Would appreciate a bit of feedback on a custom frame I'm considering getting fabricated, just to make sure I'm not trying to do something which is impossible
The bike is going to be my ultimate commuting machine, consisting of the following:
- Ti frame
- eccentric bottom bracket
- Di2 Afine
- belt drive
- dynamo hub lights
- 700cc 28mm tyres
- full mudguards
- hydraulic disc brakes
- drop bars
Getting all of those in one package isn't exactly an off-the-shelf purchase, so I'm most likely having a frame custom made. I have already got hold of a cheap Charge Mixer frame which fulfills most of the frame requirements, but I'll still have to cut the dropout to fit the belt. Considering having a ti frame made in China, and was contemplating exactly what I want.
Since fitting Di2 to my road and tri bikes, I love having everything internal, so I'd like to do the same for my wiring and hoses on my new frame. Adding an eccentric bottom bracket complicates things somewhat as you can't really route anything through the BB shell, and as I'm going for Ti, it's not as if there will be any big voids like you would have with a carbon frame. As such, I'm contemplating the viability of adding some tubular gussets around the BB shell to accommodate hoses and wiring. Quick solid model screenshots below:
There will be a Di2 battery in the seatpost, wiring going forwards to the cockpit for the shifter, and then back inside the chainstay to the Afine mech. Also running up the seatpost will be wiring for a rear light, and inside the down-tube and non-drive chainstay will be a hydraulic brake hose.
I appreciate that it'll cost extra to have the gussets and access holes fitted, and it'll be rather fiddly to get it all fitted, but hopefully it'll be worth it for a nice clean look. Another consideration is potentially the distortion of the BB shell as the eccentric clamp is tightened.
Anyone see any issues with this? Any feedback appreciated.
