Added some bling! Trying out an oval chainring (30T) but stripped 2 of the 3 torx bolts when torqueing them to 9Nm. So I guess I'll be sticking with the oval chainring for a while. 🤣
Rode around the block (flat road) and didn't feel a difference. Neither good nor bad. Can't wait to try it on techy climbs.

interesting - the oval is not 90 degrees to the crank?
or is that just a camera thing?
maybe it shouldn't be now that i think about it....

The peak of the Oval is at the midpoint of your downstroke. The end of the pedalstroke is in line with the seat tube, not straight to the ground.
that is kinda what i was thinking - it is over before it is straight down......now i know why!

Took the bike out at Graham Hills today and honestly couldn't tell a difference with the oval chainring. The bike felt great and efficient when climbing but I've changed other parts / service that might have contributed to its well being. So I can't say for sure it was from the oval chainring. I'd have to chalk up any perceived advantage(s) of the oval chainring to placebo, for me any way.
But the sum of all the parts made the bike felt better than ever - 35mm rise bar, 155mm cranks, oval chainring, & lubed all things. Very happy and appreciate the bike. 👍

There's may be some minor difference in operation, but generally there are two things to consider:
Do the brakes use the same hose?
Do the brake levers have the same power profile (ie: cam in the lever).
If both are satisfied, it's probably going to work fine...but you'll never get confirmation from Shimano, since they are not from the same generation.

as long as the hose matches up and seals you will get brake activation, the question is if they will activate the same (throw, strength ect) when you use them.
the other thing to consider is the size of the master cylinder (lever) diameter and travel which affects how much fluid they push/pressure they can build

Haven't done it myself but what could possibly go wrong?
I would do it

With regards to the oval chainring... I went to the local trails (Alpine) yesterday and I noticed that the rear has more grip. Where I would usually spin the rear tire loose on techy climbs, I find the rear just rides over the rocks. This is with rear DHRII that's probably due for replacement.
Summary: It feels as if I went from a torsen LSD to a cluth-type LSD with the oval chainring.

I traded for this jawn last week or so. I have some items coming to get it back to the way I had my old El Mar set up. I do like it's a SS specific frame... hope to have it out next Sunday.

Wholeheartedly approve! May I suggest a carbon firestarter fork as an upgrade?

I do plan on putting a carbon fork on it down the road.

Nice, but why not put the nice, new cassette on one of your outside bikes, and move the used outdoor bike cassette to the inside bike? Unlesss maybe you got a good deal on a new cassette with gearing that you would not use on one of your outdoor bikes...

indoor/outdoor bike is the same one right now. I have a spare wheel i swap for the trainer and use the same gearing.
I got new (to me) wheels about 2 months ago that cassette was also new when I got them so no real difference except outdoor wheel is Ultegra and this one is 105. Plus i did get a great deal on this for cheap.

With 5-inch fat tires, an oval ring feels more like a Detroit.
