Yup - if you are not getting pain then this is possibly a good thing. Because where do you stop? I had to use a rolling pin a few months ago, but then reverted to a better training and mobility regime and weirdly all my problems disappeared.
Have a think about your training (cycling technique, and the fact that your legs are not as strong, balanced or mobile as you think), diet and recovery (rest is important!) and you may find you are served much better.
It's more a case of, why are you performing these mobilisations/soft tissue work? Is there a specific reason? Is it actually helping you in the gym for specific movements etc or for other activities?
If you can roll your ITB without squinting mind, good work
Will spend a bit more time ensuring I'm doing it 100% right.Just carry it out along with stretching after hard (Time Trials 1 hour at max effort) or longer rides really. I don't do Gym work, just want to ensure I'm cover myself off to ensure my muscles can recover/restore/build as well as they can.
ITB was horrible at first, I wouldn't say I don't do it without squinting, but certainly can roll them without wanting to cry anymore
A time trial cyclist that doesn't spend time in the gym? How interesting... All that aero and skin-right Lycra, and you're as strong as an Andrex puppy!
Just kidding.
But seriously, getting some strength training - even stuff at home - will have great carryover into cycling...
besides don't want too much excess weight Ah - it seems somebody is in need of a bit of re-education...
No need to cost you anything at all, just do the following at home for 4 sets of five reps:
- Bulgarian split squats off a bed/chair, using any additional weight you need;
- Inverted rows off a dining room table
- Chin-ups off a loft hatch
- Push-ups at various angles...
You get as big as you want in the gym: eat lots and go for sets of 8-12 reps and you will pack on size... Keep the reps low and eat a bit more balanced food than normal and you will just get stronger.
Put it this way... I know several cyclists and runners (some pretty good ones, too) and they have all said that even a little bit of weight training has moved their sport up several notches and stopped knees, hips and lumbar hurting.
Try it. Stretch your horizons a little... There's a whole new world outside that door...
will give those a go. Do the last 2 already and some kettle bell and chucking an old battery around but will look specifically at those. Tbh during the summer when I do no running I have pretty much no aches or pains only when I chuck in a bit of running that my legs start to feel anything but tired (just doms probably) but will give the first two a go to supplement the other stuff I do. 
I do stretch but will do more so - as always, you are likely spot on
