So I recently put Clownshoe rims on the front and back of my pugsley. I did this to run Nates - that tire on a hundie really spreads out nice but keeps a nice round trail profile.
Then I got to thinking... would a BFL fit on this? Since I have a beach ride coming up I thought I'd try. Long story short, I got it to fit with a little coaxing. Behold the girth:
Warning/Disclaimer: I did this to an old, well loved, and well used Pug frame. The pics below show how you could end up damaging a frame. Please don't do this if you are afraid of having potentially disasterous results. 4130 steel is fairly forgiving but it ain't bulletproof.
So... with a little futzing with dish and trueness, I ended up with the BFL and Clown Shoe almost working. There was clearance on the seatstays so that was no issue, but the chainstays were just touching the tire. With perfect dishing I could get the tire to spin for about one revolution with 15psi in the tire:
I decided I only needed a few MM per side, so I made up a c-clamp and a block of wood and decided to do a little cold forming:
Here are the results. On the chain side most of the dent was already there. In fact about 90% of it is from the factory. I just added the little bit towards the rear of the bike. On the non-drive side, the faint crease towards the front was there, I put the shallow dent at the end:
I did take a few precautions here:
- I placed a hub in the dropouts and clamped the QR very tight during forming
- I went very slow and kept test fitting
- I went for a minimal amount of clarance - beach riding only clearance, zero tolerance for mud build-up.
I think it turned out nice. Here is the clearance after, again with the tire at 15 psi. At my normal 8-9 psi the tire has even more clearance:
Also, by dishing the wheel to balance the amount of frame dimpling I needed to do, the tire ended up very slightly to the non-drive side. I ended up only loosing use of the biggest ring in the back when in granny gear. Here is the chain clearance in granny/2nd on a 2x9 setup:
Bike runs an MWOD. I made up for the lost gear by installing the 20/33 chaintrings up front. With the Nates I have no tire drag in any gear so I'll just be sure not to use low/low on the beach. Easy enough.
Anyway, just wanted to share my story. I can say with confidence that its is probably the widest wheel/tire combo that's going on a Pug! I took it for a spin yesterday, and even on standing sprints I didn't get any rub. Looking forward to hitting the beach with this bad boy!
