That is the thickness of the cog you are citing. The center-to-center spacing of the cogs is a much more critical deminsion for determining index compatibility.
Anyone have an idea what the R derailluer cable pull ratio was for suntour? I suspect it was probably very close to the normal (non early Dura Ace) 1.7:1 ratio used by shimano but it would be nice to have the exact ratio for suntour to calculate mis-match index drivetrain possibilities like at; https://www.ctc.org.uk/desktopdefault.aspx?tabid=3946
Konaron- Interesting that you are getting brake shudder with V-brakes, usual reason for the shudder is blamed on cable arrangement of cantilevers (flexing fork changes cable tension) which V-brakes are immune to. Clean the rims and pads, play with the pad toe angle and you can probably elimate the shudder.
Spongey lever feel = excessive amount of mechanical leverage of the system (and/or overly flexible brake caliper arms). Switching to V-brakes with shorter arms may help stiffen up the lever feel.

Hi Oldpeddlar...typically aero levers (and especially STI) are not good with v-brakes - these Tektros are built to work with v-brakes. Another option is using a travel agent, but I didn't go that route because it adds complexity and the Tekros were perfect for what I wanted anyway.

The shifters are Suntour Commands and are separate from the brake lever...they were Suntour's attempt to compete with STI in the early 90s and it didn't take off. They're the first time I've used them so I need more time to pass judgement. So far I like them a LOT...you can shift from the drops, flats OR hoods. They aren't as smooth or precise as STI, but I'm also not running them with the Suntour derailleur/freewheel they were designed for. That's probably affecting performance (they do work quite well as is).

Thanks man! I like it even more with the Huffy decals...
You could always have your US friends source you a pair...it wouldn't be that difficult. Some other options you might want to check out are Kelly take offs and Paul thumbies. There is also a recent thread about some brake levers with a thumb shifter attached - they're very cool.

Nice build, Aaron. My son was just yesterday hinting at buying me a set of studded snow tires for Christmas, and I had to reluctantly tell him no. I just can't justify that purchase for the amount of use I'd get around here (Detroit area) where the snow just doesn't last. I'm curious, though -- my son said his reading so far indicated that studded tires were available only in the 26" diameter. Is this true? Because I don't own any MTB's, just road bikes and three-speeds.

What he said ^
Holliday - maybe we'll go the shipping route?

We could probably do that if that's what you want. My schedule is really screwed right now, but I am in Phoenixville every day just about if you wanted to stop by. Otherwise let me know and I'll box em up and take them to USPS.
