Join us next Tuesday 10th for an easy going gravel spin after work (emergency miles before the Gravel Extravaganza).
We’ll roll out for a relaxed ride of approx 2 hours. A selection of demo bikes will be available, if you’d like to try one, get in touch this week and we’ll get you set up.
All welcome 🤝
Still earning its keep.
An 80s drill press, a diamond hole saw, and a proven process that’s changed very little over the years.

Cycling Weekly reviews the Sika. The bike had to do the talking. This time, it did.

Delighted to support local club Gravel Extravaganza 2026 right here on our doorstep.
Irish gravel is still in its infancy, but all the ingredients are there. The trails, the scenery and the community. Events like this are what push it forward.
We’ll have the FiftyOne Assassin involved on the day, with a limited number of demo bikes available to ride.
We’ve also limited numbers left of our current Assassin offer at €2999, fully available through the Bike to Work scheme. A bike built exactly for this type of riding.
See you in June!
Many steps go into a custom build. None of them rushed.
Interstellar White Sika
An old friend back in for some paint correction.
Our smallest ever custom frame.
Every FiftyOne starts the same way. Uni-directional prepreg, placed to carry load cleanly through the joint.
Finished with 3K overwraps to consolidate the structure and define the finish. A finish that’s backed for life.
Some of the most important names in this industry
aren’t the ones on the downtube.
This week we learned the sad news that will cease trading.
We started working with them back in 2016, as T47 was emerging.
We wanted a solution that would stand the test of time.
Aluminium introduced the risk of galvanic corrosion.
Titanium didn’t.
Paragon were the only ones willing to machine inserts from solid titanium to meet that requirement.
A titanium jewel, hidden in plain sight,
inside every build.
Godspeed 🫡
