Absolutley dreadful…
One came on my Ribble TiHT which i’ve had now for nearly 18months. In that time the release assebly dissassembled itself, locking the post down mid-ride. The sealing cap keeps coming loose despite having locktite on. I’m pretty sure the manufactuing tolerances are just so poor (like the bike sadly) that the cap is just too lose to stay in place.
Even when new it had quite a bit of play that got a lot worse. Despite stripping it completly down, cleaning and regreasing it, its now very rough to operate.
I returned it to Ribble to try to replace under warranty but they said it was all within specification and refused.
Sadly I would avoid anything with the Ribble name on it.
