JRA Gecko carbon rim


Gecko carbon rim in 650b or 700c size with a hookless bead making the rim light and strong. The 21mm internal width is perfect for tyres for tyre sizes from 25c road up to gravel tyres at 50c or 2″.

The Gecko is our lightweight carbon road and gravel rim. Hookless bead increases strength but some road tyres are not compatible – please check that your preferred tyre is compatible with hookless tyres.

Some of our Gecko rims have an asymmetric profile (where the spokes are offset to one side to slightly increase wheel strength) but due to production issues the 24-hole, 700c rims are standard symmetric. They still build into strong wheels but we have lowered the recommended maximum rider weight from 90kg to 85kg for these rims.

The 28-hole rims have a stronger (slightly heavier) carbon layup for larger or harder riders or use with carrying luggage.
