Thanks for the insight fooferdoggie. The Civante has the new Tiagra calipers (BR-4770) that came out last year with the hydraulic levers with trickle down tech from the 105’s and it has the 105 rotors (SM-RT70). These work great with the metal (L04C) pads. I am surprised just how precise the...

I kept reading about the noise from many online forums but it’s not noticeable. My riding group couldn’t tell I had gone from the resin (L03a) to the metal (L04C). I installed them myself and that was the first time I’d ever done any bike job on any bike. Lol. I also know that metal brake pads...

Also, if you ride fast down hills, I don’t know about you but I never felt that safe with the braking power on the resin pads (L03A). So, I replaced them with the metal pads (L04C) and the stopping power is again 2x better. I feel in control of the bike’s braking capability now. I hope this helps.

thanks. I also found out it would be a good idea to replace my chain after just 1,000 miles in order to save wear and tear on the cassette. So, I bought Shimano’s ebike chain CN-E6090-10. And wow, the shifting on the bike is 2x better than on the KMC chain that came with the bike. On the KMC...

Do you need to do anything special to use the Wahoo/Garmin quarter turn as a Stem Cap? I see two screws but the stem only has once screw in the middle. I bought a Kamoo 2 today so I hope your solution works!!! The pic is of the Kamoo 2 mounting on the back

I have a question about the new Tiagra 4720 groupset. The 4720s use the BR-4700 calipers which use the same Shimano brake pad (L04C) and hose kit (SM-BH90-JK-SSR) used by the current 105 R7020, Ultegra R8020, and Dura-Ace 9120 groupset. Additionally, the 4720 hydraulic levers use the same cable...

Where does the white Apple cable go to? I don’t see it connected to the phone.

Wow, that’s perfect!!

Because the Civante has the SM-RT70 Shimano rotor (used in the 105 group set), we can use the L03A resin brake pad or the L04C metal pad inteded for the 105 to Dura-Ace group. All new Civantes come with the L03A resin brake pad installed. So, if you'd like more braking power, you can try the...

The Civante has a nice upgrade from the other Yamaha bikes. The Civante has the disk brake rotors (SM-RT70) used by the Shimano 105 7000 series with ICE TECHNOLOGIES to "significantly reduce heat build-up in the brake system to ensure consistent high performance braking even on the steepest...

Ah ok. I’m new to cycling so I appreciate your insights... THANKS

Wow, you’re a wealth of information jabberwocky... THANK YOU. Do you know if this power meter would work? https://shop.4iiii.com/products/left-side-precision-powermeter-ride-ready?variant=12217360547919

Yamaha says the motor’s software was tuned to be used by a 10-speed cassette. I know Giant’s software is tuned to be used by an 11-speed. But Giant uses the more powerful PWX-2 Yamaha motor. I know more gears help us use less watts bc we can peddle at higher cadences which makes climbs easier...

I use all of my gears so I don’t think that will work for me but thanks for the info.

The 105 is 11-25. Ours is 11-32T. Will this work?

Since the Yamaha/Giant cranksets seem to be a motor-specific propriety part, I’m not eager to upgrade it. I don’t think off the shelf Shimano/SRAMS were made for powerful ebikes. Especially not for our 28mph/70+ nm of torque Yamaha bikes. With time, I’m sure others will try it. I’ll let them be...

The 105s are now only made in 11-speed. So you’d have to get the ?6-yr? Old 105s. Whichever older model Shimano made in the 10-speed for both the cassette and rear derailleur. You definitely can’t use the Ultegra cassette because those aren’t available in 10-speed. Let me know if you find a...

Yeah, I think the crankset is proprietary??? Or it uses a specific shape for the motor. But I am interested in upgrading to 105s so keep me posted. Also, I’ve read that the Ultegra front derailleurs are compatible with the Tiagra group set. I’m looking into this. I was having a hard time...

I went to my LBS. He looked up the DT Swiss HE 1800 wheels. He said since Yamaha uses standard Hub components (12x100 front and 12x142 rear) he can just pop out DT Swiss’ flange and put in Yamaha’s so the lock fits in there for the magnet. But I didn’t get them because I don’t want to risk...
