What did you do to your EBike this week?

[Powerslider]

I may have to look into that misting fan. Our garage was 92* yesterday and we haven’t even hit the constant triple digit days yet. I realize it won’t be as great as a/c but I’m too “thrifty” to pay the electric to cool the garage.

It’s could have a finer mist like a proper misting system, but you know how dry it is here. It’s not like you’re going to actually be wet unless you’re 3’ away from it. Definitely made wrenching yesterday significantly more comfortable. Recommend, especially when you consider it’s battery powered and portable.

Rebuilt the leaking lever, now ready to go back on the bike for another 7000 miles. Definitely one of the more fiddly jobs I've done, refitting the lever spring took three you tube tutorials & two hours, most of which was spent looking for the spring.

New cassette, chain, pulley wheels and chainring.

Not so much on my own bike but a friend decided to sell his whyte elyte stags work to me for a unreal price, bordering on insane for spec..i got a forbidden druid ecore but ive been having so much fun on this whyte.

Ever since upsizing my Lewis rotors from 200 to 220 front and rear, I’ve been dealing with noisy brakes in the rear. I’m so far down the road of finding a permanent solution, that I’m putting back on the 200mm rear rotor; if only to confirm a baseline.

While I’ve been impressed with the Lewis LH4 brakes, I haven’t been so much with their rotors. I’ll probably try different rotors, but putting back on the 200 rear rotor will be a good test for now.

I will say-when I run the 220 rear rotor I need to use a +20 spacer on the caliper. I can’t help but ponder the caliper spacer factoring into the creation of the resonance (howl). Caliper bolts right to the frame with the 200 rotor.

Saved 35g in unsprung weight.

If it was me, before changing the rear rotor I'd give it a really good clean then try different pads.

Already done.

All I can say is that we have Swissstop Catalyst Pro 220 rotors front and rear now with Swissstop D27 RS pads but previously with Shimano D03S pads, never had any noise issues with either. Only switched to D27 pads because they last longer. I know that's no help to you.

Try a thicker disc, it will vibrate at a different frequency, so it will not respond to the particular set of circumstances that, on your bike, is causing your current disc to vibrate.

Today I changed the two complete drivetrains on our Trek Rails
- Chain
- Cassette
- Front chain ring
- RD jockey wheels


My Trek Rail 9.7 was very overdue : I still had the original chain since purchase fitted, over 2 years ago and 1,300 miles later : when I lined up the old chain against the new chain, it was almost a complete link of stretch difference It explains why shifting was very jumpy


On my sons Rail 5 : Trek did an interesting choice, instead of going for a Microspline hub for his 12 speed, they chose to go with a Shimano HG hub meaning there is only one cassette choice available : a SunRace CSMZ800. This will probably be the only time I'll change the cassette before he outgrows this bike but defo a strange product choice from Trek there!

I took it to a wonderful local bike shop:

and had them give it a full service. I could have done most of the work myself, but I have far too much to do at the moment and with today's temperature hitting 36°C, I wasn't exactly eager to spend hours in the garage.

They trued the wheels (which were rubbing slightly against the fenders), replaced the Kiox mount that had broken in a fall, updated the firmware, changed the brake pads and brake fluid, gave the bike a thorough cleaning, and cleaned the motor.

Now it's a completely different bike: much quieter and smoother to ride.

My wallet is a little different too... €130 lighter.

Installed hope cranks today 155mm

Cut the bars down. Only from 800 to 770 unfortunately, as that was the recommended max chop off...

 

[Kepa]

Yearly inspection for my leased bike, new brake pads and a chain. Normally i do everything myself but this yearly inspection is mandatory. 150€ for parts and labor, luckily it’s included in my “subscription”.

Try a thicker disc, it will vibrate at a different frequency, so it will not respond to the particular set of circumstances that, on your bike, is causing your current disc to vibrate.

I don’t think I can go thicker than the 2.2mm that the Lewis is, but I’m thinking to a different rotor design would also deliver a different resonant frequency.

While changing back to the 200 rotor it looked like the 220 rotor might not have been sitting absolutely flush on the hub. I block sanded the hub surface to make sure the 200 rotor was mated 100%.

Did a quick bed-in around the parking lot, and there was no noise. I’m going to do a quick test ride tomorrow morning at Dreamy Draw/Phoenix Mountain Preserve before work, mostly to test a different suspension setup before I head up to Sedona this weekend. I’ll see if the rear brake stops complaining.
