The REILLY GRADIENT is an unprecedented engineering achievement. Combining a hydro-formed REILLY 3AL-2.5V titanium tube set with our hugely flexible geometry, 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 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 x 44mm tyres with guards too, and 650b x 47mm tyres without guards, flat mount disc and thru axles because we believe quick release just doesn’t cut it! The REILLY hydro-formed tube set is incredibly stiff, but wonderfully comfortable, making it ideal for multi-day touring and fast gravel riding.

Road, Gravel, Audax, Tour, Cyclo Cross or Commute, 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?"

ADVNTR CC / James Deane - I could tell the Gradient was going to be a fun bike to ride as soon as I saw it. And I was right. here.

"The Gradient is a thoroughly modern ‘go anywhere’ bike. Equally at home on or off road, it will take you anywhere. And it will do it fast! Progressive geometry means the Gradient is capable running both 700c and 650b wheels. The finished bike exudes a style that makes it look determined yet fast, even when leaning up against a cafe wall."
