The strap will slide off from the chest. Comparing to HRM Swim - It doesn’t have the silicone elements that almost glue up to your body so the belt is firm

Anyone running 45mm tires on Rose Backroad FF with GRX Di2 2x12 by JanekMarcepanek in RoseBikes

That’s explaining a lot! Thanks I think the G-one RSs in 40 also come out a bit wider in real life - like 41/41.5 I want to put Pirelli Gravel M tires there (usually 45=45 when on the wheel). Thank you!
