If you are anywhere near 43rd ave and Bell- try Swiss American 602-938-4330. They carry everything you should need and can capably do the work. Tell them Cory sent you. If cost is a real constraint- buy the gusset set above, a SS front ring and a SRAM pc-1 chain and I can help you install it (I live near 7st and the 101). For a tensioner, I REALLY like the Soulcraft convert. It does not slap around like the others and is buttery smooth and silent. They are not the cheapest- but in my book the best. Swiss carries all this stuff usually. Tell them Cory sent you! And don't worry too much about cost. If you are like me you will love SS so much you will sell your geared bike anyway!
