I’m really surprised how poor the Bon Jons tested. Was it the EL version? I’d think they would test very close to Compass’ 44mm tire - is the difference because the 44 is the EL and the Bon Jon is the standard casing?It might not be clear, but I tested BOTH the regular and EL versions of the Snoqualmie Pass tire. They "bracket" the Strada Bianca Pro in the list. It appears that for that model, the EL version is worth only ~1-1.5W per tire between 20-30 kph. That has me thinking the regular version might be the better call. Early on in running the EL versions I suffered a sidewall cut that probably would've been fended off by the regular model since there's more rubber in the sidewall. The EL seems to have a really light rubber content in the casing...such that when run tubeless there can be quite a bit of "bleed-through" of the sealant.
The Bon Jon was standard casing, and I would expect the difference for the EL version to match the Snoqualmie Pass.
Thanks Tom. I’ve had the same experience with the Compass tires in terms of sidewall weeping in the EL version when setup tubeless. In fact I’ve given up completely using any of their tire tubeless (I have a lot!). I now use latex tubes on all of them - even the 650b 48s (26 inch Michelin mtn ones).
More questions: were you testing the Bon Jons and Snoqualmie tubeless?
Any idea why the Bon Jons are so much slower compared the same casing for the Snoqualmie? There isn’t much rubber on those the Bon Jons and they *feel* supple. Seems strange they would be slower.
