Presta valve - Giving It another chance

I've thought of changing the tubes of my Marin Alpine Trail 29er from Presta valve to Schrader due to the former's frequent flats.

But, when I saw this Maxxis welter weight Presta valve tube, which boasts that it's "puncture resistant", I'm giving Presta valve another chance.

I bought three (3) tubes, which depleted my wealth by P750, and installed one in my front tire.  The other two serve as spares.  The rear tire has Continental tube.  Both tires were inflated at high pressure.

Let's wait and see what would happen!  And, I'm crossing my fingers.

It's not just two but three flats

I cut short my Easter Sunday ride due to two flats (both rear) in a row.  When I arrived home, however, I noticed the front tire was flat too.  Holy cow!  It's still inflated when I loaded it in the car.  I haven't fix it yet; as, I have no more spare.

Now, I'm not just tired but really fed up with this frequent flats!  Aside from the troubles of replacing the tube, it's escalating my costs.  The price range of a tube is from P250 to P350.

Meantime, I'm sidelining my Marin Alpine Trail 29er while looking for solutions to the problem.

Possible solutions:

• Look for tubes with Schrader valve
• Use 26er or 27.5er tubes with Schrader valve
• Make the holes of the rims bigger to fit the Schrader valve.

What do you think?

Easter Sunday ride - UP Diliman

Easter Sunday celebrates the resurrection of our Lord Jesus Christ from the dead.

With my Marin Alpine Trail 29er (TweetyPot), I went to UP Diliman this morning.  I hadn't completed yet my first lap of the Academic Oval, my rear wheel got flat.  Holy shit!  It's a brand new tube.  After replacing the damaged tube with an old one, I resumed my ride and tried the forbidden trails.  Then, after negotiating the single tracks at the University Avenue and Commonwealth Avenue, the rear tire got flat again.  Darn!  New and old tubes, they suffered the same fate.  Their Presta valve base were torn.

Flat again!

After replacing the tube with another new one, I decided to cut short my ride; as, I've no more spare tube.  I always carry two (2) spare tubes in my saddle bag when biking.

And, I'm already getting tired of the frequent flats due to torn Presta valve base.

Flat again

It's flat again!  Yes, the rear tire of my Marine Alpine Trail 29er is flat again, which I noticed when I woke up this morning.

My guess the culprit is, as usual, the torn base of the Presta valve.

I didn't fix it yet; as, we're leaving for Balanga, Bataan.

I can't ride my TweetyPot

TweetyPot (my 29er) has been out of commission since two weeks ago due to damaged tubes.

First, after pumping the front tire in preparation for a ride, it got suddenly flat. There's no time to fix it, I used AlitePot (my 26er).

When I got back home, I found out that the base of the Presta valve was torn. Thus, I replaced it with my spare tube. The next day, I bought another spare tube.

The following weekend, I noticed the rear tire's flat. The culprit's the same. So, I had to replace it with the new tube. But, while pumping it, it exploded. Darn!

I tried to buy tubes; but, they're out of stocks from well known bike shops I inquired from - Knobbies, All Terra, Bikezilla, Iron Bike, Sabak and Bike Town.
