I have recently picked up this bike as a small project to restore to a reliable commuter. This was my Dads bike years ago, and even at that point it was second or third hand. Since then, it has seen a lot of weather and neglect. But, I think with some basic work and without spending too much money, it will be a nice little bike for getting me to and from work. Plus, in the process I ought to learn a little bit about how these machines actually work.
The first thing I decided to do was replace the tyres and tubes. I took the measurements from the tyres that were already on there down to LBS and got some new tyres and tubes. The back tyre was 700c x 23, replaced tube and tyre no problems. The front tyre was 27 1 1/8. The store only had a 27 1.25 tyre in stock (a gatorskin), so i took that home and changed the tyre and tube (is this where I went wrong?).
All was going fine until I realised that since the change, the front tyre now makes contact with the fork and underside of the brakes.

Some theories of mine that I cannot verify or rule out on my own:
(a) The front wheel being 27" is actually too big for this frame, as all of these are 26". (Couldn't find info on the Katana).
(b) Using a 27 x 1.25 is not a suitable substitute for a 27 1 1/8? (This article helped me understand how much I don't know!)
(c) Perhaps the 27 1.25 Gatorskin has a larger profile than the 27 1 1/8 that i removed?
(d) Something else that is glaringly obvious to everybody but me!
Sorry if this comes across as a stupid question. I have tried to research this without any luck, hopefully someone out there has experienced something similar. Thanks!
If a larger profile wheel and tyre is put onto a frame which was made for a smaller wheelset, then youll have issues. Should get a 700c front wheel, as I dont think these Shoguns came with 27".
I've got the same problem with a Shogun Katana. Did you find a solution?
I bought my bike 2nd hand with 700c wheels front and back. The tyres were from a different size wheel and kept popping. So I put some 700c tyres on and now they rub on the front fork! Merdé! I'd love to know what size wheels the bike came with originally. Do you know?
Sounds like the tyres are too wide or perhaps the wheel is out of true. The place to ask about all things Shogun is here:
