For tweaking your handlebar height this selection of spacers is ideal, allowing you to combine spacers in different ways to get things just the way you want them. I can't think of any way in which this collection could be better.

Bought to replace a selection of different makes/diameter spacers fitted by dealer. Installed while fitting new adjustable stem, tidied everything up particularly 48mm one replacing 5x10mm. Well made.

Nice solid spacer set, which includes some longer spacers than you normally get in a typical set. Ideal for a Nomad frame with a long exposed steerer. Everything fitted well.

Glad I bought this set not individual spacers - gave me the flexibility to mix and match to get the spacing just right

What can I say, these are headset spacers.
The variety of sizes is very useful for when you want to fine tune stem height or add something like an accessory bar into an existing setup.
