Hey Folks,

I'm looking at getting a new frame and obviously I'd like to get the set-up as close to my current bike as possible.
The problem is I'm having a hard time choosing the right size. I'm torn between two sizes.
If I decide to go with the smaller size, the reach would be 4mm shorter than my current ride and the stack height 1.5mm higher. If I went with the bigger size the reach would be 1mm longer but the stack would be 17.5mm higher.
I'm leaning more towards the smaller size and maybe adding a longer stem but some extra input from you guys would be appreciated.

Thanks

Reach. By which I mean the smaller size. Imo, reach is the most important dimension, having been put, over and over on 54s, based on my height, when due to my short torso, I needed a 52.

In general, Lengthening a stem is less likely to impact handling negatively. Ymmv, but that's my experience.

Are you sure about those numbers? Only 5 mm change in reach between the sizes, but 16 mm change in stack?

My feeling is, 5 mm change in reach is nothing much, easily compensated with a different stem. 16 mm change in stack could matter more, if you're trying to slam the stem (position the stem as low as possible).

Yep prety sure those numbers are correct.
Anyway, this is the geometry chart and I'm torn between the 52 en 54. My current set-up is stack: 534.5mm (so 2.5mm and 18.5mm differenece instead of the reported 1.5mm and 17.5mm) and reach: 388.
