Review: VitalMTB - RaceFace ERA Cranks

VitalMTB has reviewed the Race Face ERA Cranks. Here is what they had to say: 

Carbon cranks have a bit of a spotty track record, at times setting the internet on fire with horror stories and pictures of snapped crankarms. When carbon cranks first appeared in mountain biking, they were by far the lightest options out there, and the early versions probably went too far with the weight savings without having properly validated the longevity and durability of the construction. Riders may also be at least partially to blame for those early durability issues, often seen running the lightest XC cranks they could find in their quest to drop some grams from their enduro or even DH bikes. Race Face has known their fair share of such troubles, and to lay those demons to rest once and for all, they’ve developed the all-new Era cranks. Sporting a number of improvements in the construction, we were keen to see if they would indeed be up for a bit of abuse – read on to find out!

• 52mm Chainline based on a 136mm spindle - can be adjusted to 55mm with Shimano 12-speed Direct Mount Wide ring

• 30mm spindle diameter
• Axle material: 7055 aluminum alloy
• Includes a no-hassle, no-BS Lifetime Warranty - crashes included
• Weight: 426g (175mm crank arm and spindle, verified)
• MSRP: $499.99 USD / $649.99 CAD / 489.00 EUR (includes pedal boots, washers and spindle spacers. Bottom bracket and chain ring sold separately)

When Race Face set out to develop this new crank, they knew they had to improve the integration between the carbon crank arm and the pedal thread inserts. Previous generations of carbon cranks were notorious for failing in this area, so this time around, Race Face went with a much bigger insert that sits much deeper into the carbon. They also took the opportunity to add an external scuff plate, to protect against wear and tear. To liven up your build a bit, there are 7 graphics colors to choose from as well as 8 different colors for the crank arm boots (we went with the low-key silver on black graphics with black boots).

Pulling the Era from the box, the first thing that struck us was the weight – or the lack thereof. At just 426 grams for the crankarms and spindle, the Era is among the very lightest options out there at the moment. It is however still fully certified for enduro riding, and to really show that they stand behind their product, Race Face is offering a “no-hassle, no-BS lifetime warranty” that actually also covers crash damage. That’s pretty solid, and should help alleviate your concerns if any previous experiences with carbon cranks have left a bad taste in your mouth.

The Era is built around a standard 30mm spindle, equipped with the usual preload collar to take up any side-to-side play once the crank is installed. The spindle locks onto the crank arms via a splined interface with a self-extracting spindle bolt, making installation and removal a breeze. To install it, just crank down the spindle bolt (pun fully intended), while removing it is a simple matter of unscrewing the spindle bolt (which in turn pushes the crank arm off the spindle). The chain ring interface is Race Face’s standard cinch job, basically a thin lock ring that secures the chain ring to the crank arm.

Installation of the Era was uneventful, and everything came together as expected. We tested the crank both with Race Face’s own chain ring and an oval ring from absoluteBLACK, with equally good results – they were both easy to install, and they stayed put for the duration of testing. Note that Race Face offers different axle lengths to accommodate all kinds of BB widths, so make sure you pick the right one and also pay attention to the number of spacers specified for your particular build.

The Era feels very solid under the feet, and we also enjoyed the slightly wider Q-factor which gives a little extra stability and provides for a generally quite natural stance. We’ve had the test bike running under two different testers for more than 6 months by now, and although it’s “only” a trail bike, we’ve not gone easy on it. The main tester and author of this review weighs in at around 190 lbs, and while our secondary tester is a bit lighter he rides hard and the bike has seen its fair share of heavy landings and other assorted drama. So far there have been no incidents of any kind – we’ve not had to adjust the preload collar once, and the cinch chain ring interface has not moved either.

We really don’t have anything to point out in this section. Yes, the Era costs $499 USD which is a fair chunk of change to drop on a crank, but it’s fully in line with comparable carbon products on the market – and the Era is one of the lightest, so in terms of grams for your buck, it delivers.

As described in the riding impressions section above, we’ve had two testers on the same test bike for 6 months, and neither of them go easy on their gear, so that all points to a feather in the durability cap for Race Face. The cranks have seen their fair share of rock strikes and such, which have left a few marks here and there. The stainless scuff plates have a couple of dents in them by now, but they remain solidly in place and have not shown any signs of coming loose or anything like that. The exposed carbon has also taken a couple of hits, with some minor surface chipping now visible. None of this seems to have affected the strength or durability of our test sample as this point.
