Thanks.

Any suggestions for a U lock? Currently we have Kryptonite "Kryptolock Combo" U locks. We started using these when the kids were small and couldn't be counted on to not lose keys. My son parked his previous school bike (Novara hybrid w/ basket) outside his middle school using this lock, three years and the bike was never stolen. But I've read that combo U locks aren't that secure, and I'd like a U lock that locks both legs and requires two cuts. What would you suggest for a U lock that is keyed and locks both legs? Would you recommend a full size or a mini?

How about a chain? What would you recommend? I have never used a chain lock - truth! I started using Kryptonite U locks back when they were made from flat straps of steel (late 1970s?) and have used nothing but U locks since. So I don't know what thickness of link to get, whether to get an integrated chain or a separate lock, and what about those "noose" styles? I figure he'll leave the chain at school so it can be a long and heavy one. I'd like him to use the U lock on one part of the bike (e.g. stays and rear wheel) and the chain on another (e.g. downtube and front wheel).

Finally, the locking skewers. What is the best type? I'm assuming these are optional if he uses both U lock and chain at school, as described above; they would really be for when stops other than school.

Here is the bike he's locking



Sad thing is, the locks will end up costing more than the bike cost (a Craigslist buy with a few replacement bits from my parts pile).
