Punctures – Park to the Rescue

Today’s ride was endurance training (Strava Ride) and I got a puncture, it really took the shine off what was turning out to be a great ride despite the fine rain. Until recently punctures seldom were a problem on my commuter bike. Now I’m doing longer bike rides that take me further away from home I always take the essentials, as I explained in a recent Bike Ride Essentials post.

Yet again the Park GP-2 Super patch has come to the rescue. I’ve tried other glueless patches in the past on my daughters bike and they failed within 24 hrs. Yes they get you home, but then you have to change the tube or patch it properly. It’s more hassle and I’d rather do the job right first time.

I have found the GP-2 patches a permanent fix. To my misfortune I’ve had two recent punctures, but this has proved to me that the Park glueless patches live up to their name. They are easy to fit and instantly seal the puncture and so far have lasted a few months with no increase in the frequency I have to pump up my tyres. However, as my inner tube shows three punctures…

… I need new 27.5″ commuter tyres!

The tread is still looking good on my Schwalbe Marathon tyres even after 22 months of daily commutes and at least 5000 km of riding. I bought them on 28th February 2015 and the 3mm ‘GreenGuard’ puncture protection belt (Schwalbe Level 5 Protection) has done me proud until now. I don’t think I got a puncture within the first 12 months. I got the second puncture within the last few months, and the third puncture today. However, each puncture has occurred within an inch or so of the last one. I think the GreenGuard is damaged significantly in one specific area and a weak point has developed.

These tyres are relatively heavy, so as I now plan to replace them I had to do a little bit of research. I wanted to know if I could get a tyre with better puncture protection which was lighter. I thought I’d share my research with you.

Schwalbe Marathon 44-584 (27.5 x 1.65 Inch) are 820g each (level 5)

Schwalbe Marathon Plus 40-584 (27.5 x 1.50 Inch) are 920g each (level 7)

Schwalbe Durano E 40-584 (27.5 x 1.50 Inch) are 560g each (level 4)

Schwalbe Marathon Supreme 42-584 (27.5 x 1.60 Inch) are 470g each (level 5)

Schwalbe Kojak 35-584 (27.5 x 1.35 Inch) are 410g each (level 4)

The answer appears to be no! I can either get the same level of protection and buy the Marathon Supreme tyres. That will save me 700g in total compared to my current Marathon tyres.

If I buy the ‘Flatless’ Marathon Plus tyres I hope to have fewer punctures and would have to put up with a 200g weight penalty.

As I really hate punctures I think my decision is simple. I’ll buy the Marathon Plus tyres and lose the weight off my body instead of the bike.

  1. Nice blog… As they say, it’s usually easier and cheaper to shed the extra grams yourself instead of paying through equipment. FWIW, once up to speed the weight has little bearing on performance… However, once you hit the hills it bites back. Good luck with that 100 and see you around.

    1. Cheers Rob. I’m down 1.3 kg since Christmas Eve. I hope to ride with you all again soon. My knee seams all better and I have just been given a pair of road mudguards, as a belated Christmas present. Eventually I’ll find the time to fit them on my vintage road bike (Vicky), and then she’ll be ready for winter rides.
