The chin stay of the carbon capra is aluminium.
There was an issue when the bike was first released, this resulted in frames being replaced under warranty, that issue was fixed by design change but the cracked frames fear mongering has lingered. I don’t think there is an issue now.
I like mine, I have a carbon capra pro. It was great at Hopton uplift yesterday, it excelled in the roots and was really nimble. The suspension is a bit excessive for a lot of trails and it irons out some of the fun. It is close to being a dh bike but very light/nimble and climbs well. There is no catch. It is a quality product at a great price.
