The winger, whose try in the closing stages of last yearâ€™s World Cup final in Japan sealed success against England, will likely have a difficult choice in 2021 when the re-arranged Tokyo Games clash with the Lions tour of South Africa.
Kolbe, 26, would stand a strong chance of selection for the South African 'Blitzbokke' -- the rugby sevens side which will be among the gold medal favourites in Japan.
He had previously said he would like to be selected but now that there is a date clash he has made clear his preference.
â€œItâ€™s a tough decision but I would definitely choose taking on the British and Irish Lions,â€ he told the website Planet Rugby in an interview.
â€œAlthough I would love to play sevens for my country at the Tokyo Olympics, to be part of a Lions series is a goal I really want to achieve and I would like to be a part of that because it only happens every 12 years.
â€œNext year would be my only chance to face them, if I do get selected (for the Springboks), as I wonâ€™t be around for their next tour so I would definitely go for that option,â€ he said.
