Bon Jon Pass Review: “An Exceptional Tyre”

“An exceptional tyre that will make you faster and happier.” That was the verdict when the British web site http://www.road.cc tested our Bon Jon Pass tires recently. When we hear positive feedback, whether it’s from a professional tester or a customer, it makes our day.

I smiled when I read the calculation of the weight savings. It appears that, on average, spending a British pound ($1.28) will make your bike 1.91 g lighter. Based on that metric, the tester explained that choosing “the Compass Bon Jon Pass Extralight over the Schwalbe G-One Speed was ‘worth’ £157 of savings elsewhere. Ergo, at £67 RRP, the Bon Jon Pass is a ridiculously cost-effective weight saver.” I’m not sure about the math, but it does show that lightweight tires are the easiest way to shed significant weight, especially with wide tires where the weight differences can be quite large.

More importantly, the tester liked the supple casing and the excellent grip and comfort in the real world of the Scottish Highlands: “I hardly noticed broken patches of chip seal, or small gaps and lips of manhole covers. I found myself thinking up tests for what I could and couldn’t feel through the bike’s contact points.”

Negatives? Tubeless setup with supple tires is inevitably a bit trickier – the fit between tire and rim must be ‘just right’ and the thin casing is more likely to leak air until it seals. And his riding partners apparently weren’t always happy: “I realised I wasn’t signalling road surface irregularities as much as I should be to my sub-30mm-shod brethren following behind.” Until they switch to supple, wide tires, too…

No bike test would be complete without commenting on performance – “These are fast tyres, period. World-beatingly fast.” – and price – “I believe they are worth every penny.” 

There isn’t much we can add. We developed our tires because we wanted faster and more comfortable tires for our own bikes. When others enjoy them as much as we do, it makes us happy, too.

    I started using these tires this year/ I was surprised how fast and grippy these tires are. I am a fan, and will not ride with anything else. A great tire!

    My wife and I have Bon Jon’s on our road/ gravel bikes and riding around Portland, Oregon’s chewed up road surfaces has never been so smooth. That and the easy transition from pavement to gravel is so nice. This is truly the “one tire for all conditions”!
