    My Light Bicycle Wheels

    Hi Folks, after about a year of reading and a lot of waffling I finally bought a set of pre-built wheels from LB:
    29er 30mm wide rim, 12k,Glossy, 32holes, Red Hope front standard QR/135mm QR 8/9/10s, black pillar spokes and black pillar nipples.
    The cost was a bit more because I got the Hope Pro2 hubs @ $896 with everything.
    I weighted them without skewers and cassette of course and they came out to be just about 1560g for the pair, so that seems pretty good to me. I've already had about two races and 5 rides on them and the verdict is that they are quite stiff compared to my older aluminum wheels. When I try to just crash into bigger rocks to go over them like I used to, it seems to rebound up more. I haven't weighed my bike yet, but I think I dropped maybe 1/2 a pound or so. I'll check. I'll also post some picks here - hope the info helps - sorry but I accidentally deleted the pic of the rear wheel weight.
    I also should note I did not go for the hookless bead just in case it turns out to be a bit of a fad. I usually run 2.2's at about 20psi on the front and 23 on the back when I race and I'm about 168pounds on a 24 pound hard tail.

    I made a mistake saying 1798g it's 1698g for my set with tape and valves. Hadley and Chris King need to get the weight down under 300g for the rear. My new favorite hub now is Project 321 hubs at 285g for the rear with 3 year warr. The Hopes are pretty light, when you think about it the value above, no wheel set at 900 bucks can be bought from any place that will outperform your set !!

    I plan to buy LB RM29C06 or RM29C02 Hookless rims.
    Has anyone Niner Air 9 Carbon frame owner tried is there enough space for wider RM29C02 rim and 2.25/2.4 tires?

    (Cheap) Chinese Carbon Rims?

    I am a "angry"singlespeeder and I need more hill grip.
    I was thinking to do about 1400g wheelset. So what you think, is it possible to make it to RM29C02/RM29C07 rims or is it better to settle for narrower RM29C06 rims?

    My daily rims are 1402g using the 27mm hookless, 1420 spokes (32 hole) and AM 130 and 225 hubs. Rim weight was below spec at 357g and 358g. You would need seriously light hubs and/or low spoke count to get near that weight with heavier rims.

    How much is this wheelset? The profile looks suspect, the rim is only 4mm wide at the rim edge, the Enve are 7-9 mm of carbon, and Light-Bicycle is 5-7mm. 4mm may not be enough material for structure? Anyone care to comment?

    Wheelset is 860. I was wondering the same thing with that wall thickness?

    It does not appear to have a bead hook or a high spot on the bead seat to lock the bead to the rim. I would say that it would be easy to push the tire off toward the inside whenever you hit a rock or root. I would worry about that much more than if the rim would be durable.

    Bead hookless rims are tested and used commonly. Roval has same structure. I´m just wondering that wall thickness outside Xc-riding.

    Enve also are now completely hookless, with 5 year warranties. However, they are 9mm thick wall thickness. My concern is the 1 yr warranty with 4mm thickness. For $860 shipped, it is about $120 more than Light-Bicycle with Novatecs, so I assume that is a good deal to get two DT240s for that price?

    I am aware of hook less, but they have a high Ridge on the seat to help hold the tire on.

    Looking to do the same build, but I can't seem to find a good deal on the 240. Post back if you find anything.

    Sanity check please on spoke length. Used dtswiss calc. Building the 35mm lb rims with 350 hubs 15mm t/a 6 bolt and 12/142 6 bolt rear. Measured ERD at 593. 32 x 3 pattern. Calc came up with 287mm lengths with 12mm nipples for the rear. First wheel build, but I've read a bit, but maybe I'm lacing them up wrong? Laced up the drive side with no problem, go to flip it over and can lace a couple spokes, but then have issues after that, can't even thread the spokes into the nipple.

    What sort of problems are you having? Spoke length issues shouldn't manifest themselves until you're bringing the wheel up to tension. During initial lacing, you're only threading nipples part way, so short (or long) spokes don't cause an issue.

    I think I was misunderstanding the lacing pattern and had the non-drive side spokes in the wrong holes. Got it dialed now after playing around for a sec. What sort of tension do I want to bring these up to? I have a cheap park tension meter. Have them between 15-18 right now.

    15-18 is probably good. Depends on the spoke thickness. Your original problem, you were probably one hole off. I know because I have made that same mistake.

    There is such table in box with parktool TM-1. Needed tension in units on TM-1 scale depends of spoke type (round, blade), material and thickness (and width for blade).
    For example, for steel round 1.5 spoke 18 units match 119 Kgf (good enough), but for steel round 2.0 spoke same 18 units match just 58 Kgf (it's pretty weak tension, for «strong» side especially).

    Did you measure ERD?

    LB says 600mm. But the older hooked version of 30mm outside width rims, which have an identical cross section other than the bead, are listed at 603mm. Maybe they are now spec'ing the actual inner bed dimension, but in the past they were adding 3mm for the nipple flange thickness?

    I have a set of hubs/spokes perfectly suited to 603mm ERD, hence my interest.

    I measured the spoke bed to spoke bed distance as 599. Assuming 3mm for nipple flange the ERD is 602. Others have used 601 and had good results so I did my calcs on that prior to receiving the rims and ordered spokes for a 601 ERD. Hope I'm not SOL.

    I measured across several points on each rim and they appear very consistent.

    Again, this is the 30mm outer, hookless LB design.

    Hope this helps.

    Thanks for the measurements, mattedhead.

    I am on live chat right now w/ LB. I asked them about the two hookless30/24 versus hooked 30/23 rim ERDs, and they told me they are both the same: 600mm. Then I pointed out that their webpage for the hooked ones says 603mm, and asked if the discrepancy was due to the older rim being originally measured nipple-to-nipple rather than rimwall-to-rimwall, and they said "I think so."

    I guess the drawings + your measurements + their statements are enough data to have reasonable confidence that both these rims are identical with regard to ERD/spokes/builds.

    It sounds like you'll be fine though your spokes may be a hair short.
    I prefer to measure using spokes so assumptions are not involved.
    Hey continues to baffle me how some rim manufacturers have little sensitivity to the importance of ERD.

    Anyone looking for great tires for the 30mm wide hookless rims. Bontrager XR3 29x2.30 Team Issue tires. While not super big volume they are light at 700grams, great grip in wet rocks and logs. 50 bucks my shop sells them for, they corner like crazy. They kinda remind me or Racing Ralph but better with stronger sidewalls. Try this tire!!

    I just ordered a set of 29er narrow version with Hope hubs from light bicycle. They said 15-20days lead time to build them. How long is shipping usually taking for most people? I got them hoping to have them for an event at the end of August but I'm starting to think I may have waited to long to order.

    What's the verdict on tape for 35mm and 30mm hookless rims?

    Did some searches and found a few comments but nothing definitive.

    Are the 35mm folks having good luck with 12mm stans (or 3M 8898) tape down the center? Anyone cut down 2" tape to ~32mm for full coverage?

    How about the 30mm (24mm inside) hookless folks, anyone using 12mm? Or is 24 or 25mm tape working well?

    I prefer the tensilized polypropylene style tape (aka Stans) so please keep the efforts to convert me to Gorilla tape to a minimum.

    I'm using 12mm stans with no problem on the 35mm (30i) LB 29er rims. I don't know why full coverage would matter because the holes your covering are small. The tape doesn't know whether it's on a narrow rim all the way up to the edge or in the center part of a wider rim, so why add weight and give up a tape thickness of sidewall height at the bead?

    Here is a reason to use wider tape. Air pressure will try to push the tape through the spoke holes. Wider tape insures that the tape won't get pulled loose as the tape bulges into the hole, especially if one day you decide to ride on asphalt and pump up to 50psi. Maybe Stans tape is so stiff that this isn't a concern. The Noki tape I used is so thin and light that going wide or adding layers is inconsequential.

    I can see for 50 psi that wider tape might be a little better. But stans tape is pretty stiff and sticky, and the spare width of 12 mm is plenty. This is based on about 5 years experience with narrow tape on ztr rims. The tape deforms into the holes but doesn't pull loose at the sides.

    My reasoning behind the wider tape is to create a better seal against the bead.

    (Cheap) Chinese Carbon Rims?

    I used 24mm 8898 on my 35/30 hookless. Wide enough to easily cover the holes. Narrow enough to be easy to centre. No problems so far.
    Tyres seat super easily with floor pump. Fwiw.

    +1. I used 3 layers of wide tape to make setting up tubless easy. Not so nessasary now with a good floor pump but you can bead my tires with a hand pump if you wanted to (what a workout!).

    How quickly are people getting their LB orders? I'm pulling the trigger shortly after weighing a bunch of options, but of course not pumped about waiting 4+ weeks to get them.

    Did they have your rims in stock? If not then yes there will be some waiting involved as to their next production of the type you ordered.
