[Closed] light bicycle carbon rims

Tracey, are the rims in a sale then? I can't find any mention on their site or elsewhere.

A saw on another forum they have a new rim coming out with a more in-between width 27/28mm internal irc. So that will be another wheelset next spring for me. It also had an asymmetrical cross section, I wonder how that will build up, especially on the rear wheel where most hubs seem to be pretty dam close to centering the rim between the flanges anyway.

I also believe they are dropping all the other product lines and just sticking to rims from now on.

My AM spec rims are 27mm internal, 33 external.

Took delivery a few months back. Mine are symmetrical though.

You get more options once you start emailing to enquire and spec up.. The site doesn't show all options iirc.

Got them from Bird MTB

I'd opt for DT spokes and brass nips if buying again, just had my back wheel rebuilt locally in DT with brass nipples as I originally had pillars with I presume ally nips.. Rear mech accident snapped a few and by the time the repair guy could get more pillars it was less hassle just to redoo the whole wheel on DT.

Ta Tracey 🙂

Hers mine fitted tonite look great

Quick question, is anyone still buying the 35mm 650b rims?

I'm trying to decide on rims for general trail riding (Peak District, Welsh trips etc) and not sure weather to go 35 or 38mm or stick with alu DT Swiss rims (XM481/EX481 combo).

Any input appreciated!

I got the 35mm 650B rims, not got much milage on them at the moment due to the poor weather, look awesome though. I'm really looking forward to getting out some more and testing them!

Another Peaks rider here been running a 35mm one on rear of 29er for last 6 months, very pleased with strength, weight and width. They make tyres look huge and you may need to check tyre clearance on your frame if you run wider than 2.3-2.4. I wouldn't want the 38mm wide as they're overkill for trail riding IMHO.

Almost 13 stone fully kitted, just a few slight scratches so far and it's taken some pretty rocky descent abuse.
I went with DT comp and brass nipples for strength and ease of availability of spokes.

I wouldn't want the 38mm wide as they're overkill for trail riding IMHO.

they are 32mm deep though, which is aesthetically a lot nicer (imho)

The AM 27mm internal width, external 33mm width are also 30mm deep, so not a massive difference in terms of how they look.

It would seem that 38's could be pushing the limit for 2.3-2.4 tyres.

If you intend to ever run anything less the 35 may be the better bet. You could use the weight saved to up the build of the rim.

26" rim though that

Thanks for the responses.

I've spoken to LB via email and they said the 35mm unless I'm an aggressive rider, then I should go for the 38mm.

To be honest, I've got no idea if I'm aggressive, so I'll probably opt for the 35mm as most seem to be getting on fine with them and I've never broke a spoke let alone a rim!

I originally bought 38mm rims to put 27.5+ tyres into my 29" ht. After I'd decided that wasn't what I wanted I tried to sell them. With no interest I decided to put them in my 'enduro' bike. So out went the hope/flows and in went the 38mm lb/hope rims. 2.35 and 2.2 maxxis fitted, they look huge on those rims.

Considering the 38mm LB rims for my next 29er build. Has anyone had a set built in Leeds or nearby? (Or the 35mm version for that matter).

Just wondered who you had used and who comes recommended?

Would they need experience of building wheels with carbon rims or is it much the sameness as an alu rim?

There doesn't seem a great deal of difference between 35mm and 38mm bar <2mm internal, 7mm depth and a little extra weight.

Just an update on both my sets of 300mm AM wheelsets, both the same with Pro2 and DT Swiss spokes.
Now managed to crack both rear rims on my hard tail and FS, the first one (HT) was my fault for doing a rather crazy drop into a rock garden that would in fairness have tested most rims, the second though (on my FS) happened in late December during a fairly harmless trail ride.
LB to their credit replaced the rim after a short email correspondence within 2 weeks.
I'm not 100% confident on them on the rocky trails I tend to ride here so have gone back to a DT Swiss XM1501 wheelset on my FS, will keep the LB set on my HT however and see how they go, I have a spare set now anyway.

Got pics of the damage Stuart?

They were less than helpful when I cracked mine, i'm pretty sure it was due to the ridiculous spoke tension they were built with

@kingofbiscuits - have a chat with Garage. Al's built a few sets of carbon wheels, including a set of road wheels for me.

My rims arrived today. Black logo! Pics when built

Can you post a pic of the rims with the black decals please Coolhand, I've just ordered a pair myself & have only seen their computer images...

Ta.

Good shout @TomHill, I'll get in touch Al @ Garage. Thanks.

Scaled
This one is my own fault so I replaced the rim out of my own pocket, its was 2 rides in.

This is the recent damage on my FS, replaced very quickly under warranty, the wheel-set was about 5 months old and had done around 800km of riding.

With both the wheel-sets I replaced all the LB supplied nipples as those seemed to be made of cheese

these all suitable for disc brake road bikes? in the appropriate drilling

http://www.light-bicycle.com/carbon-road-bike/carbon-road-cyclocross-U-shaped-rim

I've been thinking about a set of those too, disc version is a bit lighter if you specify no rim brake surface. If you're running tubeless or regular tyres and tubes you want the below link (your link includes Tubs just in case you're not aware).

new rims

http://www.light-bicycle.com/EN928-asymmetric-rim-profile-carbon-29-inch-mountain-rims.html

hello,
I've read many discussions yet i am still 100% unsure what is the correct spoke length.
I ordered 33mm AM 26inch rim ERD 515 mm to be laced on Hope pro 2 evo hubs 20mm front and 142x12 rear. I used prowheelbuild calculator and got these numbers:
rear Left spoke length: 249
rear Right spoke length: 247.8

Now here is the confusion as most people on forums claims that erd is wrong and extra 3mm of spoke length is needed. Would it be caused by people actually using shorter nipple (12mm instead of 14mm) as from what I managed to find it seams that wheel builders at light bicycle are using 14 mm pillar nipples ? I ordered pillar aero spokes of extra 3 mm lengths (251mm and 252 mm) from them so I really need to know. Should I stick to 249/247.8 and use the supplied 14mm pillar nipples or just leave it and use 251/252 and my own 12mm nipples?

I've replied on the thread you started.

Just dropped my rims and hubs off for building. Builder asked if I wanted 2 or 3 cross, what's the general consensus?

I know 3 cross is standard mtb but he suggested 2 cross might give a more compliant wheel.

Disk brakes = 3x

Everyone will say that, I doubt anyone knows.

I doubt 2 cross is more compliant tho.

Exactly al, it's such an imperceivable difference both ways, why mess with what works?

I'm looking at the 27mm rims to build up as an XC race only wheelset.
The flex in my crest wheels I race on now is frustrating.

I'm 65kg, I wouldn't say I am anyway an aggressive rider but I get things wrong like anyone occasionally. I have put minor dings in one of my crests twice, so not too bad over a couple of years racing? LB have already recommended the 30mm rim? As if they don't trust the 27mm rim themselves?

To be honest, I am more interested in the stiffness of the finished wheel, but Can't figure out if the 30mm will be much stiffer if at all? Anyone using either or both? I am thinking of just getting the 27's as they sound the tool for the job.

my 650b 27mm rims just arrived, I ordered less than a week ago! these are going on the gravel bike. I was tempted by the 30mm but I prefer the profile and depth of the 27's.

Has anyone got any experience of the AM728 or EN728 Light Bicycle rims or any of the other newer ones with the asymmetric profile?

I'm 95kg, my 27mm internal width lbs are holding up fine, including a pinch flat on a stoney downward slope on a bridal way, stones a fairly even mixture from gravel to fist sized stones, I was going at quite a pace so couldn't stop immediately for fear of flying off, so I must have ridden about 30 to 40 feet with the front wheel riding on the rim. The tyre didn't come fully unseated though so offered a bit of protection. Not a mark on them bar a couple or realy light cosmetic scratches on the rim wall.

Thread bump

I'm pricing up a set of wheels and the total is coming out at $1060 + $78 shipping + $40 paypal fees.

According to dutycalculator.com I'm looking at £204 import duty & VAT to pay on that for a grand total of pretty much bang on a grand. Does that seem about right, or at least worst case scenario?

UBYK now have 34 & 40mm LB rims on Hope Hubs for under a grand

I should hope so too, I paid about £650 all in including import fees on a fully built wheelset on pro2 evo 40t.. have they put thoer prices up?

I paid £35 odd customs on mine

For a lot less hassle, built in the UK and far easier warranty if they go wrong, I would check out any of these. Only ones I have actually used are the Superstars and not had a single issue in over a year of hard riding.

Bird bikes Carbon wheelset looked great vfm, hoping that reappears soon

Also have a look at Sixth Element wheels. Abigale has a pair of 38mm 650b hand built on Hope hubs and so far have been spot on.

Use your old hubs. Mine cost me £230 all in, spokes, nipples, import duty and rims. Built myself. Very straight forward.

Thanks for the alternatives, some food for thought. Would be after 29", 28-30ish internal width and with Boost flavour hubs which narrows the choice bit. From the LB options I was thinking of going with DT Swiss 240 hubs to save a bit of weight versus Hope.

nice video from them

A bit light on substance, but interesting that they're obviously aspiring (or marketing themselves at least) towards the top end of the market rather than the prejudiced view that they're in it for money rather than producing a quality product.

Wonder if they'll ever appear as OEM with their own name on the rims?

First ride out tonight on my LB 30mm xc wheels (Dt 240 rear/Superstar front,D-lights,me builted).
I never really realized exactly how flexy my original Archs were!!! Whether the extra stiffness is an entirely good thing I don't know yet.Once I got used to them actually going where you steer them I did find they were knocked off line a bit more easily.Whether that's due to the stiffness or being about 500g lighter than my old wheels I'm not sure of yet either.
I do like the added whizziness and get pinged out of berms like a bullet from a gun though!!

An update on mine that I've had for about 1 year now. I've now ridden them twice in the Alps. Once, a holiday with Ride Slovenia, and the other week I was using them racing in Enduro2. I have used them racing in UK and normal trail riding, although I do have another set of wheels that I sometimes use dependnig on weather and tyres. They are still perfectly in 1 piece 🙂 they have scratches on them (maybe I should have got the matt finish), and I might have snapped a spoke (I think it was these wheels). My team mate @ Enduro2 was running alloy rims and his suffered at least 3 dings. These carbon rims are far tougher than most alloy rims. The Alps stuff they have ridden is likely to be the fastest/rockiest trails most people will ride/race on. Other than full on DH race, I cant think of anything tougher they would be put through.
