Cheers IBR, that should help me plenty - I'll try and sort it out tomorrow, keen to hopefully get it and the pedals ordered asap.ibr17xvii said:Pic of my 4iiii PM - excuse the towel underneath! The bike is on the turbo & the matt I use is black so the crank / sensor wouldn't show up very well.
FYI from the edge of the PM sensor to the end of my crank at the pedal (175mm) is approx 9cm.
I bought it home saturday, chucked an old quilt cover over it, and haven't looked at it since
In reality I'll be trying to get all the changes made by spring next year, but will try and get a ride out on it if the weather decides to be reasonable again this year.......
If not I'll just have to take measurement comparisons between it, as stands, the Foil and the CR1 to figure out what size bars/stem I need.
P.S Just read why the towel is there - genius, and that is going the extra mile, thankyou

Oooh, just spotted the pedals too - fine choice sir!
Mine has 172.5 cranks, and looks to my inexpert eye that the sensor is approx 3cm long, so on your crank the other end of the sensor is at about 12cm from the ledal end of the crank, which means ~5.5cm from the BB end of the crank.Felt F70 05 (Turbo)

Re pedals - if its all out weight savings, surely those stupid light Speedplay are required?
plus its an excuse for some fancy dan martin fandango new shoes for the cleats
otherwise its just a botchy half job, innit....The camera down the willy isn't anything like as bad as it sounds.

Pedals are "only" the Cromo axles rather than what you are eyeing up! Changed to Look a few years ago & they've never given me any grief. Prefer them to SPD-SL but that's just me.
I would say you're about right. Unless you've got peculiar chainstays you'll be fine.
As I was in doubt not gonna lie I ordered the crank from Wiggle 1st to see if it would fit then sent it back & ordered it from Merlin cos it was cheaper.1 -

Or Exustar*, if you want to keep the Look KEO system.

They're smart.
I'd be seriously tempted with those if was in the market for a new pair.0 -
Good write up here and yup, if they are like the far cheaper versions I have, ridiculously solid once you're clipped.
hmmmm, i could be tempted to treat myself..

If it were me I would take out alternate spokes and alternate balls from each bearing race.1

I'm working on reducing body weight. Little fingers and little toes could easily be removed. Teeth are overrated (and heavy) and is a nose really necessary?0

Looks good on paper, but they don't ship to the uk cos of idiotic decisions (not by them I hasten to add), and they have gold on themMattFalle said:Saw these on Bike 24 - lighter than Look by a chunk and half the price

I found them for £137 delivered from starbike, but with all the extra costs that would kick in at ~£190 - and I can get the Looks for £210 from pbk, less cashback, so probably £205.
Weight wise the Looks are 180g, these are 176g, so pretty nip and tuck.
I have £9.99 exustar pedals on my turbo bike if anyone remembers that deal from way back when on the bargains thread, can't recall the retailer now, maybe Merlin or something - they are still going strong.
I will have a look at speedplay, but I'm pretty happy with Look pedals like @ibr17xviiFelt F70 05 (Turbo)

.. its choosing pedals that cost 3 x more than a pair from the same brand that perform that same function just so that you can save 0.8 secs on your local hill on Strava.MattFalle said:

You don't go down the saving weight rabbit hole (copyright GPLama) if you want to save money.

So back on topic - I have carried out the 4iiiiii template and AAA battery test, and all looks pretty darned healthy, clearance looks good to my mind, don't see any issues.
That will be really nice to have a subtle way of measuring left hand power with no pods to deal with (I realise not all power pedals have pods I hasten to add)
So that will be ordered shortly - the pedals above do look very light, but currently not available in the UK, and look to be mega money, and I think I'd be happier with the Look options, so they will be ordered shortly as well.
Spokesman currently getting a quote and lead time (No hurry from me) for the hubs from Tune, so will be interesting to see what that ends up being, weight and cost wise.
Looking at a 22mm internal rim width, and running 28mm tyres on it - online calculators tell me that should be fine, though any less would leave me on dodgy ground.
Realise I will need a replacement WCS clamp that will accept carbon rails, but think I might have a spare pair from when a bolt broke previously (12nm!) and Wiggle replaced it under warranty.Felt F70 05 (Turbo)

19mm tyres are a lot lighter.1
-
I'd go 23mm - 28s are going to weigh more and 23s are - shock horror - perfectly fine.
seems weird to add weight when not needed to..The camera down the willy isn't anything like as bad as it sounds.

If I remember rightly, Specialused Turbo Cotton for tgese sorta shenanigans?.

The wider rims are lighter, but you have to use wider tyres.
I was always planning to use 25s with the option of going up to 28s.
So the 28mm tyres will mean I can run it at lower pressure, have a more comfy ride and benefit from the lighter 30mm deep X 22mm internal width rims.
In my opinion, and for this bike, that combination seems to be the best compromise based on what is available.
They will be paired with GP5000s which size up a little small anyway, and latex tubes.Felt F70 05 (Turbo)

Contis are 65g per tyre heavier, so 130g overall which is quite a chunk tbh....
(those weights are based on just a quick Google btw)
Or go 26mm Specialised and save an extra 20g making a nice round 150g which is not to be sniffed at.....The camera down the willy isn't anything like as bad as it sounds.
