Do Specialized allow you to fit 180mm triple clamp forks to your 2026 Levo S-Works.
Short answer: no. The 180mm figure everyone quotes for Gen 4 Levo is Specialized's ceiling for single-crown forks - the Levo Gen 4 frame is rated for 180mm fork maximum, per what
@Rando_12345 dug up, and that's echoed by the stock spec, which pairs the platform with a single-crown ZEB rather than anything with a second crown bolted on.
Triple clamp is a different animal - different steerer length, different headtube/legs geometry, different loads through the head tube. Specialized's own dual-crown blessing lives on the Kenevo line, not Levo:
Kenevo models are warranted for use with dual crown forks, which was the case as of 2020 - worth double-checking that's still current, but the point stands that it's a Kenevo allowance, not a Levo one. There's no equivalent sign-off for the Levo/Levo 4 chassis that I can point to.
Practically: even ignoring warranty, a 2026 S-Works Levo running S-Works-spec electronics and a fairly road-bike-steep 63.6 - 63.7° head angle at stock 180/170 wasn't drawn around a DC fork's extra weight and stack - you'd be fighting geometry as well as Specialized's paperwork. You're already at the sanctioned ceiling with your 170mm Zeb; if you want more front-end plush and a slacker head angle, that's a "buy a Kenevo" conversation, not a "bolt a Boxxer to the Levo" one.
