Most bikes come with gears but are they the right gears for the type of riding you do? Cycle Surgery's chief mechanic Andrew Brown runs through your gear choices and how to fit new gears

In our last bike maintenance video we showed you how to set your gears up for maximum shifting efficiency - in this video we take things a stage further by looking at the different gear ratios options available to you and how to fit then to your bike. 

If the standard gear set up on your bike doesn't suit the terrain you ride over or your riding style - you can change it for something more suitable by swapping out the front chainrings or chainset and/or the rear cassette. It may sound daunting but with the right tools and some knowhow supplied by Cycle Surgery tech guru, Andrew Brown it is totally doable. 

The whole series of our bike maintenance videos is available now on Youtube to help you get to grips with the essentials of keeping your bike running efficiently all year round.

Plucked from the obscurity of his London commute back in the mid-Nineties to live in Bath and edit bike mags our man made the jump to the interweb back in 2006 as launch editor of a large cycling website somewhat confusingly named after a piece of navigational equipment. He came up with the idea for road.cc mainly to avoid being told what to do… Oh dear, issues there then. Tony tries to ride his bike every day and if he doesn't he gets grumpy, he likes carbon, but owns steel, and wants titanium. When not on his bike or eating cake Tony spends his time looking for new ways to annoy the road.cc team. He's remarkably good at it.

Missed a few options out, double sub compacts 48/32, 46/30 available now by FSA, also Absolute Black do rings for most compacts to reduce the chain rings. 

Also MTB chainsets work perfectly on road setups if you  still want even lower gearing.

There are 11-34 Shimano or 11-36 SRAM 11 speeds.   


Di2 currently has a triple front derailleur which works perfectly with 48/36/26 Doere chainset though it was designed to work on MTB groupsets of 42t or less.
