WTF! Specialised Turbo Pro - 2 punctures in one ride!

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

WTF! Specialized Turbo Pro - 2 punctures in one ride!

I went for an 85km ride yesterday on roads and MUPs yesterday, with reasonably good paved surfaces with a few odd twigs and leaves.

I'm riding with 26mm Specialized Turbo Pro tires on my Roubaix.

After stopping mid-way for a coffee for 20 minutes, I noticed the front wheel was almost completely soft. A quick inspection showed a small thorn, no more 5mm long in total was lightly lodged in the wheel. I sighed, and duly changed the tube. FYI, the Turbo Pro tires are super tight on the DT Swiss rims and a PITA to get back on.

I put it down to chance (no one else in the 15 strong peloton had the same bad luck), and we carried on.

I made it home and then noticed that my rear tire also felt pretty soft. I pumped it up to test it, and sure enough after a couple of hours it was barely holding its shape. Overnight it completely deflated. No obvious foreign objects, and no obvious leak after pumping it up to 100psi - must be a slow puncture somewhere.

The front tire (which I changed on ride) has a similar slow puncture - I pumped it up at home, but couldn't hear or feel the leak. I guess I'll have to put it in soapy water to see if I can see any bubbles.

So, is this just plain ol' bad luck, or do the Specialized Turbo Pro tires have very little puncture protection?

I've ridden for over 6 months (min 600km / month) on really crappy urban roads with Continental GP4000S IIs and Vittoria Voyager Hypers and never had a puncture. I ridden Centurys on rural roads and no punctures. To have 2 on one relatively short road ride seems unusual .

Time to change tire brand, or put it down to bad luck?

Bad luck. I ride mine on dirt & gravel roads some. I have a gash in the rear tire, but it's holding up. I booted it with a dollar bill as insurance.
I did pinch flat a front, but that was a pretty big rock on a fast downhill. No tire damage, though.

I don't know these tires from Adam. But, yeah, it could just be bad luck. Earthquakes sometimes occur in clusters. Sometimes flats do too. When I've encountered such a thing it is almost always in either the Spring or Fall (i.e., sharp gravel washed onto roadways by Spring rains; thorns and other debris in the Fall, etc.). Thankfully it is rare; or has been in my own experience.

Sorry to hear about your rotten experience.

These are poor performers with respect to flat resistance.

Search it up and you'll see...

The tubular version has been 'golden' for me. But as a race tire it wears faster, a worthy trade-off for me.

Thanks. Sounds like the Turbo Pro isn't a great choice on non-pristine roads. The tires are too new to just bin, so I'll keep them another go on the assumption that I had particularly bad luck on this occasion. I'll carry 2 tubes on the next long ride, just in case!

But if these tires prove to me puncture-magnets again, then I'll be looking for something else. I have a spare set of lightly used 25mm Conti GP4000S II, so these would be my goto "know quanitity", although I have heard that their side walls are also very thin. Probably not a huge issue on the road unless you hit something side-on.

I have those exact tires in clinchers. I only have about 300 miles on them, but so far, so good.

Is this any better or worse than your experiences with other tires?

Sounds like I just hit a bad patch of sharp stuff (I did ride over grass for 100 metres) and got a couple of slow punctures in both tires. It's interesting that I didn't even notice the punctures when riding the bike and the deflation happened over a period of about 30 minutes. The holes must have been very small and I might have been able to save time on the ride by just pumping up the tires a little every half hour.

I'm new to cycling. Just started in June. So I can't really compare to other tires. The shop says they still have a lot of life on them. We have lots of paved trails here and tires trnd to last a long time vs on roads.

I'm using the Specialized Turbo Cotton with latex tubes ....

brilliant .... very grippy and fast ...

over 800km puncture free except for 1 pinch flat when I experimented with air pressure and had the front wheel too soft

they still look brand new

Beauty of cotton is they are machine washable. If you do put them in the dryer, just be sure to set to low heat or they will have to be used on the kid's bike.

I don't use these in the wet .... it's on my 'fast bike' which I use for quality rides. Brilliant and roll fast

I will be trying tubeless for winter on this bike .... I have tubeless ready rims (HED Belgium Plus wheels), and I will be trying 2017 IRC Formula Pro RBCC tubeless road tyres

Just a matter or circumstance.

I've had the exact opposite experience, sidewall punctures with the GP's, and not a single flat on the Turbo Pro's yet (knock on wood) which i've rode 3-4 times a week since May...and i've hit some gashes on the road that have take my breath away on them. Did my first metric century with them 2 weeks ago, they held up well.

I say give Schwalbe One V-Guard's a try, my most bulletproof tire.

I had good luck with mine. I put about 2000 miles on the rear and 3000 on the front without a puncture. The front had cuts 3mm long down to the puncture layer and rode fine like that for over 1000 miles. Neither was fully worn down when replaced but both had only the slightest hint of a wear dimple showing. Currently running 28mm schwalbe ones which I like so far (only 400 ish miles).

Now my one foray into GP4000-IIs tires was very disappointing. They felt great but I only got 400 miles on the front and 800 on the rear before sidewall cuts rendered them dead

I have thousands of miles on the Turbo Pros. They only problem I've every had was on my Mavic Cosmic Elites. No matter how much pressure I would run, I would pinch flat. In less than 500 miles I had flatted over 20 times. Was ready to call it quits and actually started riding on patched tubes (normally I carry them in case I flat or to give to someone if they flat.) The only tire I ever had problems with on those rims. After switching to carbon rims, I can count on one hand the number of flats.

I'd say bad luck, but no one thing is perfect for everyone.

I have a Spesh Turbo Pro clincher on the back wheel with about 3000 miles and no punctures so far. But I inspect the tires every few weeks. First I let the air out and then pinch the rubber so that any cuts or embedded debris is exposed as they open up. I can then pick out glass and clam shell shards or other puncture causing bits. I'm well satisfied with the tire and expect to get another 500 to 1000 miles out of it. And by the way, this is a nominal 28mm tire on a Velocity A23 rim and actually measures 29 1/2mm.

Great racing tires: supple, fast, very confident in the corners. But not super puncture resistant or hard wearing, which is why I have them on my race wheels. I have Michelin Pro4 Endurances on my training/commuting wheels.

my experience for winter tyres (on a road bike)... I commute reasonably far distance throughout the year (1400-1500 km/month):

Schwalbe Durano Plus .... you wont find a stronger puncture resistant road tyre than this (marathon plus has the same puncture rating as these) ... I've never had a puncture on these

Continental Grand Prix 4 Seasons .... faster rolling, reasonable/good puncture resistance and last long .... I've had a few punctures on these, but the glass that caused the punctures would have flatted most tyres ... I will most probably buy these soon for my daily commuter
