Brakes and stuff

We’ve been looking at brakes, with over a million disc braked bikes recalled due to the risk of the quick release lever impeding the front brake.

If this puts you off discs, there’s always the direct mount rim brake option and we’ve looked at whether this is the future for rim brakes. And if you’re looking for a new groupset, it’s worth checking out our video review of Shimano’s Ultegra groupset below.

We’ve also looked at the new Tiagra 4700. Ten speed it may still be, but otherwise it’s a huge step up from its predecessor and a fourth-tier groupset worthy of its place in Shimano’s arsenal.

We’ve also published guides to rear lights and tyres to keep you rolling safely through the dodgy weather to come.

And GPS news

And on the subject of GPS, we’ve asked whether pro teams are using mobile phones along with the new sharing functionality which is finding its way into Garmin’s products to get around the ban on using race radios in some races, and for their directeur sportifs to have better information on how a race is progressing.
