So, couple of options:

Front: brand new ST 2.5 High Roller
Rear: brand new ST 2.5 High Roller

Front: slightly-worn few-years-old (will the rubber still be good?) Comp 32
Rear: brand new ST 2.5 High Roller

Or should I think about buying one/two 2.7" 'rollers?

Course is essentially dry I think, and forecast is for breeze and sun over the weekend, so any residual dampness should dry up. No idea what the bottom woods will be like, but the race is won/lost on the open top section I'm sure.

I have no idea why you would consider anything bigger than 2.5 up there. Stick the HRs on and go - the last thing you want is some massive heavy tyre on either the first or last (especially the last!) sections

Because I'm scared of the rocks mark! And of the punctures, more to the point. Last year I was over 40psi before I stopped flatting! Apparently Cathro runs 50!!!

Always Minions for me. Doesn't matter whether it's wet or dry up there.

Last year size wise I ran a 2.5 front and 2.35 rear with no problems, I'm a slow arse senior tho!

 

[monkeyfcuker]

Seb what wheels are you running?

 

[- seb]

823s, I know ZTRs aren't built for the fort

 

[monkeyfcuker]

I'm gonna try my front one this year for ****s and giggles if it lasts Glencoe!

Anyway, have you tried a 721? They are more likely to dent a little bit and not puncture rather than pinch a tyre/tube like the 823's can.

 

[- seb]

I've not - I have 823s so I'll stick with them, not going to rebuild my wheels just to avoid a possible puncture. If I run the new 2.5s I'll set them up tubeless to minimise punctureness - the comp32 is probably tired enough that it would need a tube. Hope my sealant's still good, not used it for a while...

Seb, if you're spending your own money buy yourself a couple of DHFs - V much doubt you'll regret it. I agree with Mark n MonkeyFeck on size, and 40psi is about the minimum I ever run a rear tyre there too.

 

[- seb]

I bought some before but got 2.35s and never got around to trying them, and ended up passing them on to a friend who needed some tyres at a race that had none for sale. You reckon DHFs roll better than high rollers? I won't be able to get any at a decent price before the weekend anyway, so it's a moot point I think Next year!

 

[Gary]

You reckon DHFs roll better than high rollers?

Too hard for me to tell, every tyre I run rolls faster than my lightweight low tyre pressure running riding mates and I only ever use HRs as a rear tyre
I've never liked a high roller upfront, kinda weird coz I loved comp 16s

there is a noticable difference in rolling/acceleration speed by switching from a 2.5 to a 2.35 rear tho (partly down to the size/weight but also from having to run slightly higher pressures I'd imagine and probably more noticable for me since my local is the not exactly gnar, inners)

 

[norbar]

How the hell you manage to puncture anything with sealant? Imho the best option for no flats would be a thick tube + sealant + a good tire. In my days of puncture 3times a day it fixed all my problems for over 1.5 year.

 

[scottishmark]

tbh i rock higher pressures than normal at ft.bill and I only weigh 9.5st! (Monkeyf*cker aint much better, we've seen him getting blown clean off the track ) As gary says DHFs are the way forward, but HRs would be fine too
