Choosing Your Size

The variant name shows column length first, then extension — e.g. L225-E80 means a 225mm column with 80mm extension. Longer columns suit smaller frames where you need more height. If you're converting a vintage MTB to drop bars, L225 is usually the starting point.

Why Nitto

Nitto has been handcrafting bicycle components in Osaka, Japan since 1923. The MT-10 is a piece of cycling history that still makes complete sense today.
