Lap 11 Bike

donard bikes create a special edition, bespoke, handmade, hand-painted carbon bike for the 11th edition of Lap the Lough

We all like to customise our bikes with a coloured saddle or snazzy piece of bar tape but not many of us can design a bike, create bespoke carbon tubes, dropouts, bottom brackets and bake the whole thing in homemade composite oven. That's what's been happening at Donard Cycles over the summer months. What started off as a casual conversation on twitter between @donardcc @getupbeat @victorychimp and @lovelybicycle quickly spawned the #Lap11bike - a bespoke bicycle project.


Back in June world renowned bike blogger @LovelyBicycle (now relocated to Ireland's North Coast from Boston USA ) - payed a visit to a remote County Down stone cottage to investigate. Underneath the Bangor Blue slates and exposed wooden beams a different type of Irish “black stuff” was brewing. Sheets of raw carbon fibre were laid out ready to be cut and moulded into bespoke tubes and intricate pieces of a very complex jigsaw. Rather than a sterile factory floor she discovered bespoke carbon bikes were an altogether more hands-on, crafted affair.

An alumni of Downland Cycles' frame building school, Owen Byrne started Donard Cycles just over 18 months ago when he began honing his craft with traditional steel frames but carbon was always the goal, "with a Phd in Physics the science involved with carbon always appealed to me." Most carbon builders buy their tubes off the shelf but for the #Lap11bike project project Owen created bespoke tubes to his own specification - all baked in his own composite oven, ”I’ve a PhD in Physics and have developed a new method to analyse superconductor materials so building a composites oven was a fairly simple process.”

“Lap the Lough has always been on my list of things to do, and the event coincided with a milestone in my plans for developing my frames, so I tweeted about building a bike for the event, and designer @VictoryChimp picked it up and suggested painting the bike in the event colours and all really spiralled from there, @getupbeat who organise Lap the Lough are always keen to promote small independent bike businesses and got right behind the project, @lovelybicycle was on the next train down to visit the workshop. - it’s been a whirlwind few months!”

Owen explains the design process and specification for the new bike, “It’s the first bike to use a full in-house tubeset from Donard bikes, allowing the performance of the whole frame to be tuned and gives us full control over the process, which is important from a quality control perspective.”

“I’d describe the geometry as a “fast sportive bike” - it’s broadly the same as a race bike but with a higher head tube. I took all the design data and worked out the stiffness for each tube and how much carbon was required and the orientation the fibres needed to go in. The #lap11bike has three new tubes designs, so there was a lot of testing involved!”


Donard’s tubes are made from carbon pre-soaked in resin. The carbon is taken out of the freezer the night before and allowed to come to room temperature while the workshop gets cleaned down.  The layers of carbon are then cut from templates … ”a bit like a tailors patterns, laid up by hand on the moulds and wrapped in a special tape that compresses the fibres to remove any air gaps - then it’s all into the oven”.

Joints are then reinforced with more carbon strategically wrapped around the joints to make sure the loads aren’t all taken by the adhesive and then the whole frame goes into the oven for the final time to cure the joints, “there is a specific temperature cycle to make sure everything cures properly. This part of the process gives the whole frame it’s final structural strength”.


After a few weeks in the workshop the frame was shipped off to Liquid Colour Design to paint @VictoryChimp’s design then back again to be finished off in Dura Ace.

The bike took just 3 weeks from concept to test ride and can be now be seen displayed in the window of McConvey's Cycles on the Ormeau Rd in Belfast from Monday 22st-Saturday 27th August and en route around Lough Neagh on the 28th August.

So what’s next for Owen and Donard? “We’ll be ramping up production over the next 12 months and we're working on a very special project for 2017”, …we’ll keep you posted!
