fork

[byrt]

Hi Everyone
Im very new to building my dream bike. Im buying slowing all the components.

How do you choose the right fork?? where do I start?? I was looking at the chainreaction site and there pages and pages!!!
I have selected 29", rockshock and I get a few that I can select.

Do I buy what I can afford?? 9mm or 15mm
I was looking at this one http://www.chainreactioncycles.com/au/en/rockshox-xc-32-tk-solo-air-forks-9mmqr-2015/rp-prod109687

Can anyone point me in the right direction please??
Thanks

Unless you have already the wheels you like. You should go with a 15mm thru axle.
And beware the chainreaction's page you linked to, seems to have just the 26" in stock.

You can check http://www.bike-discount.de and http://www.bike24.com too, they have better prices in general.
