To achieve standout performance, every tube on the TCA-1 is the product of
countless optimisation cycles targeted at pushing the boundaries of what is
possible for an aluminium frame. Exploiting the full range of hydroforming,
taper butting and CNC machining technologies to create something truly special.
To build a confidence inspiring ride, steering and braking performance are key.
The TCA-1 features a double butted top tube and triple butted down tube mated to
a super stiff 1-1/8th” to 1.5″ tapered head-tube. Not content with only that,
the Tresca engineers have added wide section gusset to take handling to the next
level.
Tapered chain stays, a flared seat tube, and a wide down tube base combine to
provide a superiorly stiff bottom bracket for exceptional pedalling performance.
Up front our aerospace-grade carbon fibre composite fork with tapered steerer
provides reliable comfortable control. The carbon fibre composite fork delivers
the perfect blend of high strength to weight and also helps to reduce road buzz
for a more comfortable cockpit.
For reliability, serviceability, and squeak free happy riding, the TCA-1
features a tried and tested threaded BB.
To keep things neat and tidy, the bespoke internal cable routing has been
carefully engineered to allow simple installation and keep cables protected.
The TCA-1 features dropped seat stays to increase vertical compliance and
improve ride comfort. Moving up the seat stays, we arrive at the tuned 25.4 seat
tube optimised using the latest FEA technology. The seat tube features a unique
fin profile used to control deflection in the mid to upper section and fine tune
the balance between pedalling efficiency and comfort.
