For 5mm? I would't change anything unless you had removed more spacers recently

Fahgeddaboutit.

For a change that small I think you can make the change and ignore everything else.

A significant change might change how a rider contacts a saddle and require a saddle tilt change or positional adjustment. In some cases, might even create a scenario where the saddle no longer feels comfortable and a different saddle is needed. But for 5 mm (assuming your fit is pretty good already) you're safe.

Interested in this ... :-)

At what point should other changes start to be considered ? Is there a rule of thumb that could be applied based on the position being 'OK' now ?

10mm ? 15mm ?

Any guidance really appreciated.

Cheers,

WD :-)

There's no guideline, really. When a customer asks us if they can raise or lower the cockpit by 5-10 mm, we normally encourage them to go ahead. If they want to go beyond that, we ask them to come in and let us take a look to understand both why they want to make a change and to understand how those changes effect their position.

And of course, they have to tell us how the changes have affected saddle comfort. The line I normally use is "we can tell you with great authority whether you're in a decent position, but we can't tell you with any authority whether that position feels any good. You have to tell us."

Overall, we try our best to get the customer to tell us what they feel, not what they think they need to do to fix it. I can't tell you how many times shoulder and neck discomfort is the result of armpad width, armpad fore-aft position, armpad rotation, or aerobar angle and not the result of how low or high the cockpit is set up.

Not sure that's helpful, but hope it gives you a bit of insight into how I think about it.

OP. It's a bicycle. If it feels fine after the change, done; if not, change. 5mm is almost quite literally 6 hair diameters.
