Specialized Ground Control

Balanced all-around tire for mixed XC or trail conditions.

Why I like it

The Ground Control hits a sweet spot for riders who want an aggressive, capable tire without totally giving up speed. I ran one in the rear at Breck Epic, where the mixed terrain and gnarly descents really tested everything — it rolled well, gripped hard, and felt secure on wet, loose, and rocky days.

Quick Specs

29 x 2.35” size (GRID casing, T7 compound recommended)

Great durability with puncture protection
Confident grip on loose and wet surfaces

In My Setup

I’ve primarily run it as a rear tire.
At Chequamegon, I ran Ground Control front and rear — it gave me the confidence to stay on the bike during loose climbs like Firetower when others were walking.
The GRID casing has been super reliable for me — I raced Breck Epic with it and didn’t suffer a single flat.
Rolls a bit slower than something ultra-slick like an Aspen ST, but the grip makes it worthwhile for tricky or mixed terrain.
If you’re racing on a course that’s mostly fast but has some rough sections, I’d consider this against something like a Rekon Race if mixed conditions are anticipated.

Notes

I’ve run it without tire inserts and had great success.
Orange Seal endurance sealant is always a good call.
It’s a great tire for riders who want a little more aggression and grip without completely sacrificing rolling speed.
On pavement or super smooth hardpack, it won’t feel as fast as pure race-focused XC tires — but for anything remotely gnarly, it’s awesome.
