Customer photo review of Headset Bottom Cup

This was part of converting a Canyon Sender 2019 to a single crown set up - mullet style 29/27.5. The added stack height of the lower headset helped balance the geometry. The headset fitted perfectly and runs super smooth. (I confess to buying the wrong lower cup the first time 🫣)

Needed a replacement bottom cup/bearing pronto as I was heading to France in the next few days. Delivered!

Customer photo review of Headset Bottom Cup

Used your headset and seattube clamp as part of a rebuild of an old hardtail where I tried to use as much anodised red componentry as I could. Your headset cups are nicely machined and pressed in perfectly, quality stuff.
