15mm or 20mm wheels?

[BBN]

What is the benefit/difference between 15mm and 20mm wheels?

 

What is the benefit/difference between 6 bolt and center lock wheels?

[Plentipotential]

By 15/20 mm are you refering to the thru axle on the front wheel?

[BBN]

Probably, thought it may have been the rim width but makes sense, 20x100mm through axle? Is this better?

 

Just to note, I'm asking about mTB wheels.

 

Also wondered what a MTB clincher wheel is?

If you go through axle you will need a specific fork to go with it. Allot of trail bike are 15mm and the heavier AM and DH bikes use 20mm.

 

 

 

Re the rotors, there is not benefit between the two. The 6-bolt discs are lighter then centre-lock but I guess the saving on the discs moves to the hub that needs more meat. You can run a 6-bolt disc on a centre-lock hub if you use a special adapter but not the other way around.

Both standards have their selling points, although IMO 15mm is wasted. The new Maxle Lite system from RS is as light at the 15mm QR and considderably stffer due to its 110mm spacing as compated to teh 100mm spacing of the 15mm system. As Mumpara mentioned though you will need the corresponding hub to match the fork and visa versa so be careful!

 

As for MTB clincher, its a regular tyre. Tubby [Tubular- glued on tyre ala road] is the alternative

....although IMO 15mm is wasted...

 

I have heard this from quite a few guys in the know. Go big or go home - through axle will give you a lot less flex in the fork and make for a smoother trail ride.

 

I read somewhere that the fork flexes up to 6" before it breaks! Not that I have heard of anybody actually breaking a fork due to flex, but still, 6" is quite a bit.

 

If you are not sure, flex is the movement of the fork that is similar to the yellow-pages animated symbol of some time ago? If you would use your middel and first finger to 'walk' - that is the flex spoken about - hope that makes sense?
