Gecko carbon rim in 650b or 700c size. The hookless bead makes the rim lighter but means you can’t run high pressure tyres, we recommend up to 80psi which should be enough for most riders. The 21mm internal width is perfect for tyres for road tyres from 25c up to gravel tyres at 50c or 2″.
Due to supply problems we are moving the Gecko to a symmetrical version. Currently we have the 24 hole 700c rim in the symmetrical version which weighs around 331g.
