For USA and Canada the envelo crew have a limited number of 26" Durolux that can be set at 140-180 mm. That fork is no longer in production so get em while you can. Its a mix of straight and tapered steer as well. Best to call or email to see what's left. email@example.com or 608-229-6612. For those in Europe the office Germany may have some left as well check with them at firstname.lastname@example.org
Another alternative is to run the 27.5 Auron / Aion and reduce the travel a bit to keep the axle to crown in close range, not ideal but an alternative.
