Suspension Losses Confirmed

Great post from BQ and Heine “Higher tire pressures don’t result in faster speeds – even on smooth pavement. Replicating results is a crucial part of science, which makes the new results an important milestone in the understanding of bicycle performance. No longer is it just Bicycle Quarterly talking about suspension losses and lower tire pressures – the science is becoming widely accepted.” (well, hopefully it is!) (Though there are plenty of Luddite-Thinkers out there…who still run 120, 130 psi on road tires… ugh) The many False Narratives in cycling are enough to make one ill…

Recently, Bicycle Quarterly’s experiments on suspension losses have been replicated and confirmed: Higher tire pressures don’t result in faster speeds – even on smooth pavement. Replicating results is a crucial part of science, which makes the new results an important milestone in the understanding of bicycle performance. No longer is it just Bicycle Quarterly talking about suspension losses and lower tire pressures – the science is becoming widely accepted.

When Bicycle Quarterly’s tire tests (below) showed that higher pressure didn’t make your tires faster, few people believed it. Back in 2007, everybody “knew” that pumping up your tires harder made them faster.

We had doubts, too. So we tested again and again, and our results always were the same. We concluded that it was true, even if it went against the accepted wisdom of almost 100 years of cycling knowledge.

Looking through the literature and talking to experts like Jim Papadopoulos, we found a mechanism that could…

  1. Hey, I’m down to 100 psi on 24’s (the biggest I can fit on the Venge is 25). Below that, in the 80’s, it feels like trying to ride a $5,000 CF road steed through mud.

    • Alrighty Jim!Sound good to me. 100 psi will provide you better contact and feel for sure over 110 or 120. I’m on 28mms now, at approx 94/90. Soaks up bumps well and good traction too.

      • Yeah, we looked at 28’s… Just don’t have the clearance. I won’t lie, I was mighty happy with the difference between the 24’s at 100 and 23’s at 125. It is a much better ride.

      • Yes, the clearance is definitely an issue on many bikes. The Conti 28mm rear just SQUEAKS by…and I mean just. But I too am very happy with the increased compliance, at my age and with the arthritis, I don’t need to be jostled around anymore! 😀
