I'm looking at getting tyre inserts as I want to run lower pressures but avoid bumping against the rim all the time.
So far I've seen -
Cushcore Pro (Expensive and heavy)
Nukeproof ADR (Inexpensive and light, but they stretch)
Huck Norris (No idea)
And now a new one from Tannus...
Went for a ride with the new bars and they feel fantastic! I'll experiment by swapping a 10mm spacer on top and seeing how that feels but otherwise, the more upright position means I don't feel like I'm tipped forward as much and I felt much more stable on downhill and rocky sections.
