Clamps for double-rail Brooks saddles?(3 posts)

Clamps for double-rail Brooks saddles?Humma Hah

I adore the outrageous B73 saddle I bought for the cruiser recently, but did notice the clamps were pretty cheap-looking sheet metal stuff. They held up OK on the street, but last weekend's run down the C&O towpath they were failing. They'd slip (allowing the seat to rotate nose-up), I'd tighten 'em, and by the end of the day they were crushed.

The B73 is double-railed, i.e. two rails on each side. The seatpost is 20 mm (standard American cruiser diameter). There are adapter sleeves to allow clamps for fatter seatposts to be used.
Have you tried one of these?carpe_podium

Not sure if your post will work with this but it looks like it's made of machined aluminum. Maybe you could buy an alloy post and drop a few grams off of the old girl ;-)
That ought to work ...Humma Hah

... The B-73 is basically the B-66 they picture with a third spring installed under the nose. They picture the Brooks clamp that failed, and the micro-adjust clamp they show is basically like the one I just got for the Paramount (which probably will get a B-17 for X-mas).

The only question is if I can get a micro-adjust clamp that either comes on or will fit on a 20mm post. At that small a diameter, it probably needs to be steel. Most modern posts are 26mm or larger. I might be able to slip a modern post on the existing post with a little modification.

Shed a few pounds? Heck, the B-73 ADDED about two! That's one of the things I love about it. The outing on the C&O that ruined the clamp was otherwise a success ... I left the two MTB's I was with behind, barreling thru mudholes that were nearly stopping them in their tracks.
