Hi all looking for some advice regarding rim width for a new set of 29er wheels. I want to upgrade from a set of dt swiss spline m1900 mainly because they weight 2kg and are on the narrow side with ID 22.5 and the rear hub doesn't have the good dt swiss rachet inards. Number one reason for the upgrade is to drop weight. Rest of the bike (intense spider29) is very light so I want wheels to match. I have already decided on carbon, most likely either nextie, light bicycle or zelvy depending on funds. I ride all the stuff everyone else does around Melbourne so it's mostly angry xc with the occasional black diamond sort of level stuff like the youies, parts of plenty gorge etc. Basic trail riding really. So my dilemma is this, go for a wide carbon rim ~ ID 30mm and lose very little weight but theoretically more grip ? (with hopes/dt swiss hubs) or go a narrow more xc wheel ~ ID25mm and drop 1/2 a kg.. I don't know if I am really sold on the whole super wide rim hype.. i run a 2.35 Hans D and 2.25 NN and wouldn't really go much bigger on the tyres, so I question the real world benefits of 30mm ID on these size tyres. A mate has a set of 30mm ID and doesn't really notice any huge benefit other than they look cool.. (which they do) So I am wanting opinion, lighter narrow rim vs a wider heavier rim for general trail duties.. I peddle everywhere and don't shuttle (unless on holiday) so big draggy wheels are of no interest.. I notice Enve and Mavic aren't falling over themselves to jump on the latest trend. And the ex maxxis tyre designer over on mtbr reckons benefits are minimal over 25-27mm ID (so does Enve).. Then the rest of mtb press are falling over themselves for bigger and bigger rims even though there is proof the current 2-2.35 tyres corner shit on >30mm wheels due to the tyre squaring off. I'm confused.. I'm sure this has been discussed elsewhere here but I can't find it. I'm thinking ID 25-27mm is the sweet spot for my riding? Thanks..
