Much like the crank arms, my #1 reason for choosing the Sinz brand chainring was price. The second was that it comes in this fancy red color. Normally priced at $16.50, I felt like I got a good deal.
I never planned on getting a new chainring, but I need this one to mount my crank arms. The new crank arms are not compatible with the stock chain ring.
Let's see the difference in crank arm length. It's not that much shorter. 170mm stock one on the bottom and new 155mm one on top. Though 15mm might not seem like a lot, remember that it's 15mm on each side. The total difference will be 30mm or to us Americans, 1.18".
I like the look of the RMP Components one. I'm not a big fan of showing off brand names and would much rather have a cleaner look than having it plastered with "KMX" on it. The shape is also a bit cleaner too - straight edges. It doesn't have that organic look with all the unnecessary curves.
I'm not a big fan of pink. The chain ring is starting to look more pink than it does red. We'll soon see how it looks on the trike. I want to install this ASAP to test the shorter crank arms, so I'll pop it on for a trial run and get a black chain ring if it ends up not looking right. This might've looked better if the bash ring (chain guard) was compatible.
Installation is pretty direct. 4mm bolts are needed for single chain ring setups. Longer ones are available for double or triple setups. The bolts come as a package. The steel ones I'll be using were about $5.99. The more expensive ones sell for $14 or so. The allen head screws right on. A flat head screwdriver is needed to tighten it from the other side.
Fully installed! Finally. Looks pretty good! Except that I was right about the color. It's off. It's pink. It's ugly. Do I want Schwalbe Big Apple tires more or a replacement chain ring? Hmm...
