I use the kit for the Forerunner 305. Super supplement for those who are using the Forerunner both running and cycling. The bike mount is fastened with cable ties on the handlebars, the Forerunner can then be "clipped". The bracket keeps super, even with strong shocks (Mountain bike). The bracelet for running is also without criticism! I highly recommend this kit because it is a truly practical solution for multisport athletes.
