It is important to get the right size bike, if the bike fits it will be faster, more comfortable, and easier to handle. You can also take into consideration the standover height to ensure you pick a bike that will be a good fit. If you measure your inside leg and ensure there is a minimum of an inch from the toptube to your crotch this will give you enough seatpost adjustment to find your optimum saddle height.
Generally we recommend: Small: Riders between 5ft 2in and 5ft 7in Medium: Riders between 5ft 6in and 5ft 10in Large: Riders between 5ft 9in and 6ft 2in X-Large: Riders of 6ft 2in +

A great blend of swaggering, speed-breeding stability sharpened up by instantly reactive, traction-chasing, short stem steering .... Alpkit resets expectations with its new hardtail.
"With slackest head angle, longest reach and shortest stem, the Sonder Transmitter is built for bombing, inspiring confidence to fully attack descents."
The Transmitter is a playful, all-mountain rig with some hooligan tendencies. It suits all manners of riding from trail centres to more natural riding to exploring wild bridleways. If you want a ‘one-hardtail-does-it-all’ then the Transmitter will do that in spades.
If you’re a numbers nerd or geometry geek you’ll recognise that while these are significant changes, they aren’t all that extreme and should result in a well rounded riding machine rather than something that only rides in one direction.
