The club thus completed the triple crown of British Team Championship, plus the South West Division 1 and Premier League titles.
Hammers achieved the win without their Polish riders.

However, a gate exclusion for Mike Morgans brought the home side briefly into it.
Then three 6-4s and two 7-3s put Horspath 16 points ahead at halfway and they never looked back.
Mark Carmichael gave strong support with solid scoring throughout the order.
