[product technical analysis]
Gossamer is a high-end sprocket for the aluminum alloy enthusiasts. It has a history in the Paris-Roubaix battlefield and does not need to be rumored.
But the details can not be ignored, not only because of its new smooth integration design, the forged aluminum handle is heavily fanned in order to achieve a good strength-to-weight ratio, and the Gossamer crank is impressive. Lightweight, only 751 grams.
The universal BB368 axle is forged from a stronger alloy. This 30mm axle is compatible with the English Threaded 丶 SMN Press Fit and the bottom bracket of the BB30 with just a few spacers.
The sprocket wheel is made of even more tough 7075 aluminum alloy from a computer lathe. It is specially designed for the fastest and precise shifting. The bolts of the sprocket wheel are extraordinarily strong and chrome molybdenum steel.
More hardness is our ABS asymmetric screw spacing system. The fifth bolt is hidden under the crank arm on the drive side, providing strength where it is most needed, providing resistance when vigorously stepping on, and allowing the shift to be exceptionally crisp. The Gossamer has four crank lengths and five shifting options. It can be used as a glove fit to match any combination of cycling and rider styles.
It can also be used with the optimized chain center line for 135MM O.L.D. disc brakes.



















Expert Review

Review by: Ken D.
As for me, a lengthy and meticulous primary product research is a necessary move before buying anything online. Impulse shopping is as much fun as risk, so I thought it was worth spending some time to take a look at the product attentively.

It’s safe to say I was immensely fortunate to stumble upon the S59 Bicycle Crank & Chainwheel BB30 shaft core CNC hollow disc brake road bike sprocket crank length 170/172.5/175mm 34-50T so conveniently available here. My market research has helped me understand that this product is not like the large majority of the seemingly alike items courtesy of its superior quality. I’ve digged out some basic requirements that are commonly applied to the products of this type, and learned that the one I’ve purchased distinguished itself from the rest and apparently is more than asuitable alternative for this price category.

I could wish for a lower cost, and who wouldn’t, (the one that is much closer to zero, how cool would be that?), but, to be honest, the current price is really fair. You shouldn’t expect a superior quality item to be unbelievably uncostly as it will mean either a poor quality of raw stock, or a second-rate production quality, or both. Or, even more repulsive, it will mean cashing in on ordinary workmen. No thanks, not the right kind of item I agree to encourage with my acquisition.

I would also like to add that when I got my acquisition delivered and opened the package I was moved to see that S59 Bicycle Crank & Chainwheel BB30 shaft core CNC hollow disc brake road bike sprocket crank length 170/172.5/175mm 34-50T has arrived in astonishing working condition, with no downsides or physical defects or stuff like that. It’s adorable to know the buy has proven its value, so yeah, I surely recommend obtaining this one.
