Dura ace 9000 52-36 172.5

Thinking about swapping my dura ace chainset for a compact as I don’t have the oomph to pedal this one!! It’s a 52-36 172.5 in fantastic condition with no heel rub
Came on a bike I bought recently second hand but the owner had run a compact ultegra for training. The dura ace was put back on to sell the bike
I’d need a dura ace compact in equal condition - I’m fussy, I don’t like heel rub at all and want something with low miles
Let me know if you have anything suitable
I’m in bristol and would prefer to meet up rather than post 👍🏻👍🏻

    Why don't you just change the chainrings to compact?

    Yes, it will be the exact same crank and bb. Sometimes a complete crankset comes in cheaper, mind you.

    Other option is just get a bigger cassette at the back. Unless you are daft enough to buy a DA cassette, it will be by far the cheapest option.

    Change chain rings, take a couple of links out of chain, lower mech.

    Ots the cost of those outer chain rings that is the issue. They are stupidly over engineered, and so stupidly expensive.

    Personally I think machining or stamping, or a combination, should be sufficient for making a chain ring, but shimano do all of that, then glue two bits together then bung a few pins in the back and charge 3 figures for a consumable.

    Msp £165. On sale at sigma sports for £129. Add another £40 for the inner ring.

    Alternatively, buy two or three 105 12-28 or 12-30 cassettes, a lock ring tool and a chain whip, and cycle happily for about 20000km for the same price you'd have to pay for cassettes anyway.

    I’m trying not to be out of pocket as I’ve just bought the bike so ideally looking for a swap
    All good suggestions though, I may end up just buying one and selling mine when the compact arrives

    Agree 100% its stupid ridic expensive but options:

    1. bite the bullet
    2. buy and then sell current chainrings
    3. TA specialities
    4. Exactly as you say
    5. Carbon ones for max bling
    6. Buy a different make

    I'd hunt for a replacement chainset, and then sell this on - it appears to be in good condition, so I think in the current climate would command a decent amount of cash.

    The flip side is trying to find a 50/34 in decent condition, and the potential you would end up having to replace the chainrings in the not too distant future anyway.

    Here's a thought - have you considered buying a relatively affordable inner 34T chainring for your crankset, and running it as a 52/34?

    It is outside of the shimano 'recommended' range, but I run a 53/36 with absolutely no issues.

    Another alternative would be if you have ever wanted to go for the Absolute Black chainrings, you could use this as an upgrade opportunity, and then sell the stock ones on, probably for a decent amount of money.

    The absolute black do look like a contender, decent price too👍🏻

    I like the 11 30 cassette idea. Or 11 32 depending what's on. Took me a while to get on to 52 36 with 11 28 on back(coming from 50 34), i just put 11 30 on and I do notice the difference. Least hassle and less money spent.

    Will the rear mech handle a 32 sprocket.

    Not sure it’ll handle 30 or 32 cassette ring (11-28 currently)
    I’ll check tomorrow but looks like a short cage to me
    Best pic I’ve got atm

    If your rear mech copes (a medium definitely will), get an 11-34 cassette?

    ~£60 before loyalty discount and cashback https://www.merlincycles.com/shimano-105-cs-r7000-cassette-11-speed-117086.html

    With 32mm rear tyre, that will give approx 28.6 to 127.6 gear inches range, according to https://www.sheldonbrown.com/gear-calc.html

    With my 34/50 compact, this cassette gives 27 to 122.7 range. I've been using 11-34s for a few years now and they've been a revelation, I like the challenge of hills even though I'm the wrong side of 80Kg, so when I'm dead the 34/34 is very welcome! Plus the sprocket sizes give me more practical gears for climbing that are larger than ~16T, compared to the 11-32.

    No idea if it's the cheapest source, but GS 105 mech is ~£37 with SALE15 code, bit of topcashback too. https://www.probikekit.co.uk/bicycle-derailleurs/shimano-105-r7000-rear-derailleur/11746883.html?variation=11746885

    I have short cage rear mech and a 30 sprocket.
    However I have just realised mines a 9100 series.

    Wolftooth may well help with any cassette shenanigsans

    Found a compact for £150, gonna go that way for now so I’ll probably put the 52-36 up for sale here in a couple weeks - or just keep it for a spare not sure yet, see what the compact looks like first
    Had my first ride on it today and while it’s fast on the flats it’s brutal (for me) on the climbs !! 😂
    Thanks for the replies, some good info there 👍🏻
