Only if you tried to sprint or take a sharp corner. Luckily the pair I rode were borrowed, I didn't keep them long.
Edit: it won't matter if it's a track build as you won't be doing any of those things and you won't get brake rub every time you get out of of the saddle to accelerate.
Thanks for the heads up about both, really wanna give them a go because heard loads of good things about them too. also found some stiffeners for if they're too flexy for me so could well be worth a try as well.
