I have a tsdz2 that I'm running with an alfine 8 speed rear hub. The cog on the hub is 16T, and I have been, until recently, running a 46T chainring. I damaged that chainring, and looking for a bit more speed, replaced it with a 47T.
I expected that the bike would be a bit faster, but in fact according to the speedometer the top speed is about 3mph slower, and it feels like more work to achieve even that.
What could be going on here? Have I "topped out" the amount of assist the tsdz2 can supply or something? It feels like its giving less assist than it did with the smaller ring, and the speedometer readings seem to support that too. Thx.
