Strengths: sealed cartridge bearings. really stiff. Will look good on the mantelpiece - it is a pretty piece great and useless engineering.Weaknesses: pawl mechanism - the design seems to be faulty and chews itself into pieces.Bottom Line: This review is for the top of the line DMR 6 pawl cassette hub. Because of my heavy weight I decided to build myself a heavy rear wheel and laced this hub to Mavic EX 721 rim - overkill for my XC riding, but oh well...
The pawl mechanism ground itself into a fine pulp in 800 km and one season of use. The hub was occasionally skipping from new, but since nothing was visibly worn I could not send it back. Then it self destructed for good and I did not grip at all.
DMR claims that it is wear and tear item and thus not covered under warranty. In my opinion it is simply a design fault - the contact area of the pawls is too small, possibly the surfaces slip by not meeting face to face under load, or the spring in the pawl is too weak to quickly engage the hub.
Due to the slipping issues I do not trust this hub any more (a few times I almost dug my front teeth in the handlebars). My wheel-builder advised changing the hub entirely after seeing the design of internal parts.
