Hi, So I have an old 20mm Pro2 hub currently laced to a 26" rim sat doing nothing.
I'm thinking of upgrading the front of my 29er from it's current QR set-up to bolt through forks by lacing the 29er rim to this hub.
As I understand it 20mm is 110mm wide. Does that mean if I changed the endcaps to 15mm I would need a boost fork or can I just get a normal non-boost fork?
Yes, if you have Boost/110mm hub you would need a Boost/110mm fork irrespective of the end caps
Pro2 is 100mm with QR or 15mm, and 110mm with 20mm end caps.
Change to 15mm end caps and use non-Boost fork, or get the Boost adaptor and run Boost forks.
If you fit 15mm end caps it’ll need a non-Boost fork as it’s not a Boost hub shell.
Unless Hope make Boost conversion end caps in which case you’d have both options.

They do
If you're gonna be doing a new wheel build for 29in boost, I'd start with a proper boost hub myself.
Front hubs are much of a muchness anyway.
What cha****ng said unless money is very tight. If you are determined to reuse the hub then Hope do a boost kit which requires a re dish. Since your rebuilding the wheel that's not an issue. Front hubs are cheap though so better to flog the wheel and just get a boost hub.
Thanks guys - Happy to have a non-boost fork so i'll get some standard 15mm caps
It’s not as easy as you might think to get new non boost forks, not at the shiny end anyway. Worth considering for the future.
