Simon says: don't buy a gravel bike without at least 50mm of tyre clearance – you'll regret it

Simon, a prominent voice from BikeRadar, has emphatically stated that prospective gravel bike purchasers should insist on a minimum of 50mm tyre clearance, warning that anything less will lead to regret. This definitive advice, published by BikeRadar, positions 50mm as the new baseline for a truly versatile and future-proof gravel machine, directly influencing consumer expectations and potentially manufacturer specifications.

This isn't merely a preference; it reflects a significant evolution in gravel riding. Early gravel bikes often borrowed heavily from cyclocross geometries and clearances, typically maxing out around 40-45mm. However, as routes have become more technical, and the industry has embraced wider rims and more aggressive tread patterns, the practical benefits of greater volume and comfort have become undeniable. Simon's declaration underscores a growing consensus that narrower tyres simply limit a bike's true capability on increasingly demanding terrain.

Ultimately, Simon's pronouncement serves as a timely, if slightly blunt, market correction. Manufacturers ignoring this trend do so at their peril; consumers, now forewarned, will likely demand nothing less.
