Are Shimano Sora shifters good?
The big differences between more expensive options and the Sora are the non-changing 9-speed (the number of gears available), and the additional weight compared to more premium versions. However, Sora maintains its reputation as a reliable groupset offering good performance.
Is Shimano Sora compatible cassettes?
Sora only comes with a choice of nine available speeds at the back — you can only use it conjunction with cassettes featuring nine sprockets — compared with the 11 found on Dura-Ace, Ultegra or 105, or the 10 speeds found on Tiagra. However, nine speeds are still more than you’d find on Tourney or Claris.
Is Shimano Claris better than Sora?
The Sora groupset does indeed sit above Claris in the Shimano pantheon. Shimano carefully engineers each level to be incrementally better than the one below it, in terms of features, weight and quality of materials. You should be able to feel a difference between the two groupsets in terms of shifting.
Can you use Tiagra shifters with Sora?
If all you want is the Tiagra shifter with your existing group set, then I think a Tiagra 9 speed shifter should work with your existing 9 speed Sora setup. There’s a few Tiagra 9 speed/triple shifters available on eBay, it seems.
Is it worth upgrading from Claris to 105?
Overall most people will not make a jump from Claris to 105 because the costs usually end up being almost the same price as 50% or more of the value of the bike. Now 105 to Ultegra/Dura-Ace is more common and cost effective (e.g. As I wear out components in the drivetrain I am replacing them to Ultegra).
Is 105 worth it over tiagra?
If you want really low gears, 105 is the better choice. Tiagra offers excellent value for money but 105 is certainly the better groupset and we’d recommend going for it if your funds allow because of the better brakes, the small weight saving and the upgrade to 11-speed.
