💬 STAFF REVIEW

It's also perfect for adventure touring styles common overseas, where you use an MTB.

The neutral geometry and 29er tires handle long distances well. You won't get tired of pedaling.

You don't have to force yourself to come up with carrying solutions, as a rear rack can be attached, making large loads easy to manage.

Of course, these characteristics make it recommendable not only for hardcore cyclists but also for beginners who tend to use their bikes mainly for city riding.

It even comes with options for a rear fender and side stand, making it an excellent wild commuter as well.

KONA KAHUNA｜The versatile hardtail MTB for city riding and touring

Ride lightly through the city, then head straight to the forest paths. A 29er hardtail that naturally connects daily life with adventure.

The KONA KAHUNA is a versatile hardtail MTB that handles everything from trail riding to city commuting and touring.

Instead of an extreme slack geometry specialized for descents, it features a neutral design that offers a balanced and enjoyable experience for climbing, cruising, and descending. With the high cruising performance and stability of its 29-inch wheels, you can ride comfortably even on long journeys.

Furthermore, it comes standard with mounts for a rear rack, fenders, and a kickstand. Unusually for an MTB, its high practicality, designed for daily use and adventure touring, is also a major appeal.

It is well-equipped with specs that can handle serious trails, including a Shimano DEORE 1x12 speed drivetrain, a BOOST standard front hub, and MAXXIS FOREKASTER 29x2.35 tires.

This highly versatile 29er hardtail is perfect for those who want to enjoy a variety of activities with just one bike.

Unlike recent MTBs that are extremely biased towards descents, it offers a well-balanced performance that handles climbs and long-distance travel naturally. Its 29er cruising performance is also high, making city riding very smooth.

Furthermore, the ability to securely attach racks and fenders is a big draw. It's easy to set up for commuting or touring, making it a great fit for those who anticipate "mostly city riding."

With trail bike performance solidly secured by features like the Shimano DEORE 1x12 speed and BOOST standard, it's a bike you can fully enjoy taking to forest paths and trails on your days off.

MTBデビューに最適なモデル

ハードテールマウンテンで最近多く採用されている下りに特化した「スラックジオメトリ」では無く、登って下って長い距離は走る事が出来る汎用性の高いジオメトリを採用

加え、ハードテールマウンテンでは非常に珍しいキャリアやフェンダー取り付けのボルト台座を配備◎トレイルもしっかり走ってみたいけど、結局街乗り中心になる可能性もあるし、ツーリングにだって挑んでみたい。そんなライダーにピッタリな仕様です。

SHIMANO DEORE（1×12speed）

メインコンポはSHIMANO DEORE（1×12speed）を採用。

10-51Tの超ワイドなスプロケットはトレイルの険しい登りでもバイクパッキングでの峠越えでも強い味方になってくれます。

高剛性＆高耐久な110×15のブースト規格

フロントハブは110×15ブーストとなっており、アグレッシブにトレイルを駆け抜ける事が出来、ロックアウトすればアプローチもパワーロスすること無く登り切れる仕様。

リアは135×10クイック規格となっていますが、これはおそらくツーリング時のトラブルにも対応できる補修パーツの選択肢を広げるため。また、負荷がかかりやすいリアハブをShimano社製を採用してくれているのは嬉しいポイント◎

MAXXI FOREKASTER 29×2.35

ダウンカントリー系タイヤで速さとグリップの落としどころが絶妙なバランス◎ニュートラルなフレームジオメトリにピッタリのチョイス。

オンロードもスイスイ進む巡行性とオフロードのギャップも楽々越える走破性の良いタイヤです。
