MichelinC4 Protek Max 26" MTB Presta Tube(Return to Product Page)

Expedited shipping as usual with great service.

I put these in new Michelin tires so don't expect

a leak or flat in coming months.

I'm tired of Ebay 26" tubes (4) that

leak at stem or blow out within a month actually

with the bike parked.

Some what difficult to pack into the tire but

with extra care and time it works. Mounting the

valve stem without a slant is a wrestling match.

I run them at 78 PSI although the tire is

rated 86 PSI and they leak down 6 PSI or so

every 7 - 10 days just like all tubes.

high pressure tires need a good tube and this is it

forget about patching this tube when it does fail

I use this on my MTB with Continental street tires. I use the bike on roads, trails and hard pack gravel. I've gotten punctures with this tube but the slime slows the rate of air loss and it's enabled me to get home without changing the tube.
