As of 1.52, the Crrs for Gravel and Jungle have been altered to increase the rates of speed by consideral margins.
Eric of Insider completed his findings and just published his results here:
A quick overview chart of the Crr changes:
A quick overview chart of his findings for the Jungle:
Now at 4w/kg, where the gravel bikes really chewed into the purpose of the MTBs, which is fine in my opinion, as MTBs haven’t really served a purpose in Zwift (as of yet / if they ever do). While they were I presume designed around the old Repack Ridge, that concept never seemed to take off (which is a shame, single-track routes up up and down Epic mountain would be great fun to escape the roads of Watopia).
But I digress.
Gravel bikes came around, and marked a huge difference on dirt roads, and eventually “gravel” which is just faster dirt, when Scotland was announced.
So here we are, rolling into November 2023, where no bikes, nor wheels have been released on Zwift for an entire year. In years prior, Roval Alpinists were released and produced the same times as the unlockable Meilenstein wheels at a mid-tier level (32?).
What is the purpose of having all of these surface types, if everything is going to fly over them at the same speed? Why have different bike choices at all, if the gaps on Crrs are only going to be closed down?
Let’s consider some other aspects of Gravel and MTBs people have recommended users to try for the past several years:
Up until … now, folks were able to choose slower bikes, or gravel, or MTBs, to stay with groups on group rides or robo partners. As of 1.52 and the Crr changes, this “functionality” is lost, which is a GREAT loss, greater than what the folks at ZHQ I think even considered.
This allowed A riders to join C pace groups on group rides, when being able to hold over 1-1.5w/kg above pace, and continue at the same speed as the group; meaning… the group ride could remain a group ride, and be inclusive for folks well over the capabilities of the ride.
Which now sadly means A riders have nowhere to go for group rides since … there aren’t any A group rides, and rarely B group rides anyways.
Folks that were using these slower frames and bikes, now might not be able to ride with a specific robo partner, without being forced to go back to a faster bike, and now being in a dead space between bots; putting them right back where they didn’t want to be.
Races? ZRL?
Reconning rides and making a tactical choice to swap bikes is no longer a ‘function’ of Zwift racing. With today’s changes, there no longer serves a purpose to swap bikes anymore.
So the joy of reconning a route to decide if it could be worthwhile, is now also a missed element.
These Crr changes are more devastating to the ecosystem of Zwift than I think ZHQ thinks they are.
I want them to reconsider… and at best, return the Crrs to what they were.
Nobody that I know of, wanted to see gravel and MTB bikes to not serve a purpose on Zwift.
They just wanted Jungle to give feedback (resistance), or be skipped (road to sky; paved road access straight to AdZ), etc.
These Crr changes are a massively missed mark by the Zwift team, and a complete misunderstanding of greater functionality.
