I spent over 3 hours in Sigma on a Sunday afternoon and found the staff to be very knowledgeable and friendly. They were able to give me advise from their personal experiences and I came away with bib shorts, tops, arm warmers, gillet, socks, sunglasses, tools, helmet, seat and seat post that proved to be perfect for my London to Paris ride in under 24 hours. If you want the right kit there is no better store in my opinion. I also took back a Lezyne under seat tool bag as the velcro strap kept on coming undone which they exchanged for another make with no problems at all.
