Wanted: Front wheel, brakes & levers, 42t ring (144)

Brake levers:
Silver cross top/top mount brake levers (tektro make these I think), for road bars (26mm clamp)

Headset:
1" threaded, silver, regular stack height, nothing fancy.

Needs to be the 55-73 mm deep drop ones (nut fitting) FOUND

Snagged some bargain brakes and chainring, but still looking for front wheel, levers and headset, thanks

I have some Ultegra 600 levers you might be interested in

Thanks, but looking for cross-top type:
