Tubeless!

“They’re not meant to be used with tubes”

Summary:

Easier than expected

 

Thus chided the very patient Elisabeth Foot from Schwalbe when I had complained that my “bullet proof” G-One All rounds were in fact thorn magnets.  She also recommended Big Ben Plus or Marathon Plus MTB, but both came in only 2 inch versions and I wanted at least the 2.25″ our  bikes came with, as well as the lowest rolling resistance I could get.

When I got home from our 3 months around very mixed surfaces all over Europe I decided to give tubeless a go.  We had been using Schwalbe Rocket Rons and Racing Ralphs, and had about 8-10 flats and had replaced one tyre so it was time to try something new. I’m still not sure that the G-Ones 60-584 (27.5×2.35) are going to be the all-rounders I need, but I have them, they are Tubeless ready, or Tubeless Easy as Schwalbe brands them, so they will do for starters.

However, Orange sealant proved to be the first stumbling block, along with Gorilla Tape, both highly recommended by various Facebook groups, and both unobtainable in NZ!  What’s the point in luxuriating in Sunday shopping hours if you can’t buy anything except by shopping online, usually from those closed-on-Sunday European emporiums. By the time they had arrived I had seen enough youtube videos to be an expert, although I was fully prepared to visit my LBS to have them do it properly after I had failed, so I launched into installing them..

The best advice gleaned from all those videos was

  • remove the valve core before seating the tyre to allow for greater airflow
  • give the rim a quick light spray of silicon lube before pumping which allowed the tyre to seat well without even that satisfying pop
  • save  a few bucks by cutting a valve insert out of an old tube instead of buying new custom one. (not the best idea it turned out)

The first attempt went well.  New G-Ones are devilishly hard to get onto the rims, they seem to be tighter than any other tyre I’ve fitted, but once on, and without sealant to begin with, they eased up onto the rims with a nice tight fit after the recommended quick light spray of silicon. I have a good pump (Topeak Joe Blow) and even though I’m no longer young and fit I could seat these bigballoons  without raising a sweat.  I left them overnight, noticed that one was deflating slowly and worked out that it was my chopped down valve insert leaking, gave it a 50km test run to make sure, then replaced it with a proper one.  That’s a messy job with the sealant splashing everywhere but luckily it cleans up well with a damp rag, and the properly made insert works a treat.
