Long-term Deore crankset review

Rating: Featured Member Review
The Good:

great value! Cranks are light and durable for the price.

The Bad:

The BB will only last a month or 2 if you ride in wet conditions. The crank graphics wear off quickly

Overall Review:

'Brilliant Cranks for an incredible price! but let down by flimsy BB'

This crankset proves that, in a time when bikes from all disciplines and price brackets are coming with all sorts of crazy gearing setups, you can still get a reliable triple crankset for £60!

I've run these cranks for an entire season of XC and enduro racing in the UK as well as some light dirt-jumping,and street riding. They're not currently the most fashionable/popular configuration in the world of 'enduro' but have dealt with rock strikes racing on the Olympic XC course and numerous crashes on my local trails and jumps admirably and are still on my ride 2 years after I bought them.

The cranks themselves are classic shimano components: light, durable and functional. They're nothing incredible to look at but have a classy grey finish not seen on any other cranksets at this price -They can always be blinged up with some ano crank bolts! They are strong and have shrugged off abuse, never causing any problems on the trail. The cranks are also idela for switching to  1x or 2x setup due to their bargain price.The triple chainrings provided shift smoothly though and are showing minimal signs of wear and damage after a whole season. The only drawback about the cranks and rings worth mentioning is that the anodidsing around teh shimano graphics is quite thin and will wear off quickly leaving the raw alloy crank beneath exposed however this is purely aesthetic.

The low-end Hollowtech 2 BB provided however might as well be a disposable unit as is made mostly of plastic and only lasted just under 2 months! It may last longer if you ride in dryer conditions but it's flimsy plastic construction and lack of removable bearings really let it down in the wet conditions of the UK  though and resulted in it wearing extremely quickly. It did however last long enough for me to pick a steel raceface replacement one which wasn't too expensive and was much more durable.

In conclusion this crankset is a great upgrade for an entry-level bike as it offers big weight and money savings, is durable and has potential to be convertd to a 1x or 2x setup, a BB upgrade would be recommended if you ride in wet conditions though!

A solid and reliable but slightly heavy and ugly crankset

The Good:

Reliable, inexpensive, strong

The Bad:

Slightly heavy and ugly

Overall Review:

I've used this crank for over a year and I've had zero issues. Still spins reliably in mostly dry dusty conditions. I've used Many SRAM/truvativ offerings that are pretty much as good, and I marginally prefer the GXP system, but it's close.

Actually I wanted a more bling crank, but I was running out of cash near the end of a build and went for something reasonably priced and well proven, and haven't been disappointed. Originally I set up the crank single speed with a guide, and now with a race face narrow/wide single chain ring, with absolutely no compatibility issues, and a nice weight saving.

Ideally I'd use something like a race face Next, lighter and all bling, but really you only shave at most 200 grams and that 's not a great deal, but it does add up over the build, but cranks are maybe not that critical a component to lighten compared to wheels or forks, but if money is no object, then maybe not the 590s.

money well spent

The Good:

durability, cheap (spare parts too), decent shifting performance

The Bad:

none so far

Overall Review:

Ridden for 4 years, 1-3 times per week, general trail riding, anything from 2 day XC trip to enduro race, all weather condition except dust.
Middle ring changed after 2 years.
Bottom bracket lasted 3 years without any service (stupid), swapped for new one for 7$.
Considering buying again - new deore m615 double crankset in black - which IMO looks great.
Good for anything but straight gravity riding.
For this price I don't think there is crankset which comes close in performance on current market.
