I wrecked several sets of cones in QR hubs of this sort until I worked out that I needed to adjust the hubs to allow for the QR compression. Also, I abandoned using these hubs for bikes with derailleur gears because I broke so many axles, but I know how to fix that now! I continued to use these hubs for fixed gear road use/training/hill climbs and I still broke axles and smashed bearings up, but not so often that it put me off entirely. I learnt a lot through all this....
To add to the info already posted, here are some hub weights;
where SFF = small flange front, SFR = small flange rear, LFF = large flange front, and LFR = large flange rear. Date mark as indicated. Where two weights are given, it is without/with QR or track nuts + washers as appropriate. All LF hubs are slotted type.
SFF Solid Axle 14-91 138/159g
SFR QR Axle 36-86 228/320g
LFF QR axle 28-87 164/251g [revised type hubshell]
LFF QR axle 19-77 156/243g [non-standard cones and locknuts]
LFF QR axle 31-80 161/247g
LFF solid axle 15-77 183/204g
LFF solid axle NA 189/210g [Pelissier without date mark]
LFF solid axle 04-80 182/204g
LFR solid axle NA 294/316g [early slotted Normandy shell, no date mark, spaced to 130mm OLN ]
LFR solid axle NA 289/311g [ Pelissier with revised type hubshell, no date mark, 126mm OLN]
LFR solid axle 25-81 282/314G [converted to M10x1 solid axle, up to 130mm OLN possible, no (Al) spacers yet fitted]
LFR QR axle 26-81 250/342g [130mm OLN, aluminium spacers fitted]
in summary, choosing LF over SF 'costs' about 20-40g per hub in hub weight (but you might save some of that back again if you are able to use shorter/thinner spokes) and choosing QR over solid axles also costs about 40-50g per hub with standard QR skewers.
In a front wheel built 36x3 LF spokes are each ~6mm shorter than a SF wheel. If built x2 the bracing angles are still better than in a SF hub but each spoke is ~15mm shorter. Thus (with 2mm dia spokes weighing ~0.04g/mm) you get 8.6g lighter spoking in a x3 build, and ~20g lighter spokage in a x2 build. If torsional loads are high, a LF build might offer scope for lighter weight spokes to be used. Thus using LF hubs is very slightly heavier, about neutral, or appreciably lighter than building wheels with SF hubs, depending on how you go about it. Needless to say cracked spoke holes in LF hubs are less common than in SF hubs.
