I have a Giant SCR 3 which was a freebie from a mate, who had it new. It's approx a 2006 I think, and I've had it about 5 years. I've spend a relatively small amount along the way at the LBS, keeping it going.
Due the serious mileage it's seen between the two of us, the following are now clear;
- The original Tiagra 9x3 groupset is nearing End Of Life (confirmed by friendly LBS, who don't try to sell me anything I don't need)
- The original Alex rims are WAY beyond the wear indicators, although, nothing bad has happened yet!
- Braking is now a serious effort on the hands (needs new cables I guess)
As much out of nostalgia for my first decent road bike, I'm tempted to give it a new lease of life. I have other bikes, but this is/was my go-to commuter, and old enough to lock up in town on a night out too.
I believe the 9 speed is now obsolete in Tiagra? So do I go Sora 9 speed (Sora in 2019 perhaps similar standard to 2006 Tiagra?) OR, as I need to change wheels too, is this an opportunity to go to new 11 speed Tiagra?
Am I missing a trick here? Can I just by new cassette, chain-rings, chain, and keep it going...
PS: Little bike DIY experience to date, although I am mechanically minded.
