Braided carbonfibre with red nylon as part of the weave. The red nylon not only looks pretty but also makes the bow softer, more flexible. If you find other Glasser braided bows too stiff, this may be the one for you - it certainly makes spiccato easy! (but to be fair, I can do spiccato with a steel rod, it's about the only thing I ever learned well!). Available in full size only (3/4 for bass).
By the way it also seems to get called the 2005BCFR or the 2015BCFR. Same bow.
Probably only available in the UK from me because the UK wholesaler does not import this one.
