TEC service

I have had placed TEC pipes on bike years ago and have finally got around to changing the original suspension. As always the service from TEC was exceptional. Looking forward to getting these on the bike & enjoying the improvement they will make.

Gas shocks.

Really pleased with the the service and the dispatch time for items ordered, my only gripe is that there were no instructions or a C spanner. I don't mind paying extra for the items that I think should be included. Other than that I love your products.
