Geometry Information


PLEASE NOTE:  All of our bikes are built to order.  This usually takes between 3-8 working days depending on time of year.

The bike is superb. The build quality is of an excellent quality. Every thing works correctly & the wheel bearings spin like silk. I have never had a bike delivered in such good order. I am so impressed that I have ordered another one for my wife, should arrive Monday. The last time I had dealings with Merlin was in 1997 when you renovated a frame for me, that still is going strong as well! The bad news is Parcelforce. They completely mucked up the delivery time & they said it had been left with a neighbour, my wife found it outside the house at 10.45pm when she came home from work it was a miracle it wasn't stolen. Phone me if you want the details. You get 5 stars Parcelforce 0
Really impressed with this bike. Really comfortable geometry, light as anything, it just zooms up hills with ease, massive contrast to my old bike! very well put together by Merlin and the parcelforce delivery was great. I'd advise to wear gloves if you're riding on rocky/bumpy surfaces as the carbon frame is more rigid than metal so you definitely feel the feedback from the ground a little more. Decent suspension forks and I'm enjoying the remote lockout feature! No issues whatsoever so far.
Very pleased with my purchase, bike was well built by you, well packaged for transport and delivered securely by ParcelForce. Had I known how good this bike is, I'd have bought a second one rather than the bike I purchased elsewhere for my partner some weeks earlier.
Very impressed with the build and quality of the bike for what I paid for. Very excited for a dry day to go for a spin on this amazing bike.
