Having been the victim of a couple off minor offs during my first year of riding (both low side drops - <$300 damage total for both) I have been amazed how small variables can affect our ability to stick to the black stuff. There is the obvious stuff on the road: - Water (aquaplaning due to reduced traction) - Oil on road (especially on corners) - Gravel/Loose stones - Leaves/Other debris - White Lines (esp wet ones) - Tram tracks when parallel (ESP wet ones) - Wildlife (eek) - and more... And of course there are bike related factors. But aside from foreign objects, what are peoples general opinions on the different types of road surfaces and their ability to grip/hold lean angles etc: - Flat, Quiet, Super flat black bitumen (like on resurfaced bit of Eastern FWY in melb - and the F1 track for that matter) - General Black/Greyish bitumem/asphalt like on most roads - Chipseal type roads (After a few months when all the gravel has been swept off) - Grey, Loud, basically stones rolled into asphalt the road. - Concrete - prone to corrugation? (eg vic pde in melb) - Bricks - yuk - SUPER sticky rubber sandpaper stuff (like on 180 degree u turn entrance to eastern freeway off hoddle street) - mmm y favourite - ever put you feet down on that stuff? you cant move them. (might chew up the tires if they laid it all the way along Reefton though) Personally in wet or dry conditions I don't feel that confident on Chipseal roads - even clean bedded-in ones - dunno why.
