Lol tell me bout it, but have found if you put a Beenie hat inside first then put the helmet on no whistle sometimes you might have to pull the helmet down and a little wiggle hey presto just the wind noise lol but better then that high pitch noise.
ooohh?? Top tip will give it a go, just been out this evening and it even though its getting warmer weather wise its worth it if it does the job. Will see if it helps this weekend. Cheers
Wait til you get the track bug and head to Cadwell, you'll need too beanies to see up the mountain lol
