All same size rim? Tubes? Tubeless? I’m building up a new roadie and waiting on some 25mm GP5000 tubeless tyres to show up in the mail. Hoping they dont bulge out too far on my wheels for that supposed aero gain.
If they’re the tube type, they changed the size to more accurately reflect the rims people were using - the old ‘28’ which may have measured 28 on 13mm internal rims came out as closer to 32 so they sized them down a bit. They may explain some of it…
Got one a couple years ago. I use it all the time. Pretty useful for the bike tool kit but also entertaining.
Right up there with my Infrared Laser Thermometer in terms of actual need vs taking random unnecessary measurements
Holy crap! I’ve been running a pair of 28mm GP5000 clinchers purchased in Sept. 2000 and they measure about 30.5mm wide on Hed Belgium Plus rims which are 21mm internal.
I recently replaced one of the tires with another 28mm GP5000 clincher purchased in May 2021 and it measures 28.7mm. Manufacturing tolerance or change in construction? I’m aware there was a big change in labeled vs measured width from the GP4000S II as the 28mm size of that model measured over 32mm on these same rims.
All measurements taken with my super precise and highly accurate $10 Harbor Freight digital caliper.
