Very similar to my setup !!

I've got 172.5 arms (stripped) with 50/34 Praxis rings, the Qman alloy spider but have steel chainring bolts atm, as that's all I could get locally in stock :evil: . The alloy ones I had were too short, but will be sorted.

Will weigh all my bits to compare !!

Specialized Allez in gold :)

I am not that strong of a rider. I don't use my 50/11 combo often so I thought I give this a try. Is only a 4% difference anyways.

I got steel chairing bolts too. I rather gain a few grams on the bolts for better durability.

Alloy chainring bolts are durable and will save quite a few grams

I use a 48/34 CarbonTi on the hills. Not the best shifting experience but works when the total ascend is 4-5k ft...

The catch pin on the big Praxis ring is too long. It interfer with the crank arm.

I filed it down and it now clears.

No hills where you live? Seems odd to me to ditch the 50 but keep the 36 :noidea:

Oh I'm totally with you. I ride 50/34 with an 11-23 cassette. I ride most flat ground and I like the tight spacing. Completed crankset looks great!

Need a S-Works Torx T45 tool... Does anyone know if:
1. Where can I buy the tool that ships to USA.
2. Any CONFIRMED compatible none Specialized tool? Craftsman?


The one that I have is too thick except for the tip... WTF Specialized!!!

I rather have the tool to keep than going to my LBS every time I need to get my crank on and off.

I may have a spare one that I could part with. I'm in Oz, so there would be some shipping.

Mind you, I've seen them on ebay too for about USD$16 + shipping
