2,500 miles, new pads, rotors, and chain :o

[mschwett]

the good news is, my creo rides like new !!! so nice. bad news is, $300 worth of service/parts after only 4 months. the chain probably had another couple hundred miles, as did the front rotors, but it didn’t make sense to bring it back again in a month. the rear pads were totally dead, rear rotor down to 10% or so, front pads at around 30%.

went on a nice ride straight from the shop, put up my best power numbers ever, that new bike feel

Rotors?! Did the rotors get damaged? I understand replacing the brake pads when worn out but how could you wear the rotors that fast?

Congratulations! I bet the health benefits couldn’t be had elsewhere for $300 and as enjoyable?

How does a new chain and brakes give you the best power numbers ever?

Does anyone have the part numbers for the brake pads please.

Mechanically a new chain would certainly be less stretched in both longitudinal and lateral play, and be a lot more efficient.

 

[Dallant]

Even better than new! It’s exciting to know I can take a worn out old 4 month chain and throw it on that worn out old cassette and be the best ever.

Did you do your own inspection and determine the pads were shot or was there some obvious sign like noise (or coasting through a red light (g)) or did the shop notice these issues?

Do you think the brakes were affected by your San Francisco HILLY terrain? I've got hilly terrain here, too.

And as asked, did the rotors need replacement or the pads?

probably just enthusiasm, or possibly i was more rested since they had the bike for 2 days. but the strava power curve was my best effort by about 10 watts for a 2.5 hour effort.

… but that wouldn’t affect the power numbers at the crank, it would affect the speed for a given amount of power!

i brought it in because the rear brakes were making a kind of scratching, ticking sound, speed (not cadence) sensitive, almost constantly. when stopping, they were making a screeching sound and were hard to modulate - more like off or on.

the rear rotor was at the minimum specified thickness of 1.5mm, front was a little better. rear life was probably shortened by having been resurfaced after the pads getting contaminated with some chain lube, but i’m guessing it’s more because of my lack of skill/bravery and the terrain i ride. just about every ride features long descents in which i brake constantly or often to maintain <40mph speeds. i’m sure a more skilled rider would go brake less, use drag to slow down, go faster, and use the front brake more. i’m working on the latter at least, heh. around half my rides also involve a stretch through very dense, wind-driven fog. so although i never ride in the rain, i suppose everything gets wet.

your sarcasm is noted - but i think i made it fairly clear in my initial post. new rotors, new pads, new chain, adjusted RD = “new bike feel.”

the creo power meter is in the crank / part of the motor assembly, so it wasn’t touched and would not be affected by reduced friction in the chain. on the other hand, the bike dropped the chain a few times lately, and had gotten noisy, neither of which are conducive to all out efforts.

the chain was replaced early enough that the cassette is fine. i understand one typically eats 3 or so chains die before a cassette is worn when replaced at the proper time.

I dropped my front chain yesterday with a very loud POP. I thought it was the motor. Climbing a steep hill at lowest gearing and full turbo. But I had put the rear wheel back on the bike in the morning after getting the tire replaced and might have gotten an alignment issue. And I had a heck of a time getting it back on. Or, maybe I've had chain stretch, too. It seemed to behave after that including a few more good hills.

i really hate that feeling! i always imagine it happening when i’m blasting downhill pedaling all out, leading to losing my balance and crashing spectacularly. at least uphill the speeds are low. i thought mine was dropping because of an alignment issue - i had to adjust the RD a bit, presumably from stretch in the wire. but maybe it was also because the chain was worn.
