It’s been a learning experience and very interesting comparing it to my other 2 rides ( Factor one and Colnago v2 R)
Here are a few of my thoughts:
Moving from a bike with qr to a bike with thru axle ( as most disc bikes are)is huge difference.Bike is a LOT more stiffer.Some good some bad.Good for acceleration bad for overall comfort.
Add to the mix your favorite cool looking deep section wheels and you add to the stiffness some more.
If you riding a package that is aero,disc deep sections ,thru axle wheels im sorry that must be the most uncomfortable ride EVER.I know the guys with venge will slate me but where I am there is a far mixture of A B and C roads and the moment you go off anything but smooth tarmac you feel the difference.
Disc wheels are heavy and have a bit of catching up to do to their rim brake counterparts.
Although my disc bike comes in at a not bad 7.3kg I can definitely feel the extra weight in the wheels compared to my rim brake bikes when climb and accelerating.
Will disc take over?No,I believe manufacturers will continue to produce both.
My advice to those going disc.
Don’t go aero and don’t be tempted to go cool looking deeeep sections.Imo coupled with thru axels it just makes a uncomfortable package.
My 2 C
Here’s what I’ve experienced.
1) Disc RIMS are lighter for a given depth/width/profile.
2) Disc RIMS can be more aero.
3) Disc wheels are stiffer, as they almost always have more spokes than their rim brake counterparts.
4) Thru axles don’t make any difference in comfort.
5) Disc rims can be wider for a given weight. This CAN result in wider tires, and more comfort based on what tires, inflation system and pressure a rider will run.
6) Disc rims, particularly those without hooks, can use different construction methods and materials that build a more durable wheel.
