Rigid fork with a larger tyre would be lighter and more reactive, just saying 🙂

Spinner Grind air otherwise.

Brood’s Eldorado is simply the best 20″ fork available ime.
Spawn Brood eldorado
Works just like a proper fork. Air with rebound adj and lockout. Genuinely plush with all 80mm of travel available.
MRP have the Rustler, but needs frequent rebuilds according to other dads with kids running this and the local shop that had a rental fleet of lil shredders.
Spinners Grind can be improved with dissassembly, cutting down the top out sprint to get an extra 10mm travel but its still a clunky fork with a simple air chamber, no air cartridge.
Money must be no object though as with anything small that works and has carbon lowersnull, its not cheap!
I’d be interested to see the Ride Alpha forks available.
