Tyre Recommendation For Taupo

Postby Hardster on Wed 24/Sep/14 9:48am

Hi there,

I am doing the round Taupo for the first time this year. I am wondering what type and size of tyre people would recommend?

I am looking at Gatorskins but am not sure whether to get the 23 or 25 mm. I weight 98kg. If anyone could help me out that would be great :)

I have tried a few searches but couldn't find anything.

Also may be interesting to understand how many tyres for Taupo.

25's, but not gatorskins. Get something nicer. I can Michelin Pro4 service course last year, but if you are partial to Conti, then why not a 25mm GP 4000?

I would always opt for 25mm tyres, especially for a powerfully built person of 98kg. The ride will be much less harsh and traction on the descents much better.

For why wider tyres are best read this for a start: http://janheine.wordpress.com/2014/01/01/tires-how-wide-is-too-wide/

25c gp4000s. Some of the chipseal is quite rough around the back and there's a rumble strip for much of the way up the lake. Lower pressures are good.
Whatever you go for make sure they are reasonably new and you can get them on and off easily.

Thanks guys :) - Think I will listen to that advice. Yeah I am a what I would say a strong 98kg, hoping to get down to 92sh for the ride.

Whats a "good price" for the Gp4000's? Also when you say reasonably new znomit, how many kms should i put on them before the race?

Thanks so much guys :)

111$ a pair at wiggle.
Put them on a week before and give the bike a tune then too, so all you need to do for race day is pump up the tyres and clean the chain.

I ran these very tyres last year. All good! I'm a bit lighter, but still enjoy the comfort of the 25mm. Run 85psi fr/90rr in the wet at 80kg. You'd want to add another 5 or 10psi, but I suggest you experiment yourself.

Price seems good. Also, there is no real diff between the original gp4000s and the v2 that I can find. In fact, my v2's have worse cuts in them, but YMMV.

I got 5000k out of a set of 23mm. I'd put a couple hundred k on a new set before the ride, but that is me.

Good luck, kick some ass

make sure you have a good look at the bike quarterly pdf and the tyre pressures - easy to get estimates a bit wrong if you're not careful . .

Can you fit a 28 rear? Conti do make GP4000S that size, and a single tube fits both 25 and 28.
I reckon a wider rear tyre makes my 83kg ass look smaller.

Do they?
The new model lists a 28c but nobody has stock. Yes I've been looking.

Wiggle will accept the order, ship the bits they have in stock, and ship the non-available parts when they become available. No extra cost.

Would a Roubaix Pro be fast enough for you?

Michelin Pro 4 alleged 25mm seems to measure 28mm on a modern 15mm rim.

I'm running a Specialised Roubaix Pro 25/28 rear. It fits my (steel) bike easily due to skinny sidewalls and rolls nicely, not very tough though.

28mm gp4000 would be amazing.
I always look to see if any are available, and there NEVER are. Presumably as they're like riding on a unicorn. While eating really nice ice cream.

28mm GP4000s arriving at the door of unbelievers is similar to the deal with Father Chrismas, and unlike that with ISIS.
(What if they start sharing information?) :o

I back ordered a pair of 25mm back when that was considered unusual, they only took a few weeks.
