Sizing for the ATR – 5’11” riding a 54cm CdF but could go up a wee bit in siz
I have a 54 croix de fer and have just switched everything over to a 54 tripster.
The tripster is about 8mm taller in the head tube if you use their supplied FSA headset. I ran two 10mm spacers on the croix and only one on the tripster.
With the same kit the tripster is about exactly the same fit, based on where my knee is over the pedal and how I can see the hub compared to the bars.
The tripster steers a lot slower – it is more of a cruiser, so maybe the 57 with a 30mm shorter stem might work well, as I think Dom from Kinesis mentioned that it is supposed to have a shorter stem.
But standover will be less, obviously.
Where abouts are you – is there someone local whose you could try ?
