This four-piece set of high-quality Japanese-made Asahi LIGHTOOL open-end spanners is a must-have for the trail or adventure rider. You save about 30 percent in weight. They are made of chrome vanadium forged steel and meet the Japanese Industry Standard (JIS).
These Asahi LIGHTOOL lightweight open-end spanners are a great alternative to the expensive titanium Motion Pro TiProlight combination spanners at a fraction of the price. A clever design of holes and recesses in these chrome vanadium steel spanners reduces the weight significantly without compromising the strength of the spanners.
Lightweight tooling versatility
The weight savings compared to regular steel spanners are about 30 percent. Still, if you compare the weight versus tooling versatility of the Asahi LIGHTOOL versus the Motion Pro spanners, the Asahi LIGHTOOL is the better option because LIGHTOOL spanners offer more tooling versatility for roughly the same weight.
That's because Asahi LIGHTOOL spanners are double-ended in contrast to the titanium Motion Pro combination spanners, which cover only one size bolt head. Each LIGHTOOL spanner works on two different-sized bolt heads.
For example, a Motion Pro set for Euro bikes consists of four spanners; 8, 10, 12, and 13 mm and weigh about 76 grams.
If you add the 14mm combination spanner for Japanese bikes to the Motion Pro Euro bike set, the total weight for five spanners (8, 10, 12, 13, and 14mm) is about 102 grams.
A set of Asahi LIGHTTOOL spanners covers both Euro and Japanese bikes and includes four spanners (5,5 x 7, 8 x 10, 11 x 13, and 12 x 14 mm) and weighs 116 grams.
For about 15 grams more, the four Asahi LIGHTOOL spanners work on eight different bolt head sizes instead of Motion Pro's five. The four Asahi LIGHTOOL spanners are also less bulky to pack.
Sure, if you have an Euro bike, extra spanner sizes such as the 5,5, 11, and 14 mm aren't used often, but they do come in handy at times. The M3 nut on some third-party handlebar kill switches, for example, needs a 5,5 mm spanner. RAM ball mounts U-Bolts come with an 11 mm nut, and if you ride with the Tubliss system, you need a 14mm spanner for the Tubliss rim lock nut.
Asahi LIGHTOOL spanners are forged to the highest standards, are hard chrome plated, and meet the Japanese Industry Standard (JIS). If you prefer combination spanners, we also offer a set of unique and super light Asahi stubby combination spanners.
