    4720 Tiagra hydraulic levers have the same cable pull ratio as current Dura-Ace, Ultegra and 105

    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...

    Civante disk brakes are Shimano 105 SM-RT70

    To use Rouvy, TrainingPeaks, RGT only cost me $100 in bike equipment

    I didn’t know the cost savings of owning an ebike. I just found out that because ebikes have Speed, Cadence and Torque sensors all I need to participate in online training/racing/cycing is an indoor Bike Trainer Stand, which I bought for $75 at Costco. I also needed to buy a 12mm rear thru axle...

    Rouvy, Wahoo, Zwift, RTG Cycling, Bluetooth apps for Display X

    I found six apps that recognize the Yamaha Bike’s Dislpay X: Wahoo, Zwift, Rouvy, Ride GPS, RGT Cycling and Komoot. Now, that doesn’t mean it works very well with all of them. It worked perfectly on Wahoo and Zwift. Wahoo displays Cadence, Speed, Climbing and Distance. ON APPLE TV Rouvy and...

    Does Bosch, Brose and Shimano plan on making their own branded eBikes

    I‘m new to the bicycle community. I’ve learned a couple of things (I think). The three biggest bicycle manufacturing companies (by revenue) are Giant, Trek and Merida. Giant not only makes the frames for themselves but also for Pinarello, Colnago and Canyon (to name a few). Trek manufactures...

    NEW 2021 MOTOR COLLECTION (PW-X2 45) for the CIVANTE?

    I found Yamaha’s website displaying the 2021 Model Year Collection. I know the CE was launched August 2020. The PW-X2 and the ST in July 2019. And the TE in June 2018. The only motor (that I know of) being sold in the USA is the PW-X2 to Haibike and Giant. And, it is found in Yamaha’s YDX-Moro...
