This is a long post about my experience with LB U45's. This is a sort of review. I will post my experience with the brake tracks separately.
Build: F28 R32 on DT240s hubs (I sent my old hubs over to LB and they did the rest)
Brass nipples (I live near the ocean and don't want corrosion.)
Spokes: black pillar psr x-tra 1420 aero
Weight - F 728g. R 865g. By my estimates the rims weigh 458g each.
Order process: Good, very helpful. Good english and communication.
Delivery: Very good and packaging was excellent. (see pics.) Build and finish
: excellent from the time they were taken out of the package. I asked for black nipples, they emailed and said it could not be done as the paint was coming off the black nipples from their supplier. I was OK with silver. Good communication, lose 1 point for not having black nipples.Price
: Not very much. Ride:
Truly excellent. This is compared to other wheels that I have ridden: zipp 808, 404 firecrest, Bontrager Aerolus 5 tubular, Hed Belguims, Fulcrum racing zeros. They are truly very very smooth and comfortable. I would not say that about any of the other deep wheels here. They are also quiet. Much more so than other deep wheels I have tried. 10/10Aero:
no idea. Need a wind tunnel / roll test. Give confidence because they look fast. Catching the wind:
very good. did not do a back to back test with others, but I would recommend them here too. Braking:
Ahh, now we have a problem. Day 1 30k of Sydney riding, windy, short steep hills and traffic lights. Using Zipp ZIPP TANGENTE PLATINUM PRO EVO BRAKE PAD. They squeeled horribly and left a thick residue on the wheels. Not normal light build-up but like a block of surf wax dragging across glass. They stopped quickly in the dry, but made a hell of a fuss doing so. At the end of the ride I also noticed a little peeling of paint on the brake track. (more on that later). Brakes were set up toe in and tightened etc etc
Even after smaller stopping efforts I would touch the rims and they would be warm. Probably warmer than the Zipps and bontrager. Not scientific I know, but warm enough that I would notice it as different to the other wheels I had.
Today I cleaned the tracks using citrus degreaser, then water. The brake residue came off easily enough with some rubbing. I then installed Zipp cork pads. 110k ride. 1200m decending as well as traffic lights etc. Not super hard braking, but enough high speed corners that I would be a bit conscious of braking....That's better. No squeeling. They stopped me just fine. Some minor brake residue build up BUT much more peeling in the front rim (where i do most of my harder braking)Summary
Great wheels. Truly very good. EXCEPT for the peeling issue. Until this is sorted out I would not recommend them for anyone. BUT when the brake issue is sorted out I would HIGHLY recommend them to anyone who does not do long descents - where I would get an aluminium rim. free pic
