Hey all, just started my 2nd month of TR. Using a combination of Jetblack Z1 and Cycleops Aluminium Rollers with Garmin Speed sensor. My initial ramp test (Z1) gave me an FTP of ~239 when I had cyclocross tyres on. A month later I changed to Maxxiss Refuse tyres so redid my Ramp test and came back with an FTP of 323 this time. I followed the test with a Taku, with a normalised power of 201 and an average HR of 139. Stoked with the new result I was all ready to commit to training however the last three nights I have gone to do a workout I have not been able to get the power up. On sweet spot sessions my legs are burning not long after the warmup. I dropped my FTP back to 260 to see if I could make it through the warmup without my legs being sore. Still finding the resistance higher than it should be.
I swapped over to the rollers (changed virtual power settings to match) and am struggling to maintain 220w.
I’m not sure what is going on here. Something seems to have changed between my ramp test on Wednesday and my next workout attempt on Sunday. I did two outdoor rides in that time.
I would say that maybe my fluid trainer is broken but I’m struggling on the rollers too. I can’t imagine both have problems. Any ideas on what might be going on? I’ve checked my bike out to make sure the extra resistance isn’t coming from the disc brakes, etc. Same tyre pressure, number of turns on the roller and so on.
