I own a Tyrell titanium bike PK1. I customized it with Shimano Ultegra components and I really love this bike which is just so good on the road, its silent, smooth (riding), fast and light. I'm looking for a foldie lately which I considered Dahon dash (out of stock) and Tyrell FX. However, I realised that there is a new "powerful" serie coming up soon in 2013, the Tyrell FSX (foldable). It is fixed with the SRAM Force components and the Ultremo ZX wheels, really high-end. Ultremo ZX is really light and fast (150psi). I heard that there is also an improvement on the fork which is lighter than my current Tyrell fork. The frame is really beautiful and part of the cables are now hidden in the frame in this new serie, wow... impressive!!! The price is not gonna be cheap for sure as I can see that the components and set up are even higher end than my current titanium bike at home. I expect it to be easily above S$3700 or even S$4000 up. Hmmm... I am loving this, but I hope that they have the bike and rims in red. Red is beautiful on this bike!!!
