I used to have a couple of BMXs - it was the big thing when I was growing up. If you had a Grifter or a Chopper in the early eighties you felt a twat. Andy Ruffell was my hero from about 8 onwards.
Mechanical gears are fit and forget? In my experience they always need indexing and rub at extremes. Di2 has 16 micro adjustments each way for every gear. No noise and you can do it on the fly. And the front mech trims automatically and moves with a push even under hard pedalling. I'd never go back and it's only those who haven't used it that knock it. It's superb. And a charge lasts weeks. The new stuff even has buttons under the top to change your garmin screen. It's now on my summer and winter bike.
I ride a Ribble Sportive with Tiagra. Do plenty of miles to help with knackered knee and its been fantastic. I've never bought into the cycling equipment hype, although have spent far too much money on cricket gear in my lifetime! None of which ever got used to it's optimum performance ...
Tall bike Bobby's just ridden about a thousand miles down America. He swears by his set up for balance. I wouldn't mind trying it. please log in to view this image A it more on him.
Ribble offer terrific value for money. I must have kept them afloat in the early 90s as I lived 50 yards from their bike shop in Preston Lancs.
I think I'm old school! I can adjust manual gears in a nano second. I like the simplicity of mechanical stuff. One of my relatives does triathlons and iron man races - he had di2 fitted to his newest bike and he's had nothing but bother with the whole set up. I seldom have the gearing at extremes, it's in built not to torture the chain by running it diagonally
Indexing, battery discharge time all sorts. He lives abroad too, so getting the issue resolved was problematic. No one would take ownership of the issue and it took over 4 months to get the problem resolved. I'm sure the bike was a Felt IA2 di2 - something like that.
did he download it from a Kodi Firestick X17689 Beast 3D streaming printer ? (Even bloody bike names are confusing nowadays.!)
Bell comes as standard, though at that price they might include an air horn. I remember one of thos electric sirens I got for my bike (pre bmx) that made a police car/ambulance/fire engine sound - mega. This should be a key component for any £10k bike.
I loved my redline BMX back in the 80s would never trust mags tho , and I broke a few bones but never my bike
