I was going to upgrade my bike (Decathlon Triban 100) and ordered the whole new groupset (Shimano SORA). It will be delivered soon, so my question is how hard is the replacing process? It is not a problem to pay in local bike service for the replacement but I’m also interested in trying by myself. I have a repairment kit and all the things, I like to make some maintenance of bike by mysleft but I didn’t do so complex maintenance before.
Are you also getting new rear wheels? The 7 speed hub is probably not wide enough for anything other than 7 speed. You might need a new rear wheel.
Does the sora have a front derailleur? Are there suitable mounts for it on the frame? (As the triban does not have a front derailleur).
If you made sure everything is compatible, it can be done, even by beginners. Just calculate extra time for watching YouTube vids 8-)
I bought all the things exactly like in this post on Refdit. So, it should work without changing a wheel and also I ordered front derailleur of “B” (Band-Type) series that is suitable for mounting without special mount. I hope it will fit, otherwise it will be a huge waste of money (about a half of the new Triban 100 price).
Triban 100 is a nice bike for it’s price and I had a lot of good time with it. But after my last trip to one of National Parks with small-scale mountains (about 1000-1500 meters above the sea) I realized that it is very hard to go up with 44/28 lowest gear. Maybe bying the whole new bike will be easier but I already named my Triban 100 and also I do not like to buy new thing and produce waste when I can upgrade existing one. With Sora I will have 34/34 and it should cover elevations up to 20% that is enough for the most of beautiful places around me.
Ok, sounds good then. A 34:34 will be a big upgrade over the current setup
