I'm just finishing a single speed 29er (#47), using Paragon sliding dropouts. The chainstays are True Temper s-bends and the seatstays are True Temper 19mm.

The chainstays are 415mm (sliders all the way in), which is the shortest chainstay I've built yet. I was getting ready to weld the chainstay bridge in, which I've put on all of my previous bikes, but in looking at the spacing it looks pretty tight. There is certainly room to squeeze it in there but it looks like it might cause a possible spot for mud, stick and leave catching.

Do most of you put chainstay bridges on mountain bikes with shorter chainstays of this length? I realize short is all relevant to the builder.

The rider is about 190 lbs and a the bike will be ridden pretty aggressively.

Thank you in advance for you comments.

Tom
