Perhaps the problem is your manner of phrasing the question. I read your question as: Do you consider XXX as high enough pressure for smooth road riding? On Thu, Jul 6, 2017 at 8:05 PM, 'Mark in Beacon' via RBW Owners Bunch < rbw-owners-bunch@googlegroups.com> wrote: > Am I confused or are you c

I should have mentioned that the 30/35 PSI is with a 240lb rider. The Rat Trap Extralights are mounted on Sun Rhyno Lite rims. That choice of pressures is based on what had worked for me with a pair of 2.15" Schwalbe Big Bens. When I tried the same pressures on the RTPs, they just seemed to work

And Keith's remark on rim width reminds me of something very pertinent; mine measure IIRC about 27 mm inside. Narrower rims of course would require more pressure, especially with such thin sidewalls as on the RTP and F Fred. On Thu, Jul 6, 2017 at 10:12 AM, Patrick Moore wrote: > On these tires,

On these tires, yes. It's actually 23 to 28, and that's front versus rear. I consider this the best pressure range for sidewall support and cushioning on combined dirt and pavement; if I rode dirt exclusively, I'd probably drop the pressure a few psi -- indeed, perhaps 20 f and 23 rear. If I rode

Yeah, Mark - i think you want you let air out, not add it! I just took mine off my all rounder and went back to the original 1.75 compass tires because it was so tedious to tune the bounce out. But, in my case, it was the rim's fault - not the tire's. Normally, the way to get a high-volume, su

I get what feels like bounce feedback when the pressure is too low. Maybe what I'm calling bounce is really...squish? I think I know what they mean, the kind of bounce when the tire is overinflated, but I only pumped them that high to seat initially. I will try a little ride with 50 psi for the

Digital gauge for bike tires -- forget make, but said to be accurate to a fraction of a lb per sq inch. I weigh 175. I'm not disagreeing, just wondering why RTPs need such high pressure when at least one considerably lighter tire needs considerably less, On Wed, Jul 5, 2017 at 2:57 PM, Philip Kim

ahh i was just noting why you may be seeing some higher psi run with RTPs from other, as 30-40 psi is a bit high for a ~50mm tire. On Wednesday, July 5, 2017 at 2:52:18 PM UTC-4, Patrick Moore wrote: > > I doubt that the RTP casings are thinner than those of the F Freds. If > anyone can correct
