Sunrace components – Derailleurs and cassettes

Company Spotlight Pro Reviews

 

Performance:

A quick word on installation of the Sunrace derailleurs and cassettes. Installation is easy. Tolerances are precise. The rear derailleurs in particular were very easy to adjust and had Shimano-level crispness.

Expectations for drivetrains are high in large part because the big players (SRAM, Shimano) have done such a fine job. Consequently it was with muted enthusiasm that I never noticed the Sunrace cassettes and derailleurs after installation because they did their job in the background. Quietly and efficiently.

All worked well in our rides in BC. But BC riding is relatively easy on drivetrains as our mud washes off easily and doesn’t tend to gum up components. I did wonder if the short cage Sunrace RDMX derailleur would handle Whistler bikepark riding as I took my bike on a few end-of-season downhill days subjecting the drivetrain to lots of stutter bumps, sloppy shifts and grinds on rocks. However, I had no issues with shifting.

I advertently stress-tested the Sunrace derailleurs and cassettes when my wife and I were on our Utah roadtrip. We rode the Thunder Mountain trail but first checked whether the trail had dried out by calling ahead. We were (wrongly) told that the trail was “mostly” dry and found ourselves riding through the death-goo that Utah bentonite mud becomes after a rainfall. Words fail to describe how impressed I was at the shifting performance of the Sunrace setups. Both derailleur and cassette were caked in cloying mud that dried to an armoured crust. I could barely clip into pedals. Mud would fly into our faces and coat our glasses then dry to a crust. But the bike kept shifting flawlessly gear-change after gear-change.

 

Overall Impression:

To summarize, I didn’t expect to have much to say other than that the Sunrace kit looks like sharp machined aluminium bling that performs as advertised. However, due to some surprise weather I had the (mis) fortune of testing the Sunrace derailleur and cassette in some of the most extraordinarily trying circumstances to which I’ve ever subjected bike components. The Sunrace components performed flawlessly. After a bit of cleaning with soapy water and a brush they still look gleamingly bling.

Prices for these components from the Sunrace store are as follows :

  • RDMZ derailleur – $ 125
  • Short cage RDMX derailleur – $ 85
  • Ti-Nitride 32t cassette – $ 110
  • Ti-Al 32t cassette – $ 120
