Park Tool HR-11 11mm Allen Wrench
There's not much to review here. It's an 11mm allen wrench, it fits the freehub retaining bolt on Bontrager and other hubs, it's made out of tool steel and not pot metal, so it doesn't break off in your hand when you use it. It's what you would expect from a class tool company like Park. What more can I say?

Silca Elastomer Seal for Presta Chuck
These seals work great. My old seal had reached the point where it was a struggle to get any air at all into the tires. The new seal popped right in to the chuck, I screwed the chuck back together and gave it a go. The first thing I noticed was how much tighter the new seal gripped the valve stem. I started pumping, and Voila! The air went into the tire, just like it was supposed to, no leakage from the seal at all.
If you've got an old presta chuck that doesn't seal like it used to, get one of these. They do the job.
