Yes they are Small Block8's. I haven't had them long but am loving them paired with latex tubes at lower pressures than I used to run. I found them predictable, but had to go into a few corners with some caution. Though, I've never ridden in conditions quite that bad before so probably would of eased back even with a different tyre and now reflecting on the race I've got nothing to compare the Block8's to in muddy conditions.
From the opinion of those there on race day, would a chunkier tyre actually have helped much??
I didn't have any problems with the small tread clogging up (except for 1 short section coming up out of that "rainforest creek" area which I didn't see anyone clear after the first lap). The track was just sloppy in general.
I did considered running something a bit chunkier before the race but stuck with the 8's when someone (Kenzo!!!!) said the track held up alright in the wet.
