Boardman SLR 9.0S Bike Review
We test the Boardman SLR 9.0S in our latest four ride review.
In our four ride reviews, we take some of the world’s best bikes out for a spin over different terrains. View our full archive of bike reviews here including our head-to-head triathlon bike tests.
We’ve tested bikes from Boardman’s super-light SLR range before and been impressed, so when we heard they’d brought in the 9.0S with Ultegra Di2 shifting, we had to see how it would ride. The 9.0S has the same straight-lined shape for maximum efficiency and stiffness, with boxy chainstays and an oversized bottom bracket for power transfer. It’s immediately clear that the quick shifting of Di2 is made for a bike like this.
The 9.0 is a bike that loves to be ridden fast and in our interval session, the sharp, sure shifting of the Di2 gears on the 9.0S was perfect. Changes of pace are instant thanks to this and the firm frame, and the front end allows you to get low and stay aero. Acceleration is dulled only by the switch to Mavic’s Aksium wheelset – the
9.0 comes with pricier Ksyrium rims – but great overall value means we can’t grumble.
Despite entry-level wheels and the very slight weight penalty of the Di2 over standard gears, the 9.0S is impressively light. Take that low weight, the beefy chainstays, stiff frame and add Di2, and you have a fantastic climbing machine. Even at the lowest ebb of our winter fitness, the 9.0S willed us up steady slopes and even had us racing around on rolling roads. A wheel upgrade would make it even better.
Though this is a racing machine at heart, it doesn’t have you so stretched out that long rides are a chore, though female riders might want to swap in a shorter stem. Its stiffness means you will feel the worst of the winter potholes but most road buzz is soaked up without trouble. You might notice more noise from the cables than usual; some judicious zip-tying at the front helps and it’s a minor point on a brilliant bike.
