Surly Rolling Darryl rims…
I was curious how much weight my wheels would lose with my swap to Rolling Darryl rims and possibly going tubeless.
- Rolling Darryl rims +890g [powder coating is ~30g]
- Surly rim strip +95g
- Stans 3oz +90g
- split tube +175g
- Surly fat tube -425g
- Large Marge DH -1150
- rim tape -50g
Net loss per wheel is 375g or 0.83lb if I go tubeless or 215g/0.47lb if I stick with tubes.
Some people are going fat tubeless without a split tube for even greater weight savings – maybe 475-500g [~1lb] per wheel assuming some extra foam/tape/sealant is required. I think I’d just use the split tube since it seems so easy/reliable.
For interests sakes I weighed an Endomorph and it came out to 1200g which is on the light end of the fat tire spectrum so I don’t see any weight savings available there.
I am not sure the weight savings is that big of a deal going tubeless on a fat bike – probably a bigger deal is the tubeless fat tires roll a fair bit earlier, especially when using lower pressures. That alone is worth it, if your rims work well setup as tubeless. YMMV of course.
The difference in rolling resistance is a big plus with tubeless, but wheels that are nearly 1lb lighter will be noticeably easier to accelerate. It’s a win – win situation.
I didn’t weight my 45Nth Husker Du ultralight casing tyres before I put them on the bike but they claim 1,240g. Impressed that your endos are lighter! I got the HuDus for the tread pattern though, as the fattie is likely to see some pea gravel and hence the side knobs will hopefully be useful.
My 9:zero:7 will hopefully be up and running by the weekend!
