I’ve had a Turbine 60mm and RF ride and currently have a Haven 55mm and a Syntace megaforce2 50mm. I guess rise should come into the equation?
Out of all of them I think the Haven is my favourite. Light, good looking and was pretty cheap from Merlin. The turbine came from Amazon for less than £40 too to be fair.
Syntace was stupid money off ebay and bought whilst drunk! Took weeks to arrive too. Never had a stem with hex bolt heads as big…Thomson X5 look miniscule in comparison.
Mortop do a load in a range of sizes and colours. The bolts sticking out is a marmite thing though
