26“ KH rim 47mm wide VS 26“ Nimbus Dominator2 rim 42mm wide.

Hi, I´m choosing between those two rims. Both rims are 36H. The main differences are:

1) weight – the difference is cca 120 grams (0.264554697124555 lbs)
2) width – the difference is 5 mm (0.19685000000000002 inches)

Is it noticeable during ride?

Regarding weight – is it possible to drill holes into inner wall of the Dominator and how much weight can I cut off?
Regarding width – with the same tyre (3“ Duro), could be the ride more stable with wider rim?

Or should I buy some other rim?

Thanks!

So which is heavier?

You could drill out the Nimbus, I would drill the outer wall before the inner one for a variety of reasons. How far you go with it is up to you.

A wide rim will give you a more stable ride with a squarer profile to the tire, but you will be slightly more prone to suffer camber issues and sidewall damage.

I generally think that the advantages of a wider rim trumps the disadvantages but hey, everyone rides different. Both rims are well suited to 3" rubber.

Nimbus Dominator2 is heavier: 850 g, whilst KH Freeride is 700 g + rim tape. I know both are almost the same... considering your advice I think maybe the most relevant is the price

When I built my 26" I chose a 32h TrialTech Race rim @ 47mm and 795g and a Nimbus 32h hub. I drilled the inner wall before I built it up and haven't had any problems but didn't loose much weight either (less than 1oz) as my drilling was pretty conservative. The TrialTech rim was less expensive than either the Nimbus or KH, was in between the two in weight, and had the width of the KH.

The D2 is stronger, the KH is lighter, the D2 is less expensive, the KH has better brand recognition, the D2 is easier and possibly better for tubeless, the KH is 5-7mm wider.

Both rims work fine.

Don't buy the D2 with the plan to drill the rim, you will waste more $$$ of your time, possibly reduce the strength of the rim, and certainly make it less valuable for resale.

If weight is your primary concern, consider a Salsa Gordo or Velocity P35, they are lighter and stronger than the KH, also not as expensive, but they are 35mm wide.

Couldn't agree more. I'm more of a Dominator2 fan as the slight increase in stability and grip you get from the KH rim isn't worth the extra drag and funny handling but each to their own.

Hit the nail on the head. The KH rim relies on the sheer strenght of the aluminium whereas the D2 is strong due to it's high profile and round shape. The D2 is like an egg/football - strong, until punctured.

IMHO, the D2 is a better rim. It handles better, it's stronger, less wide (I prefer narrow rims for smaller tyres and the fact that they don't 'stretch' tyres) but it is pretty heavy. If you're going to run a 3" tyre, however, I highly recomend running a lighter tube. I put a Maxxis 2.75 (I think) in my Oracle 24 and the difference in the way it tackles bumps is night and day.
