basher Posted August 2, 2008 Report Share Posted August 2, 2008 about 40/50grams is saved per tyre. Adam @ tarts believe that it improves grip when on the edge of a object. Im guessing the idea behind it is that the knobble are able to move and be more supple so can grip better. Quote Link to comment Share on other sites More sharing options...
Muel Posted August 2, 2008 Report Share Posted August 2, 2008 I cut the side knobbles on my rear creepy crawler, and the little diagonal ones on my front Try-All. Saved 130g in total, and they both definately grip the edges of things better.How much weight you save depends on the knobbles you cut, if you cut any of the middle section blocks on the rear tyre, you'll save about 50g. If you cut the larger ones on the sides, you'll save around 100g. I weighed the tyre before and after, and that's what I saved.Works brilliantly, but I reckon that wear life with be shorter, and they look really wierd.

Oli Smith Posted August 2, 2008 Report Share Posted August 2, 2008 (edited) Personally I think that trying to save weight is sad. Pro's do it. But just ride your bike as it is. I mean cutting knobbles of your tyres thats just silly. 100g lol. I don't give 2 shits about grams.

I mean cutting knobbles of your tyres thats just silly. 100g lol. I don't give 2 shits about grams.I agree somewhere along the way with that, I think that making your bike too weak to save weight is a bit silly, and I'm a fairly shite rider, but I'm good enough to be able to feel the difference between a light bike and a heavy one. Light bikes are less tiring to ride, you can make it to the end of the section without being completely knackered with a lighter bike. Could you not just have weighed the Knobbles after you cut them?Who said I didn't. Quote Link to comment Share on other sites More sharing options...
stunt man t Posted August 2, 2008 Author Report Share Posted August 2, 2008 Could you not just have weighed the Knobbles after you cut them?right, done it!just cut the nobs off the outer tread,and weighed the bits i cut off,using my mums kitchen scales and they weigh 2oz :$ thats like 52g, isnt it?

Captain Scarlet Posted August 2, 2008 Report Share Posted August 2, 2008 I'm all for thinking they give better grip.When you cut every other outer tread off, the remaining ones stand proud from what is now a bald area of tyre so in that tread is like a hook whereas if there was a tread occupying the empty space it would not have the same hook effect.I guess the best way to think of it would be a pedal with lots of pins in it, if you have lots of pins the surface area would be greater (which should therefore mean more friction and therefore grip), but if this was the case we would be seeing completely flat pedals with no pins at all, in which we all know a pedal with pins (back to the hooking idea) has better grip than pedals with missing pins.Its probably one of the best minor weight saving techniques about, tyre wear is amazingly different, and it doesn't make your bike any weaker, it probably saves about the same weight as drilled sidewalls (but again without the weaknesses).

Henrik Y Posted August 3, 2008 Report Share Posted August 3, 2008 Overall it may not affect the grip much but in some situations it may do a lot.But I don't think you'll ride better because the bike is 500gr lighter. Quote Link to comment Share on other sites More sharing options...

You cut every other one off yea? Not every single one? Quote Link to comment Share on other sites More sharing options...
manuel Posted August 3, 2008 Report Share Posted August 3, 2008 50 grams is not much - however 50 grams on a tyre (rotational weight) counts for more ... so yes it is worth it - as pretty much everyone says - grip is not sacrificed. Quote Link to comment Share on other sites More sharing options...
tmks88 Posted August 3, 2008 Report Share Posted August 3, 2008 26" tryall on rear26" maxxis holy roller on frontsaved 120g from cutting both tyres, i cut only half of the side ones on the rear tyre, and some from the center of the front tyre Quote Link to comment Share on other sites More sharing options...
Henrik Y Posted August 3, 2008 Report Share Posted August 3, 2008 (edited) Why waste the time and tyre to save a few grams?Go for this one at once instead: 26 x 2.35 620gr Edited August 3, 2008 by Henrik Y Quote Link to comment Share on other sites More sharing options...
Swize Posted August 3, 2008 Report Share Posted August 3, 2008 IMO it would be more useful to have a shit before you go out that to do it. Quote Link to comment Share on other sites More sharing options...
16 years later Posted August 3, 2008 Report Share Posted August 3, 2008 Why waste the time and tyre to save a few grams?Go for this one at once instead: 26 x 2.35 620gror get a onza porcupine for £10 it's only 560g with all it's knobs.Then cut em off be probs like 450g if not less Quote Link to comment Share on other sites More sharing options...
Al_Fel Posted August 3, 2008 Report Share Posted August 3, 2008 IMO it would be more useful to have a shit before you go out that to do it.Sweet so I weigh 100lbs and my bike weighs 50lbs I'd be better off than someone who weighs 200lbs with a 20lbs bike. I see where you are coming from there. Quote Link to comment Share on other sites More sharing options...
basher Posted August 3, 2008 Report Share Posted August 3, 2008 IMO it would be more useful to have a shit before you go out that to do it.Theres always someone whos says this. You dont through shits around up walls do you. It will do f**k all difference having a shit as the bike is no lighter. In a comp a lighter bike will help from tireing because your throughing a lighter bike around. How on earth will having a shit do that. Just thought id say.

I see where you are coming from there.100lbs, you are one light dude!I went on a ride today where about half the riders have cut knobbles off. It has been proven to be cool because Bigman has done it. Quote Link to comment Share on other sites More sharing options...

How on earth will having a shit do that. Just thought id say.The point i was making was your saving like 100g 200g at most. Its useless. it wont make a difference at all. I dont think you would even notice a difference on the bike. Ok it all adds up in the end but pft leave them as they are. If your riding comps with the potential of wet muddy rocks would you wanna be cutting tread off? Your not gonna go out and gap 3" more because you have 200g less. 200g would also make sweet FA to your stamina. Quote Link to comment Share on other sites More sharing options...
Muel Posted August 3, 2008 Report Share Posted August 3, 2008 (edited) Trust me, you can feel a 250g difference when your bikes 8.8kg to start with. It all adds up anyway, If you get 2 bikes next to each other, where one is 10kg and the other is 8.5/9kg, the difference is massive. I know because I did it.I was in between bikes at the time, but still, the difference was massive.EDIT: The one nearest had my 06 short frame on there, once I got my 08 Long I built it up with my 07 long to compare, the geo was almost identical between the 08 and the 07.
