i know some here may have different views but if there is lots of tread what dont you plug it ?

am i the only one that carries plugs and C02 ?

Not anymore. That bike is gone.

2 things I hated about spokes - the chrome went to shit and flat tyres

have you tried balmain tyres ?  they may stock what you need and if you call ahead they can usually do while you wait .  a 50 profile on a 200 will theoretically reduce the overall wheel diameter by 20mm . so your seat height will reduced a little bit less than 10mm
