How to mount Schwalbe’s Procore System

Stefanie 12. July 2017

Schwalbe’s Procore System is a proven way to get more grip out of your tyres. But how do you mount it. Read on to find out more.

Schwalbe’s Procore tyre system has already proven itself on the market. But how does one install it? I had a chance to answer this question during Bosch’s eMTB Challenge in Riva, Italy where I outfitted my E-bike with it. Read on for the full report.

The Procore System

Schwalbe’s Procore is based on two chambers that are both set to different pressures. The inner chamber sits directly on the rim and can be pumped up between 4 and 6 bars. This high pressure holds the tyre’s bead to the rim and protects both. This means that the outer air chamber (the tyre) can be ridden with very low pressures between 0.8-1.5 bars. Procore is compatible with all tubeless tyres with 2.25” widths or larger and tubeless rims with at least a 23 mm inner rim width.

Step 1: Prepping the rim

Step 1: Prepping the rim

  • First the rim needs to be checked and prepared. That means taking off the tyre and old rim tape. A little brake cleaner can help with this.

  • Just to be sure, check the inner rim width to see if the new rim tape will fit.

  • After, the new rim tape needs to be installed under tension. To ensure there aren’t any leaks, start wrapping the tape two spoke holes before the valve hole and end two holes after it, creating a good overlap.

Step 2: Mounting the Procore System

Step 2: Mounting the Procore System

  • Start by carefully placing a hole in the rim tape at the valve hole.

  • Now the special Procore inner tyre (blue) can be installed. This is done just like a normal tyre by mounting one side of it first. The only difference is the silver line needs to be placed over the valve hole.

  • The Procore tube can be placed under the inner tyre next. Make sure the red Airguide is positioned with the ribbed sides facing outwards.

  • With the tube inside the inner tyre the other side can be pulled onto the rim. Here everything should be checked to be sure it is aligned.

Step 3: Mounting the tyre

Step 3: Mounting the tyre

  • All that is left to do is mount the tyre tubeless. This is done with a 60 ml bottle of Doc Blue sealant per tyre which cannot be injected through the valve because the valve will clog. After, the tyre can be completely installed using tyre levers.

  • Schwalbe’s Easy Fit can also help push tyre bead of the last bit of rim.

Step 4: Pump it up

Step 4: Pump it up

  • The Procore valve can be unscrewed at the base as well. If the valve is screwed in, the inner air chamber is filled and if it is screwed out the outer gets air.

  • First, the inner chamber needs to be pumped up to 3 bars and then the normal tyre needs to be pumped. Here, everything needs a minute to set (popping sound) before pumping the inner chamber to 6 bars and the outer to the preferred pressure.

Pros

  • Even when going hard, lighter weight tyres can be used.
  • More grip due to the lower outer chamber pressures without tyre folding over.
  • Increased puncture protection and burping becomes non-existent.

Cons

  • Takes longer to mount.
  • Increased weight.

On the Trail

Of course, once the Procore System was mounted I had a chance to ride it with the following bike setup:

  • E-Bike: SCOTT E-Contessa Genius 720 Plus
  • Tyres: Schwalbe Nobby Nic
  • Air Pressure: Inner chamber 6 bars, outer chamber F = 0.97 bars, R = 1.2 bars
  • Where: Riva with ca. 33 km and 1200 m of altitude gain

It was easy to notice the advantages of Procore right from the start.

It was easy to notice the advantages of Procore right from the start. The bike feels more at home on the trail, both up and down hill. Especially when things get rocky or full of roots, the tyres offer more comfort and grip.

Even after choosing some bad lines, which is easy to do in Riva, I didn’t get a flat. The increased weight of Procore goes unnoticed on an E-bike as well. Sharp corners and small jumps were also easy to take. Everything about Procore made my riding experience better. Though mounting took some time, it was straight forward and I can only recommend it.
