One presumes a longer ahead tensioning bolt and a cap under the fork crown is the failsafe.
Its a 20mm bolt. Just looked at mine and it looks like there is a hole on the underside of the fork crown, but couldnt get a good look without taking the wheel and mudguard off. It would be completely bizarre if they had actually engineered a failsafe into the forks, putting a hole in the crown and threading the lower section of the steerer – almost like they were expecting it to happen?!
What is the failsafe Islabikes are providing?
For bikes that allow it, Islabikes are supplying a retaining bolt which will act as a failsafe in the unlikely event that the bonding between the steerer and crown fails.
This can be ordered via the Islabikes website free of charge. The packet will include a 20mm stainless steel bolt with thread lock applied, a washer, an Allen key, and instructions. It’s a case of removing the existing bolt and replacing it as per the instructions.
They will start distributing these fail safes on Monday 27th June 2022, and once fitted a bike will be safe to ride.
