For the rider that demands and must have the best, the REILLY T640D is our flagship titanium road frame and available as custom or off the peg. Featuring ultra butted 6AL4V seamless main tubes that have a ultimate tensile strength of 1150MPa and density of just 4.42gm/cc, these numbers added to extraordinary design make the T640D staggeringly stiff but supremely comfortable. Lighter, stiffer and more compliant than 3AL2.5, this frame has it all and bags more. Designed for a tapered fork which adds incredible, sure footed, razor sharp handling.

The Builds

We have spent many hours in the saddle considering our perfect setup for the T640 bikes and we believe the options available meet our riders high demands and ours of course.

We'll set-up the front brake to be operated by the Right Hand lever. Please state in 'Order Notes' how you would like them set-up if otherwise.


Shimano / SRAM / Campagnolo complete groupsets: We've chosen the components to best match the conditions the T640D excels in. Be it climbing in the mountains or racing we have you covered. We only supply complete groupset.

Builds are supplied with 50/34 Compact Chainsets.

Arran's review

On road the T640 has not lost any of the vibration absorbing properties normally associated with titanium, however on the hills when step up out of the saddle on the pedals the bicycle immediately feels so much more solid and stiffer, especially around the bottom bracket
