Shimano BR-1050 SLR brakeset

[F150]

Anyone with firsthand experience with these calipers? Ended up with a pair (39-49mm reach) and it appears as though they are made to work with the corresponding BL-1050 levers. Something about a lighter spring in the caliper, and brake levers having a second set of springs built in. Unfortunately, I have no such 105 levers (1050 std/1051 aero).

Will they work with a standard road lever, or not so much?

Very clean, very good condition; hoping they fit my son's old steel Fuji as we go from 27" to 700c hoops this weekend. If too short and someone had the longer reach version (47-57) (and needed these shorter reach dudes), I might consider a trade.

I have used these brakes with a variety of different levers. They have proven to be fine in all cases. Off the top of my head I've used these:
600 tri color
6207 levers
7400 levers
cheap tektro bmx style lever (this has given them the most power sending my wife OTB):eek:

Thanks. Have some perfectly fine Suntour aero levers I figured we could mount and try without too much effort. Reach to the 700c wheel is going to be borderline. But as much work as I put into resurrecting this thing from a stuck seatpost, I just can't bring myself to put it in the trash heap (even though son longs for a modern ride).
