Is there ever a line where the price to weight loss ratio is too much for the wallet to handle? I’m just throwing this out there for the weight weenies to chime in on and if you think “just lose some weight from the engine” instead… well I hear ya already!
I came across a company called Scrub Components that does rotors for disc brakes. Their rotors are pretty cool looking and their weights are really good. A 160mm 6-bolt rotor comes in at whopping 52 grams. Very impressive to say the least. Also impressive is the price: $145 for ONE rotor without bolts. Putting matching 160mm rotors on a bike cost $290! That doesn’t count the cost to switch to organic or resin pads which are a “must”. Add those in, but re-use your existing bolts and your total cost comes out to $334 before shipping.
Alligator Serration Disc rotor
Compare that to Alligator Serration rotors. The 160mm version weighs a decent 92 grams, not portly by any means but no where near as light as the Scrub counterparts. The price, though, is where it shines: $12.98 per rotor via pricepoint.com. Although forty grams heavier than the Scrub Component rotors, the Alligators are less than 1/11 the price.
If you’re doing the math, each gram you save upgrading from the Alligators to the Scrubs cost $3.85. Not too shabby when I put it that way, but multiply that by the 80 grams you save and it comes out to an extra $308 before shipping. Is the 80 gram weight loss really worth the extra money?
By the way I’m not picking on Scrub Components. They’re made in the USA and their users seem to like them. I’m only considering the weight and cost aspects of these components. For all I know Scrub rotors could be the best ever and Alligators could be so bad I wouldn’t put them on a bike thief’s ride.
