Schwalbe Ice Spiker Pro spike failure

Need 29″ studded bike tires? Not that many options out there. I’m aware of:

  • Kenda Klondike (2.1″, 400 non-sharpened spikes, 1464g)
  • Nokian Extreme (2.1″, 294 sharpened spikes, 990g)
  • Schwalbe Ice Spiker Pro (2.25″, 402 sharpened spikes, 1170g wired / 890g folding)

2 years ago I wanted my winter tires to be wider and was ready to pay for the higher-end lighter option, so I bought the folding Schwalbes.

They hold fantastically on ice and pull fantastically in snow or slush. One serious disappointment was that the scale showed 1040g, or 15% over the specified weight.

Schwalbe studs losing pins

Now the second one. In just two winters, nearly all spikes from the central row of the rear tire have lost their hardened tips. The soft (probably aluminium) base squeezed down and became nearly flat, hidden inside the rubber knob. Some of the (former) spikes are pictured. It is relatively easy to replace the spikes, but I have a feeling that the rubber base is now weakened and the replacement drops out quickly.

The central row is probably not critical; two adjacent rows are in contact with the ground, and have lost just a few spikes. One must note that Kenda and Nokian just do not have that central studded row.

  1. I seldom cycles in winter, but a few years ago I bought tires Continental Spike Claw-120 for travel in Alps in December. There were not any spikes on the two central rows of the tires at all and I felt myself uncomfortable on the ice. I did 1000 km on the tires in Alps and about 1000 km in Finland. No one spike was lost. Last winter I bought Schwalbe Ice Spiker (only one tire) and realised immediately it was much better choise. Then I sold Continental Spike Claw-120 and the new owner upgraded them. He added 120 more spikes on each tire.

    • I’d say that these two central rows are absolutely essential – I almost do not see the point of selling Claws-120 alongside with Claws-240.

      • I don’t see any reasons too. I’d like to add there are 240 holes for spikes in Claws-120 as well as in Claws-240 but spikes in the two central rows are absent.

  2. I own Schwalbe Ice Spiker Pro 27.5×2.25 with Alu-Spikes. I put them on only when outside is below 0 and it seems to stay for longer period. Tyres are superb to drive. On the asphalt, grass, mud, frozen lake with pure ice.. they hod bike like it should be. The only thing – rubber is weak and spikes too. I mean this tyres will not last long. I drived 2 seasons (couple of weeks in a year) when it is below 0, so in general after 700 km they look like 60-70% used. I suppose they can hold about 1000-1200 km (90% asphalt) before you throw them away. In general I use them for safety reasons, and when I have time – for fun (driving on the frozen lake is awesome). I will try to replace spikes, maybe this will prolong lifetime, however, each wheel needs about 200 spikes (if one changes only central spikes) so it results in 400 spikes for both wheels. Price for 400 spikes + tool is equal to the price of one new ice spiker pro. So I am not sure, either buying a new set of tyres or replacing 400 spikes…

    • From my observations I have concluded that replacing spikes does not give much extra life to the tire. The rubber sockets which hold the spikes weaken faster (that’s a property of Schwalbe Ice Spiker Pro-s: being much lighter than competing models, they just have less rubber around the spikes). I had installed several fallen out spikes, but the replacements dropped out almost immediately.
