Mr Brazier graduated in physics and qualified as a chartered accountant specialising in tech start-ups before launching a pioneering internet finance agency in 1997.
He went on to become CEO of hospitality giant Dolphin Square before joining Richmond-based corporate software firm BookingTek as chief finance officer.
Club colleagues paid tribute to a “safe, conscientious and powerful” cyclist who had raised thousands of pounds for children’s and cancer charities in sponsored challenges in the UK and overseas.
He joined the Twickenham club last month, having been a long-time member of amateur club Dittons Velo (DV) with whom he had spent the previous weekend on a cycle break to Majorca.
David Marsden, 46, who was with Mr Brazier on the Majorca trip, told the Standard: “Everybody is extremely upset and wants to understand what has happened and why.
“He was a well-loved friend of the club, an enthusiastic cyclist and he will be deeply missed. He was such a lovely man.
“He was a strong, safe and competent cyclist. He was an inspiration to the younger guys of what they would love to be like when they got into their fifties.
A complaint made about the pothole in 2009
“Our thoughts are with Karen and the boys and all of his extended family. We love him and miss him.”
The South East Coast Ambulance Service were called to the junction of Weybridge Road and Weystone Road following the accident at just before 8pm on Tuesday.
Surrey Police and the Health and Safety Executive have launched an investigation into the crash.
A TCC team vest was attached to a low wooden railing at the scene of the crash, where a number of floral bouquets have been placed in Mr Brazier’s memory.
One note read: “No words can possibly provide any comfort to the poor family at this distressing time.
“It’s an utter tragedy and a hopeless waste of a precious life. His family and friends must be devastated.”
Harry Turner, 81, who lives opposite the scene, said the pothole was “like a ditch”.
He added: “The road just there is full of potholes. They did a temporary job last year but if you don’t do it properly, once you get a frost water freezes, expands, and holes appear again.
“It is dangerous, it’s a fast road and the main road out of Weybridge.”
Surrey County Council confirmed it is responsible for repairs to the stretch of road and said the pothole would have been filled in when it was resurfaced in the winter of 2014.
Tributes from colleagues and fellow club members posted on social media describe Mr Brazier as a devoted father, loving husband and an “out-of-this-world” cyclist.
Fellow DV member Jaime Dunster, a director at Savills estate agents, said: “He cycled on a different planet to me but was always hospitable and kind, with a smile or laugh close by. He epitomised DV to me when I was a newbie. Thoughts and prayers with all close to him.”
Brett Scillitoe, a DV member from West Molesey, wrote: “For now we focus on Karen and the boys. Once we have said goodbye to Ralph, we plan and make sure that this never happens again in Surrey.
“We owe it to the Braziers and to ourselves. This could have been any one of us. I will not let this rest. But now is a time to mourn and celebrate one hell of a guy and a great climber.”
A SECAmb spokesman said: “A man had come off his bicycle - possibly due to a medical event - and gone into cardiac arrest.
“Despite advanced life support being administered by the ambulance crews, the man was later declared deceased.”
Figures released last week revealed the Surrey County Council paid out almost £376,000 in compensation for 1,302 incidents of damage caused by potholes since the start of 2013.
A council spokesman said: “Our thoughts are with the family and friends at this difficult time and it’s important we wait for the conclusion of an investigation which will explore what happened.”
Anyone who witnessed the incident is asked to contact Surrey Police quoting reference P16047500.
