💬 STAFF REVIEW

It's also perfect for adventure touring styles on MTBs, which are popular overseas.

The neutral geometry and 29er tires handle long distances with ease, making for a comfortable ride.

You don't have to force out creative ways to carry your luggage, as it can be fitted with a rear rack, making large loads a breeze.

Of course, these characteristics make it recommendable not only to hardcore cyclists but also to beginners who tend to stick to city riding.

It even comes with options for a rear fender and a kickstand, making it an excellent wild commuter, too.

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

Rear rack and fender compatible. A versatile 29er hardtail that lets you ride freely in the city or on forest trails.

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

Unlike recent "downhill-focused" MTBs, it adopts a neutral geometry that allows for comfortable climbing, riding, and long distances. Coupled with the high stability and cruising performance of 29x2.35-inch tires, it's an easy-to-handle bike for first-time MTB riders.

In addition, it comes standard with mounts for a rear rack, fenders, and a kickstand. This high practicality, which goes beyond just trails to include commuting, adventure touring, and daily use, is another appealing feature of the KAHUNA.

The main groupset is Shimano DEORE 1x12 speed. The wide range of 10-51T allows you to tackle steep climbs and loaded tours with ease.

This 29er hardtail is highly recommended for anyone from those "who want to start MTB" to those "who want to enjoy various activities with one bike."

The KAHUNA is an exquisite model that, while possessing the excellent off-road capability of an MTB, is also considerably easy to use for daily activities.

It's not as idiosyncratic as recent hardcore MTBs, and it handles climbs and city riding comfortably, allowing for various uses without being restricted to "trail-specific." The cruising performance of the 29er tires is also high, giving the impression that it's less tiring on long rides.

Another significant appeal is the natural integration of racks and fenders, making it a perfect match for "MTB adventure touring" styles often seen abroad. Of course, it's also recommended for urban riders looking for a rugged commuter bike.

I believe this is the perfect bike for those "who want to start MTB but haven't decided on their specific use."

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。
