Arse over the back wheel – covered!
Drop yer heels – will try
Keep yer wrists down too – my brake/gear levers are at about 45 degrees from floor so I reckon thats enough
Elbows out – never heard this – will try
Knees bent – further suspension?
Let the bike move under you?
Stay relaxed – I think this is where I’m going wrong, I’m too tense and rigid
