Slime

[Threevok]

Is it possible to more slime in not a easy job Halfords charge six pounds and garantee for two years any small punctures repair for free.

Just buy slime tubes and replace when you (rarely) hit punctures so big that they wont seal.

Save your money for maintaining that "swept back" hairstyle you seem to have developed

Correct. I've heard the ideal ratio slime to air is approximately 9/1

How exactly do you measure that?

You have lost me.

I've found the more slime you add, the less air you lose, when you get a puncture

Are you sure apart from the fact 250g is only a 1/4 of a Kg, does an empty innertube weigh 250g?

Slime tubes are quite heavy.
I usually put about 50-60 gr of sealant in each wheel.

So yes it's a consideration when making your XC bike super light.
Add to that lightweight tyres and you soon lose a kilo +.
Doesn't make a huge difference in many ways but try buying a kilo less in cycle parts.. very expensive reducing weight lbs per£

As per @Drago a FB like me doesn't care about an extra kilo, but i still don't think 2x slime tubes weigh anywhere near 1Kg

If anyone wants to know, I have two inner tubes currently in my bag, one Slime Smart tube and one normal Lifeline tube.

Both are MTB 26" x 1.75 - 2.25 - Schrader with valve caps on.

I have just weighed them

Slime Smart 325 grams
Lifeline 220 grams

That's a 210 gram increase (both tyres) in using slime tubes over normal ones

It's approximate I reckon at least a couple of litres of slime per tyre

Somewhat less than I flush down the U bend each morning.

I find it a bit of a juggling act really

If I use lighter tyres, I use slime tubes.
If I am using heavier puncture proof tyres I use lighter tubes.

It all balances out

Might try the Swable big Apple tyre in the rear has any one got experience of them.

I'm onto my second pair of Big Apples on my 20" wheel bike.

Fairly robust trekking tyre, but not as puncture resistance as a Marathon Plus.

It's a balloon tyre, so you will need plenty of frame/mudguard clearance.

No. It will just add to the weight of the tube. If it was me I’d be using Stan’s Race sealant. It’s absolutely superb stuff, and seals better than slime. It has to be the ‘race’ variety, not the cheaper version, as the race version has twice the concentration of sealant crystals in it.
It’s this one.

I use it in my inner tubes, and it’s saved my bacon a fair few times, although ( ironically ) not when used in tubeless tyres ( which is what it’s meant for) mainly due to copping too many side wall slices, on the tubeless tyres ( which is their Achilles heel ).

Yes I've been riding on a pair for years. Very puncture resistant... but my anecdote about riding 15 miles home with big thorn in my tyre was through a Big Apple, so they're not infallible.

No I suppose not.
