ISO jack Brown

[spencer robinson]

I am looking for one or 2 Jack Brown tires. I am trying to fit the largest tire that makes sense on my Heron Road. I can get a 700x35 on the front but too tight at the brake in the rear, I think a jack brown will fit the rear, as a 700x32 gravel king is no problem with room. 

I think the 1st gen Heron Road was built around short reach brakes so the rear is tighter.

If anyone has a jack brown in their tire pile or a pair, I would be interested 

Thanks
