story; i got my first mtb last year. i got a GT avalanche 27.5 [i started with an ozark trail] buddy gave me a rockshox recon fork. fast forward to now, i purchased a thru axle wheel, i did not know hubs where different sizes. so my fork is 15x110mm and the hub in the wheel i got is 15x100mm.

am i fucked? do i have to return the wheel and shop for another brand? [i matched what was on my bike which is WTB]. so i get a new hub and have a shop put it on and true the wheel? or can i get 2 5mm spacers for each side?

thanks. im still learning.

Comparing a 27.5 and 29 fork, assuming that they have exactly the same travel amount:

The axle-to-crown (leg length) is slightly longer on a 29 fork. The axle offset is slightly shorter on a 29 fork. The steerer tube is thicker walled (internally) on a 29 fork. The arch/brace height is higher on a 29 fork.

The first two are subtle changes to the steering geometry. Putting a 27 wheel on a 29 fork will give slightly slow / floppy steering. It will still work.
