Hello, forgive me if I haven't looked hard enough through the posts about this, I'm sure this question is addressed out there some where. I have a new Brooks B17 which I bought for my first fixie/SS build. I'm piecing this together through CL, & bought a group of parts someone was swapping off of a Langster London for pretty cheap. Included was the seatpost, which turns out doesn't fit the saddle. The rails on the Brooks are just slightly too far apart. Not too sad about that, wasn't in love with the post anyways, but now I question what posts a B17 would fit on. It seems like Thompson makes a pretty good seatpost, & I was leaning in that direction. But it would be a shame to buy it only to find that the sadlle doesn't fit that either. If anyone has some suggestions, they'd be much appreciated. Thanks.
