Took the Propel to a highly rated bike mechanic - CycleServe, Bramcote, Nottingham.
Due to social distancing I couldn't get too close but, John asked me to hang about incase its something he can sort quickly. There was a problem between the STI and Front Mech. However, John, tinkered with the cable at both the barrel adjust which was initially stuck and also tinkered with the cable where it meets the front mech. 10 minutes later he got it shifting onto the big ring.
Then after a test ride I returned stating I can't get it onto the big ring. John took it out for a spin and said its spot on, which, I could see and hear myself as he went past. I had a go, to no avail. John identified that in addition to the cable, I was not using the STI lever correctly and catching the secondary lever, sending mixed messages to the mech.
To soften the embarrassment, John did state I did an awesome job of indexing and balancing the brakes.
John at Cycleserve also made me feel welcome, was happy to advise on upgrades I had brewing in my head as well as give me a few tips on shifting (certain crank positions etc), parking the bike up, best practises which are only gained through experience. A truly rare experience to meet such an ethical and skilled person like this in, this day and age!
He also sorted a few other bikes on the spot that looked like they had reached their end of life sending the riders off with big smiles.
