Greetings, all. This subject has been tackled before, but of course each situation differs, no? Very recently, I began to notice a squeaking/grinding noise while attached to my Cyclops TT2. It starts about 5 minutes into my ride and is annoying as hell! It apparently is eminating from my b/b (2004 Chorus, which is less than 6 months old). Just in case it was my pedals, I lubricated the surface of my Pro-Fits...nope not them, although they can squeak like the devil when 'dry'. Anyway, I got off the trainer, grabbed the crank arms and torqued them a bit and it actually sounded like the frame was squeaking - I ride a 2002 Colnago Master-Lite. Indeed, the sound reminded me of a squeaky seatpost, but that's not the problem. I got back on and there's the b/b noise again. I asked my g/f to have a listen and she, too, figures it originated from around the b/b. Now, when I pop my bike onto my rollers and spin away, no noise - even hammering in higher gears. Mind you, there is less stress on the frame on rollers. So, short story long... is the trainer stressing my frame (in addition to the rider!!)? Anyone else experienced this? Thanks for any insight.
