My two pennys
Wouldn’t disagree with the above recommendations but I found DX bearings fiddly to adjust and couldn’t swap to the longer pins from new so never really used them.
Have Straitlines on the mtb which are good but wear easily/require new bushes too soon(pricey)
DMR V8s on my commuter (3000 miles last year alone). Were on various bikes before. Purchased new when I worked in LBS in 1997.
Never been serviced-they do rattle but thats a ‘security feature’ when on trains!
Name another mtb component that has had daily use without attention for 15 years!!
