Gradient // Adventure Disc Frameset



The REILLY GRADIENT is an unprecedented engineering achievement. Combining a Hydro-formed REILLY AXIS 3AL-2.5V titanium tube set with our hugely flexible geometry, Mark Reilly designed and all in a package of pure indulgence.

Mark designed the GRADIENT to be very progressive with an ultra-secure disc 12 x 142mm rear thru axle and a stunning but subtle REILLY AXIS multi-facet Hydro-Formed titanium tube set, just like our favourite steel tube set Columbus Spirit HSS

We could have stopped there, but we didn’t. Clearances for 700c 44mm tyres with guards too and 650b 47/50c without guards, flat mount disc and thru axles because we believe Quick Release just doesn’t cut it! The new REILLY AXIS tube set is incredibly stiff but wonderfully comfortable making it ideal for fast gravel riding.

Road, Gravel, Audax, Tour, Cyclo Cross, this bike has it all!

Road CC / David Arthur - Fun and capable adventure road bike with great looks to match the great ride. Read the full 5-star review here.

"The Gradient is right at home negotiating narrow tree-lined singletrack with loose corners and steep climbs and would be a good choice if you're looking for a bike to tackle one of the growing number of gravel events like the Dirty Reiver."

Gritcx / Mark Tearle - Where this bike really excels, in my view, is when you point it downwards. Read the full review here

"I want one. I won’t rest until I get one. I know that if this bike was in my shed that, more often than not, it is the bike I would grab more than any others to take me out on adventures. It’s so versatile, so capable and so damned pretty. This is a bicycle that doesn’t ask, it just insists and, well, who am I refuse?"
