Groupsets are a starting point for selecting parts from a series.
At each link, you can select shifters, derailleurs, cassettes, and other parts individually. These are not necessarily packaged sets containing everything. Check the rear speed, front configuration, freehub, and brake system before choosing.

INDEX OR FRICTION?

Choose a "click" or set it by feel.

Index

A system that pulls a set amount of cable with each lever click. You select the gear position based on the compatible derailleur and speed combination.

Friction

A system where you set the shifting position by moving the lever rather than relying on click positions. Some models offer both, but it is not available on all products.

Even friction shifting has limitations, such as cable pull and derailleur travel. This does not mean it can be used with any derailleur.

SMALL PARTS, BIG POSSIBILITIES

Freedom of assembly,
starting with small parts.

Shifters for 8-speed internal hubs, mounting hardware, and replacement parts. Whether you want to replace only the shift lever or keep riding with a different handlebar, you can find the options you need.

Mounts differ for road, MTB, and other applications. Please check compatibility with the shifter body before choosing.

BEFORE YOU BUY

If you're unsure, check here.

Can I use any 10-speed shifter?

No. Compatible shifters differ between conventional SHIMANO 10-speed road (105 5700 series / Tiagra 4600 series), Tiagra 4700 / GRX 10-speed, and SHIMANO MTB. Please choose based on the rear derailleur model number.

Are ADVENT and ADVENT X the same?

Do not assume they are the same; check the compatibility specifications for each product. Here, we distinguish between ADVENT 9-speed and SWORD / ADVENT X. You also need to distinguish them from SHIMANO-compatible models.

How do I choose between a right-only shifter and a left-right set?

If you only need to operate the rear shifting, a right-only shifter is an option. If you also need to operate the front shifting, consider a left-right set. Please also check the front speed and derailleur compatibility.

Can W levers and bar-end shifters be installed directly?

For W levers, you need to check the frame mount and installation parts. For bar-end shifters, check the handlebar inner diameter and mounting method. For thumb shifters, please check the clamp diameter. If you are changing the installation location, also check the mount specifications.
