I would also like to do the same as I was discussing with @[B]TomH79[/B] yesterday the Expert comes with a DT Swiss hub but its unclear what would be compatible with the Specialized branded hub on the Comp / Comp Carbon. Hopefully its also DT Swiss compatible but it's unclear.
"Specialized Turbo, sealed cartridge bearings, 12x148mm thru-axle, 28h”"
Expert has a ratchet hub?
Would be a easy job to find it.
