250gm Light Bicycle 700C/29er carbon rim

No, but a friend has some of their MTB rims which he really likes and they've been faultless, so I'd be happy using Lightbikes. I was looking at their fatbike rims, I could save a pound off my fattie just in rims! Question is if I use it enough to justify that sort of cost...

That's a gravel/road rim, so if used for it's intended purpose and nothing beyond...might be okay? That said I see there is a cross country equivalent at the same weight, which I would be more concerned about. Anyone else making rims of similar weight? Surely there's only so much material that can be removed before there ceases to be anything left?

I've got a pair of Nextie 310g 25mm internal rims, which have held up just fine to xc and light trail for several years. Roval's lightest XC rim is currently 358g 29mm internal, which I've also got. Going by the difference in ride feel between those two I wouldn't want to take another 50-60g off and use them the same.

I've had lightbicycle rims forever, I got one of their first gen 26er rims way back (because it was the only thing I could find that was a straight swap for a bent roval rim), beat the crap out of it, it was properly xc race light but I put it in a hardcore hardtail, broke it after a few years. Rode on it for a week after it broke. Then they gave me a crash replacement discount which I put into a pair of the 2nd gen ones which I put in my big bike for years, sold em on when 26 became uncool... then built a 29er set that I'm still using today- did break a rim in that one but again, was fair enough, they've been in my enduro bike for years now (and I got another discount on a replacement). They do great kit. I should probably say I am light but that doesn't really make a lot of difference, what tests rims is what you whack them into 😉

I think gravel covers so many bases though, if I had a gravel bike it'd be getting hammered and ridden on stupid stuff and I'd not put a superlight rim on it, tbf I'd put an XC mtb rim on it at least. But if you're using big tyres and never bashing rims then maybe it makes more sense.

I’ve got those rims on my gravel bike.  They’ve now done around 1000km of gravel, potholes and accidentally riding into the back of an abandoned car.  They seem robust but feel light to the point of cheap when you first open the box.

Thanks all, I understand LB have a good reputation, it was just a bit of a wtf moment as they are so light (tho I recall PX doing some 265gm tubular rims years ago tho).

I'll have a think ... £400+ does seem a lot of cash, my road bike frame cost £100 a few years ago (wouldn't have the clearance for tyres wide enough for these rims) and I'm still on 8-9 speed! Also I see only 28H drilling which is annoying, 32H my preference.

Mine are 24h… :-/

I paid £325 for the pair.

I'm on the AR35 and they've been faultless for 3 years (road, gravel, a few novelty laps of the mountain bike park). I've never felt the need for anything lighter. Worth noting that they list the maximum rider weight for the AR25 as 90kg "on flat ground". Given that these are the lightest of all their rims, I would assume only really suitable for road riding.

They used to offer any drilling you chose as a custom option on request- not sure if that still applies, I think some of the rims aren't just drilled but are a little bit built for the holes.

24H option is showing then I follow the link above.... They'll do anything custom if you ask.  Been running AR46 on my gravel bike and now on my road bike with no issues.

XC option looks like a better bet for many for gravel. More impact resistance rather than sidewall reinforcement for high tyre pressures. XC one is rated to 350psi which is more than I’d run in 45mm gravel tyres.

@daffy £470 now, what's the import tax situation please?
