I currently run Mavic 823 rims with DT swiss 240 hubs ,Run them tubeless with UST tyres and they've done me well and reliable.
Problem is with me being a lightweight i dont really need the the heavy DH ex823 rims and they are overkill for what i use but on the other hand i like the reliability of the rim.
Ive been using a rear Mavic en521 rear rim with pro 2 hub for a while now as i found one cheap and always liked hope hubs alongside the ex823/240 combo upfront as my rear 240 hub needs a bearing change.
Ive checked the rim weights the 823's are 657g and the en521's are 570g.
Is it really worth me going for another EN521 rim upfront with the small weight gain as id obviously have to run them with tubes unless i go ghetto tubeless and then sell the 823 rims?
I also have the option of running non-UST tyres on my current rims to save a little weight.
Whats everyones opinions ?...Is it worth me buying another pro2/en521 wheel upfront and replace my current rim or stick with the 823 rims and replace the rear 240 bearings?
