Going from 165 to 170 cranks

My new frame has a fair bit of ground clearance (about 10inches)
ive bought myself some new (second hand) 170m cranks as im less worried about pedal strike.
will i notice a 5mm difference when riding normally/spinning down hills etc or is it too small a difference to notice?

For about a day and then you will forget.

why don't you put it on and see what happen?

I find it's a blessing, somehow pedalling is much easier, I suppose if you're pretty tall (at least 6"), you'll probably find it to be better.

yeah im 6 2" so thats why i thought id be ok
come to think of it my geared bike that doesnt get much use anymore has 175mm arms and i cant tell much difference. i suppose you get more leverage with longer crank arms (someone who knows physics stuff correct me if im wrong)

Agree, 5mm won't be noticeable after a day. It will require a bike fit change though as you will need to lower saddle by approx 5mm to get same distance from pedal to seat so you will be sat lower on the bike (although I would prefer that to being 5mm higher)

I have 182.5 so 170 should be no issue.

:-o

190mm ftw

My crank is bigger than your crank..

Is that a crank in your pocket or are you just happy to see me?

Is that a crank in your pocket and my girlfriend Mal was happy to see you?

you are such a tease, its not the size but the way you use it ;o))

and you've never had issues with pedal strike?

Or you could go for 130s as per Mike Burrows experiment. Allows use of higher RPM with lower gearing to get same speed. Sounds good but wouldn't want to deal with a saddle being 40mm higher as that would completely screw by bike fit!

He forgot to mention that he has to dismount and walk around any corners.

Pedal strike fear

Its a very real condition. You can take pills for that.

A few cracked ribs later, yes, I do have pedal strike fear. its not fun. shallow cranks ftw.

pedal strike usually solved by riding clipless, my bike used to have massive pedal strike, until I went clipless, and were able to use 170mm cranks.

of course that's not to says that clipless will defintely prevent it.

A lot to do with BB height too, of course. If using a track frame then much less chance of it.

Don't ride fixed on that bike so on a heavy corner I stop peddaling. Never have suffured with pedal strike but in the past have had pedal/bike jump.

I prefer my cranks emotionally deep.

shit, I mistook pedal strike with toe overlap, whoop!

crankers

I have 165s on the fixed, 170s on the commuter, and am getting 175s for the SS off roader. You can feel the difference, but for me different types of riding are best done with different crank lengths (to a point). As long as you have the BB clearance 170s sound great for a person of your height riding fixed.

I've just gone from 165 to 170 on a road frame and had my first ever pedal strike whilst manouevering wildly when drunk.

I didn't come off, but now the fear stalks me like a wild beast. I bomb along the straights, but then potter round the corners like an old lady.

although you meant something else with the original comment - i had the opposite issue, i went from Keo Look clipless, and used to get toeverlap on my fuji, now im with MKS clips (L) and pedals there is no toeverlap.

Im on 170mm cranks and I've nver had pedal strike..
