Om 390 slits fort, så slits 288 ännu snabbare enligt deras hemsida:
288: Sticky Rubber Compund, which has been specially developed using climbing rubber technology. This rubber optimizes grip in wet conditions, however the trade off is it wears down quicker.
390: Endurance Rubber Compound. Our endurance rubber compound has been formulated for an optimal balance on wear and mixed terrain grip.
...sen vet jag inte om 390 hade samma material 2008, som idag (Endurance Rubber)?
