I really dig Phil Wood products and rate them highly. That said I don’t know why they think EAI cogs are sub standard? I’ve found them to be well made, accurately machined and good value. ---

I believe their justification is that the EAI cogs are slightly thicker than others which prevents the lock ring from threading on as far as it should. I don’t have a clue how much evidence there is behind this, and if there is a difference in thickness, it wouldn’t surprise me if its effect was negligible. ---

I’ve found them to be well made, accurately machined and good value. they don’t, but they don’t make money out of ppl not buying their premium-priced cogs 😛 ---

> [@The\_JAMS](#): > > they don’t, but they don’t make money out of ppl not buying their premium-priced cogs 😛 Phil W could care less about that stuff. If you do some digging around the company you will find their is an immense amount of pride in their products. It also remains a small company committed to producing (and standing behind) their items. IMO the price represents the quality of the US made gear. But back to the issue at hand. From [here](http://www.bikeforums.net/archive/index.php/t-74592.html) as I knew I’d read this advice before. > [@Brent & PW](#): > > 11-11-04, 10:32 AM > Please don’t use Surly (ISO) cogs on our hubs. We have seen about 8 stripped hubs in the last two year, 6 with Surly and 2 with Soma. Surly cogs do not engage enough thread and the ISO threads do not match up which is why it was rough going on. I have also heard they are redesigning them, just don’t know when. > Soma cogs are ISO also and tend to seize, something to do with the plating they use. Plating will also tend to “pool” in the valley of the threads so it will round off our nice threads even more than others. > > DA cogs are the best bet that we have played with. > Ours will be available in about two months. > If anyone has any questions on the subject feel free to email me at brent at phil wood dot com. > > Thanks, > Brent Also (although he seems to love his EAI). > [@11.4](#): > > Brent has the issue nailed with regards to threading per se – don’t put ISO threaded cogs on a Phil hub. But as for the question of how wide the cog flange is, I’ve pulled out my box of cogs (26 at last count) and found that even within one brand, there’s 1-2 millimeters of difference in width. I found this with Dura Ace, with EAI, and with Campy. They tended either to fit properly or to be a little bit thin, in which case a bottom bracket spacer is just what you need (they come in all kinds of thicknesses from about .5 mm to 3 or 4 mm). You definitely don’t want to have slack for the cog, because if you spin the cog loose and it then comes up against the lockring, it’s the perfect scenario for stripping threads. There’s no recovering a hub after that – it’s kaput. I also checked a number of Phil hubs I have and found almost 1 mm difference in width of the BSC threaded portion, which might exacerbate a problem from time to time, but the cog is the main culprit. The EAI cogs, by the way, were not perfect but were at least the most consistent. I’ve found they outperform everything else out there (except of course, Brent, the new Phil cogs that haven’t arrived yet). I do remember the early surly cogs being thinner and there being some additional issues with them mating correctly with some hub/lockrings. I was sure that it had been addressed.
