ERD&quot; of your rim. You can measure or look it up.
Once you have the dimensions, you need to calculate what spoke length you need. You can use an online spoke length calculator, or use several and compare the results. You can buy custom spokes from many bike stores or on eBay.
Now with your new hub and spokes, you can disassemble the old wheel and build the new wheel, or you can have a bike shop do it.
