absoluteBLACK Spiderless chain ring


What started years ago with the timeless Widget has now become either a craze or passion. Mountain bikers everywhere are ditching their excess chain rings, shifters and front derailleurs. Reasons to do so abound: lower weight, greater simplicity, lower running costs, wider range cassettes and of course fashion.

It was the launch of XX1 by SRAM that really got 1x setups over the line for most riders, with a huge 10-42 range with their massive cassette. The 40 and 42T modifications help bring this to riders who are happily set on a 10 speed setup. I have even seen one used on a 2x setup for extra range.

A dedicated 1x chain ring is essential for success when running a single chain ring. Most manufacturers have adopted a narrow-wide tooth profile, with teeth that are also taller to hold the chain.

Absolute Black are new player in the market, you might have seen their hubs already. Their British designed, Polish made chain rings (and more of their range) are now available in Australia via SCV imports.

We tested one of the spiderless chain ring designs, which they make for SRAM and Cannondale cranks. They also have rings for 64mm and 104mm bolt circles, and oval options too.

The rings are CNC machined from heat treated 7075 aluminium, and the teeth have a tall narrowwide profile for retention. They can be used for a 1x setup on a 9, 10 or 11 speed drivetrain – although a 10 speed chain needs to be used on a 9 speed setup due to the tooth shape. Absolute Black back their chain rings up for a year of excellent chain retention.

The tolerances for fitting on my Cannondale SI SL cranks was spot on, and the offset shape of the ring helps make a great chain line, which isn’t always the case when you make a bike 1x. Best of all, it’s light. I fitted a 34t ring which is 73g. I did this while fitting a new XTR M9000 1x11 drivetrain on my Bianchi Methanol 29 FS. As is always recommended, I used a new chain. The Shimano 11 speed chain mated perfectly, and with plenty of hours on the combination already I haven’t had a dropped chain, or any skipping.

The benefit of the spiderless design is low weight, stiffness, and less parts to loosen off and creak. SRAM have also made spiderless XX1 rings now, but if your cranks have a removable spider, the Absolute Black chain rings might offer a very neat, light, and efficient way to bring your bike into 2015. And they certainly are one of the lightest options out there.

ENVE M50 29" Wheels

Utah based company ENVE have been making drool-worthy carbon components for some years now. Despite the fact that carbon rims are becoming more and more common on mountain bikes these days, you can guarantee that ENVE wheels will be a talking point when someone is eyeing off a steed. Instantly, the big bold logos on each rim scream "fast", "light" and to some extent, "expensive" The kids call this 'bling'.

Canyon Spectral AL 6.0

Round two, and the 6.0 leaps out of the blocks. From the moment we're off the smaller wheeled Spectral wants to go flat out. Standing on the pedals on the small steep climbs is slightly more reactive, surging the Spectral forward that little more eagerly. We need more body language to get the wheels over the roots, but again the 2.4in Mountain King's tread impresses.
