Default Stronger rubber cement?

Gentlemen,

Is there something stronger than the usual rubber
cement in
the patch kits? Ideally something that won't dry out
so fast
or where multiple cheap small tubes are available.

The reason is that I sometimes have larger holes from
side
wall blow-outs. Not inch-long gashes but one or two
tenths of
an inch long. The tubes I use are super thick and,
therefore,
expensive. $15-20 each and that's not something to be
thrown
out lightly. Instead of the li'l REMA patches I need
to use
thicker rubber from an older sacrified tube but this
has to
be vulcanized/cemented really well.

UK, but must be available all over

Go up to 180mmx95mm and are less than a UKP per patch.


Thanks! Time for a trip to the autoparts store since
there is

Looks like a Brazilian company.


The 30mm patches are 13 squids per 100! Surely, surely
even
Joerg can't get through that amount that fast!


I hardly get flats but when I do they are hardcore.
Typically
caused by those notorious #%&^!! flimsy side walls of
bicycle
tires. Which is also why I am always on the lookout for
tires
with better side walls. For the MTB I found that Asian
ones do
better in that domain but haven't found any yet for the
road
bike. Will try CST, their Conquistare tires look
promising but I
could not find reviews.

Heavier tires are generally better and finally those
appeared for
29". For 700c it's still slim pickens.

You do know that 29" ARE 700c, both using a bead seat
diameter of
622mm? It's just that one description is used for MTB and
the other
for road use.

I have been told that many times. But my CX bike feels
absolutely
NOTHING like the 29er did. On that the wheels felt massive
and heavy.
On the CX bike they are nothing of the sort.


Phil should try to mount a 29" Intense Trail Taker tire or
similar on a 700c road bike. Then it would quickly sink in
why this will never work :-)


Joerg, don't be ridiculous. Phil Lee was correct.


Tires formally labeled as 29" are simply not available in 25mm. At least
AFAICT.


A 559mm 26x2.3 tire will mount on the rim but can't possibly fit inside
the frame or fork of a Bridgestone CB1. So what? A perfectly common
700-35C touring tire won't clear in your road bike either.

That unsuitably wide tires exist for any given rim diameter in any given
frame doesn't make them different ISO sizes. There are a spectrum of
widths for almost every ISO format, choice is good!


Well, there aren't skinny 29" tires.


p.s. A 700-18 ultralight tire would fit your road bike rim as well. For
you, I'd suggest a wider tire.


Yes, I had very narrow tires before and found that 25mm is better for
where I now ride. 28mm would theoretically fit but only when the rear is
very well trued which does not hold for long on my routes. I am also not
very talented for trueing a wheel.
