The Bon Jon Pass is our Goldilocks tire: at 700C x 35 mm, it fits bikes that have extra clearance around the Stampede Pass (32 mm), but not enough space for a Barlow Pass (38mm). We name our tires after the passes that inspire them: Bon Jon Pass is a remote pass on the Olympic Peninsula. The moderate gradient allows you to let your bike fly, and these tires are perfect for the smooth gravel surface of the pass and for the chip-sealed asphalt that covers the approach.
The Standard casing is our more affordable option: comfortable and fast, yet also strong to withstand considerable abuse. The Extralight casing takes the performance, comfort and feel of your bike to an entirely new level. The Endurance casing is reinforced for extra sidewall protection and puncture resistance, while retaining the speed and comfort for which Rene Herse tires are famous.
SEALANT RECOMMENDATION:
This tyre is tubeless-compatible. If running tubeless on Rene Herse tyres we recommend using Orange Seal sealant with these tyres. Check out Rene Herse's guide to setting up tubeless tyres here.
TECHNICAL SPECS
The supple casing of our Rene Herse all-road tires rolls smoothly over surface irregularities.

Fitted standard case Bon Jon Pass Tyres to my new Focus Paralane – only clocked up 150 kms so far – they fitted easily on tubeless rims and they ride SMOOTHLY at 50 psi – (I weigh 92 kgs) – there is no reduction in speed compared with standard road tyres – hope the cost is justified in the long run

They were a pain to install and one refused to stay inflated (replaced under warranty by the wonderful folks at Commuter Cycles). I had 1 puncture and the rear tyre wore off its tread pattern after 2000km but I still rate this as the best slick tyre I’ve ever owned, edging out 32mm Continental GP5000s.
For one, they’re massively more comfortable and confidence inspiring on pavement and gravel. Subjectively they’re a smidge slower than the GP5000 but I still prefer them because of their overall feel.
I’m not sure I’d replace them with the same. I’ve moved into wider tyred gravel type bikes and won’t go back. But for under slicks that are under 40mm they are my favourite.
They measure 38.5mm installed.

Had a few of these 35mm now, which I run with tubes. Not hard to fit and I find them durable. Top marks for comfort, smooth rolling and grip. Not a cheap option, but the best all-round road tyre I’ve tried.
