Quick comment about "Ocean laminates " run by Marcin .
Ocean offer via Ebay basic seat shells ( un drilled and without fixings or mounts ) for the DIY boys and girls at affordable prices if you don't mind drilling and fabricating to complete .
Daytime he is employed at the ICE works producing the "high end Glass/Carbon " VTX + Sprint X seat shells .
See the videos and note the prices have risen since May 2019 .
Just for the record.
I have the largest stock of new ICE spare parts and accessories in the UK (other than the "works" of course)
Also the sole supplier of specific parts for ICE B1 + B2 + B3 that includes frames !
These much loved two wheel recumbents were built and designed by ICE ten years ago .
However I also deal in pre-owned + shop soiled and re-furbished ICE Parts with sensible savings on new .
Another speciality .......I have vast stocks of new and used spares and parts for other well known brands
Plus I'am now regarded as the "one stop" source for Windcheetah and Kingcycle + Radius Peer Gynt owners .
If you desire a HUB gear box ,.,.such as Alfine + Sram or RH 14 ?? or Son Hub wheel dynamo or perhaps a fairing
I often have used examples on offer .........just ask
Hope that helps
