I got a trixie for my birthday as a tool to carry as I ride (nice to fix loose stuff, lockring, saddle, bars, etc) and here is a review of my first impressions.

Size, the trixie is a very managable size to carry about. it is about 7.5 inches long and 1.5 inches wide and .19 inches thick. The thickness impressed me the most. I initially thought that it would bend under too much stress, but is very thick. I don't have a scale to measure mass or weight, but it is a very solidly built tool. It also fits quite nicely in one of the front pouches of my Chrome bag, which is a plus.

Here i have size compare to a USA dollar, as well as thickness shown with my calipers.





tools: The 15mm box end wrench is great. A wonderful replacement for those of you carrying around PB wrenches. It is thin, long enough to give you the torque you need to tighten down the wheels and gives an _ok_ feel. Keep in mind that you will be holding the lockring part, so its not totally ergonomically good. The 5mm hex is a nice tool too. Provides ample length to torque on seatpost/saddle/headsets/bars. The 8/9/10mm box end wrenches seem a little difficult to use. My bike does not have any use for them, but I imagine using the 8mm might slide a bit and does not looks ideal for using. also these provide less torque than then 15mm due to the placement (t=f(d)) Lockring tool. Again, a great tool. Length allows for proper torquing (easly get the 40n*m required, and I'm not extremely strong) Chainwhip: I didn't have any spare lengths of chain to make one. It doesnt come with chain, you have to provide it yourself. Bottle opener: srsly, why a bottle opener. A larger hex for tightening cranks and/or a spoke wrench would be much more useful. Most stuff that is good for you has twist off anyway

Overall, I am very pleased. As an emergency tool, it really can't be beaten. The slim design is easy to carry, thin, yet seems durable enough + the lifetime warranty. It lacks a few things that I would like (mainly a larger hex for cranks, as I've had one go loose on me before) but seems to have all of the things to rescue something gone wrong. I'd give a grade of 9/10

I got one too, and I like it. It seems well made, but I am not sure it is worth $30. $15 or $20 I think is more appropriate.

where would one attach a chain to make it a chainwhip?

Do you need a chainwhip when you can Rotafix?

yes!

That small hole in the second picture is where the chain is supposed to go for the whip.

I'm sure this thing will sell, but I just don't get it. I'd rather just use real tools.

Nice review, I've been thinking of getting one of these for a one-stop, basic tool to throw in my bag.

I have one too and I really like it. For those saying it's overpriced- Where can you get a lockring tool, a 15mm wrench, an 8, 9, and 10mm wrench, a 5mm allen wrench, and a beer opener (all of which combined weigh and take up the space that is about the same as just the 15mm wrench) for $30?Great tool.
