As we head into peak gravel racing season, with marquee gravel events like last weekend's The Mid South, and gravel events like The Gralloch, Dirty Reiver and the OG of gravel racing, Unbound Gravel, are all on the horizon.

The best gravel bikes are constantly evolving to the ever-increasing demands of pro-gravel racers, but the one bike that still holds its own, with a gravel heritage that stretches back to 2014, is the Specialized Diverge.

Right now, Tredz has a flash sale on, and you can get the Specialized Diverge 4 for as little as £2,159. There are three models discounted, including the Specialized Diverge 4 Expert Di2, discounted at Tredz by £800, to just £4,699.

Therefore, if you’re looking to get what is one of the most versatile gravel bikes on the market, which our tester called “an outstanding companion for riders who spend most of their time off-road.” Then the Diverge is more than worthy of your consideration, especially at these prices, and will have you equipped for your best summer of gravel riding.

In our review of the latest Specialized Diverge, our tester was full of praise and awarded it with a 4.5 out of 5-star rating.

Review highlights included its well-thought-out design built specifically for gravel riding and racing, the range of price points and build specs that offer the same geometry and compliance, and the big tyre clearance and balanced compliance.

We reckoned the Diverge delivered "joy through stability and a sense of unstoppable momentum," and our tester added, "With its long wheelbase, low bottom bracket and generous clearance, it really felt like a freight train on gravel — fast, confident and composed. Once fitted with bigger tyres, it becomes an outstanding companion for riders who spend most of their time off-road."

The Diverge was summed up as "a genuinely exciting bike in a category that continues to evolve with every model year."
