- Spesh Ground Control / Purgatory
I use GCs on the back all year round. I wouldn’t say they were anywhere near ideal for slithery conditions, they’re more a hardpack tyre, but I prefer them to the Rons that preceded them on mud and slippery stuff.
A lot of people rate Butcher over Purg for a front tyre.Posted 4 years agosmatkins1Member
I must be in the minority thinking purgatory’s are terrible in the wet. A great fast rolling summer tyre, but I found it didn’t offer much cornering grip in anything put perfect dry conditions. I found the butcher a better all rounder in the Specalized line up of tyres.Posted 4 years agoTraceySubscriber
Only ever run Purgatory’s on the rears, have a combination of Butcher, Clutch and the old Enduro tyres on the fronts. Combination seams to work well for most of the time. Run them at 25 psi on all the bikes.
If they run the amnesty this year we will be stocking up again.Posted 4 years agobrassneckSubscriber
I was running a Storm Control on the back of my Superlight, it was ace for mud, but very draggy. Just switched to a ground control 2.1 on the rear, and a Purgatory 2.4 on the front. Seems to work well everywhere and is much faster.
Going to try this myself – the Storms are just a bit much .. the sort of track they come into their own I try and avoid through winter anyway. On everything else it’s like dragging a sack of coal around. If you’ve no choice though, they are a good cheap set of TLR mud tyres.Posted 4 years agodeanfbmMember
A purgatory is my winter rear, GC rest of year.
Find the braking grip of the purgatory to be immense in all conditions, trade off that it can feel a bit slow at times.
Cant complain about the GC, fast and consistent, compound can feel a bit plasticy on hard slick surfaces, or wet off camber with roots/rocks, but more than adequate 95% of the time.
Wouldn’t fancy either on the front too much, side knobs don’t look like they’d have the bite. Well that and a butcher on the front feels too good.Posted 4 years agomattongleyMember
There are much better options Front and Rear, have you looked at Maxxis?
I’ve tried both in 29 x 2.3, here’s my subjective view. The GC lacks braking traction and it’s lack of defined shoulder knobs means it lacks cornering grip and doesn’t signal that you’re reaching it’s limits; only suitable for hard-pack and rear wheel use.
The Purg has overly soft rubber which compromises braking traction as it gets a little squirmy under heavy braking especially on the front. The soft rubber also means it struggles to hold lines when cornering aggresively and again doesn’t signal your approaching the limits. Best on the rear, an improvement over the GC but not by much.
Compared to Maxxis/On-One/Geax both lack suppleness so again this compromises grip.
Hope this helps.Posted 4 years agosharkattackMember
This thread has become a perfect example of why I just fitted a decent set of tyres and stopped thinking about it.
I know I could get a front tyre that gives 18% better traction on a wet root at 45 degrees.
I know I could get a back tyre that has 13% more traction on a piece of Welsh slate.
But then of course, I’d be 6% slower in a straight line and I’d have to phone ahead to check the wind speed and enquire about the latest soil samples.
As it is I just chuck the bike in the van and go riding.Posted 4 years agoYakSubscriber
I run GC 2.3f/2.1r as a winter combo. No claggy mud here. Instead, more sandy mud, hardpack, roots and some rocks. The bigger 2.3 has a little more shoulder so the back goes first and when they drift they do in a nice controllable way. They are especially good in sand imo and rarely wash out. For me, and my local conditions – they are a chuck on and leave combo for the winter.Posted 4 years agonjciscaSubscriber
Ive been using butcher/purg combo and for most situations they have been good especially the butcher up front, also relatively light and go up tubeless easy with just a track pump. I have found they struggle on wet rock so could be an issue depending on where you ride. For me riding in the lakes this did become a problem.Posted 4 years ago
Now the cheeky bit… just bought some black chili contis so will be selling both the butcher, purg and a 2.1 ground control if anyone’s interested. All 26″ control versions.
