Question How to proceed

[gister63]

.
I had a nice Trek stolen a couple of weeks ago. I don' t drive so my bike is my friend and I need to get this bike ready to ride ASAP.
I need to remove the(I would call it a sleeve) so I can install new brake calliper I have attached a link with a pic.

Thanks in advance

It might have been attached with epoxy. If it cannot be unscrewed, then drilling and taping new threads might be needed.
You could try using a low temperature flame to soften the epoxy - a butane cigarette lighter, not a hot torch.

I think you should try the JayKosta solution with attention paid to timing, if the mild metal reacts to the heat and whatever is holding it in place you can use diagonal pliers with some sharp knife edge and a hammer to try and get it to move upward. Or you can delicately use a Dremel tool with small grinding wheel.. Touch it to the bezel momentarily and see how deep into the brass material you have gone through.. I would take the grinder and make a small notch if brass material and use chisel or small flat screwdriver to see if you can get the brass looking piece to rotate on the brake stud braze on..being careful not to go crazy and bend it ..you don't care about the frozen on part so maybe even a gentle grip from Visegrip type locking pliers might get you enough bite to get it budge.
Also a bike shop that services or sells older bikes might know a trick.. You should be optimistic and have smile and beer as you walk in..I always pretend that everything is easy for them and hard for me..flattering bike mechanics is very effective.

Can you get the entire stud out?

No I can't. I have tried combing my hair differently, wearing less than desirable clothes, backed off on grooming, drink an extra 2,3, can't get the stud out.. Lol..

I am super curious about if 32 wheels are going to be an easy adoption in racing. Shorter crank lengths look to be semi adopted, but riders who are on @54-56cm frames or smaller I don't see how this can work. I have crossover with 170s, Shimano shoes and pedals, running 30mm tires and cleat location is fairly standard from what I know..
I wear a 44 shoe and my toe with crank at 3 o'clock is into the front tire by a @centimeter +. Bike is typical geometry and fork rake, no crazy short or long chain stays.
How are designers going to maintain a fairly standard wheel base and use bigger, taller obviously wheels. Unless you let the head tube relax a bit, extend chain stays, maybe take fork tube angle out a degree or so, where do you fit two bigger wheels trying at same wheelbase and similar tube lengths? I don't see how your foot( toe) doesn't hit the front tire at every slow speed turn while pedaling.. I don't think people want cargo bike geometry even if the wheels are dope..

I have never ridden this type of geometry but I hate the way it looks..
