Just put my Helius ST together (finally) and I find the cockpit a bit tight. Normally I ride XL in other Nic frames but bought a large in the ST. I'm about Whafes build and height I think, 6ft 3.5ins, 95 kg? Currently I have a seatpost (Thomson) without lay-back and a stem (Thomson) 45mm x 1.5 inch. So is a 70mm stem ok for this type of bike, in which case what make? Thomson only do 45mm, so I was thinking of fitting a Race Face Diabolus 70mm x 1.5 and a Diabolus 30mm dia. seatpost with 20mm of lay-back. The choice in 30mm is rather limited and I would rather not have to use a shim. Any suggestions and advice would be welcome. Thanks.
