He describes it as the best day of his life so far.
Donning the red, white and blue bands and joining a prestigious list of former champions will forever be a treasured memory.
It is a moment the Canyon Eisberg recruit will reflect on with great pride and satisfaction as time ticks on.
But Louis Rose-Davies knows the British junior road race title he clinched in Wallingford last July will not give him a head start as a first-year senior.
The 18-year-old, from Chertsey, is under no illusions. There are no shortcuts, no free rides and no inch given in the professional peloton.
A product of the Hillingdon Slipsteamers club, Rose-Davies is now prepared to start afresh and determined to make a name for himself at the top table. He said:
“Winning the British title was the best day of my life so far. It is still a bit of a shock. I go into every race and give 100 per cent but that day everything went to plan.
“In my head I had a game plan of what I wanted to do. And that seemed to flow perfectly through the race.
“Now I’m an adult, I have put that behind me a little bit. It is cool to say I was the junior national champion, that will always be something to reflect on.
“But at the moment I have to focus on what is in front of me rather than looking back. I want to make my own name in adult racing.
“It was nice to look online and see what names have won the junior national champs. There are lots of pros there. That gives me confidence I’m on track.”
Rose-Davies, who will make his Canyon Eisberg debut at the Perfs Pedal in Portsmouth on Sunday, edged out Tom Pidcock to win the British crown.
Former winners of the national jersey include World Tour stars such as Chris Lawless, Peter Kennaugh, Dan Martin and Steve Cummings.
Rose-Davies spoke of his desire to race at the highest level when he penned his deal with Tim Elverson’s squad last summer.
After cutting last season short because of injury, he enjoyed a leg-stretcher in the Hillingdon Winter Series last Saturday – completing a one-two with team-mate Alex Paton.
Now both riders are relishing the chance to line up for their new team in the Perfs Pedal before the first UCI battles beckon in March. Rose-Davies added:
“For me, this winter has been particularly long. I hurt my knee before the Junior Tour of Wales in August and called my season off early.
“So the winter has dragged. It feels like it has gone on for ages. It was nice to be back racing at Hillingdon last weekend and I’m really looking forward to Sunday.
“This winter has been a big step up. I trained a lot with Rory (Townsend) last winter, so I’m used to the longer rides.
“But it is more consistently hard now. I like that kind of training, though. I like an almost old-school approach, with all the big miles.
“My dad always says winter miles, summer smiles, so fingers crossed that will be the case this season.”
