Spez Ground Control / Fast Track for Sani?

[KevinHow]

If you have no choice but to use Spez tyres then put the GC on the front and the FT on the back. I believe that Sani is like riding on a Billiard table - so you should not tear the sidewalls??

[davetapson]

Got GC 2.3 and FT 2.2. Fatter than I'd have chosen but there are many comments that these tyres are narrower than expected so hopefully will balance out.

New research is suggesting that fatter rolls faster. ;-)

Rider or tyres?

I am using GC 2.3 front and FT Control 2.2 Rear for Sani after ripping my GC 2.1 rear sidewall while bundu-bashing/bushwhacking in NW Province...

 

One thing that I have noted is that the Specialised tyres are VERY sensitive to pressure, so do NOT over-inflate. I find that if I pump them up too hard (i.e. 2bar), the handling suffers (I weigh 80kilos).

 

Hope that helps and GOOD LUCK.

 

 

PS: you may struggle to find FT in 2.1 - they were in short supply in Jhb.

This also I told myself. Will let you know coming out of the umko valley.

 

Will also run them soft 1.8 and 2.0.

 

Edit:

 

Maybe even 1.5 / 1.8. Problem is that my pump (I think) under-reads, so 1.5 on my pump is probably 1.8.

 

Means that I'll need to pump to 1.2 / 1.5

Play around with the pressure on the spez tyres. They definitely have a sweet spot for each rider weight...

I run Ground Control 2.3 front and back. They were definitely a bit all over the place until I hit the pressure sweet spot. I am 73kg and found front 1.5 bar and rear 1.8 bar gives awesome grip in the corners. I have nothing but respect for these tires. I have put them through a lot.

Well, I fitted them on over Joe's and Stan's strips (had only one of each) and they went on like a dream. Pumped them up with no sealant in and using a floor pump. Held full pressure for the full day and I've now just bunged some sealant in. One thing I've learned is that if you can't inflate tyres without sealant in, you can't inflate them with sealant in, and you save a hell of a mess.

 

I've pumped them to 1.3 and 1.6 by my pump which I think is probably 1.5 / 1.8.

 

Definitely handle differently to the Maxxis combo - somehow you 'roll' into the corner now - probably due to the bigger radius of the tyre? My bike looks like a fat bike, but seems to roll just fine. Definitely better than the 2.35 Kenda Nevegal that the bike originally came with.

 

Can't wait to use them in anger.

Got a set of 2.1 GCs in Feb, at that time I could not find better value tubeless ready tires for my 26er and so far very impressed with them (almost 750km done, including some muddy and dry/loose races). Hoping to get at least 2000km out of these (previous sets of tires did not reach 2000km, probably because I do a lot of tar as well).

 

Currently running them at about 2bar each (94kg), very grippy compared to my previous sets of tires.

My front onza Canis is now on about 5000! and this will be it's third sani!... Outer tread is still fine.. Middle is a bit worn... but i am leaving it on... did karkloof in the wet today and it still grips like anything

[davetapson]

Running 1.2 / 1.5 (by my pump) Just awesome. So happy. Cornering is better, softer is more comfortable...

Can recommend.
