it always comes to what handlebar drop you are looking for

what is your saddle height ? - c bb to top of saddle along the seatpost

711mm c - t of the saddle, and I'm not particularly worried about seatpost showing, i know most guys like a lot of seat post showing.

i have a saddle height of 71,6

on my R3, with the lowest possible headset bearingcover (8mm), no spacer i get to a handlebar drop of 7 and a bit cms

do you want your handlebar lower, you need to choose one size down

for the c59, do not go larger than 53 (traditional)

Quick help needed from the weight weenie collective, My dad has trouble with his knees and as such wants to replicate his bike across his fleet.He's just purchased a house in majorca so can't afford to buy a brand new super six Evo so is looking for second hand, but I wondered if people knew of any frames that share the same geometry and are DI2 Compatible
any ideas?
many thanks
Bruce

Hi Bruce,

This company rent Cannondale bikes out to riders in the Canary Islands for 3 to 6 months. They then sell them off at ultra cheap prices in comparison to new prices. they told me they completely clad the frame in vynil so that when they sell them on they look new.

It might be worth contacting them to see if they have one for sale that fits your dad.

A very old post I read a while ago in WW. You could take a look.

Looking at a second hand Caad5 size 54cm road frame online. Can anybody who has one tell me the measurement from bottom bracket centre to the top of the seat tube? May not seem important but I have quite a low saddle height and would like to know how much seat post will be on show.

Thanks.

Buying a new S works tarmac, but wanting to go a bit racier than normal and save some weight from the frame.

is it ok if when turning the wheel the foot is at 3 o clock and can hit the wheel. I think its ok as if you turn that sharply then your foot should be at 6 and 12, however I thought i'd best check with some wiser minds.

Cheers

Hi guys,

Can someone who uses that 25-30degree rule post a picture of their leg extension whilst pedaling? Just wondering what it looks like asthetically.

Thanks

I was hoping to receive some assistance on properly sizing a new Focus Izalco Max frame. I will be going from a Fuji Altamira SL S/M(http://www.fujibikes.com/bike/details/altamira-sl#bk_desc_tab1 and presently I believe the Izalco Max XS(http://www.focus-bikes.com/us/en/bikes/2014/road/izalco-max/izalco-max-10.html#chapter-3) My current bike has the following measurements, and is quite comfortable. I'm ~171cm tall.

Final Bike Measurements:
Current Bike and Size: Fuji Altamira 2013 Small
Saddle Height: 717mm
Grip Reach (nose of saddle to center or grip): 61cm
Arm pad reach (nose of saddle to back of arm pad):
Saddle fore and aft on rails: 6mm Aft
Saddle: Selle Italia Evolution
saddle setback: 55mm setback
Stem: 90mm - 7
Knee over Pedal Spindle: 0
Drop: 75mm drop to handlebar
Crank Length: 170

I'm having a bit of trouble imagining the difference in stack/reach between the two frames. I presume the stack difference could be the result of slopier top tube, and I take it that the Focus would be a bit more stretched out and aggressive?

Thanks for any help.

The fuji is 528 / 370 and the focus is 520/384 in a small or 515 / 379 in zs

So, with the focus in a small you'd need to add a 8mm spacer and an 8cm stem for the same fit approximately. For the xs you'd need 13mm in spacers and be I between stems because spacers slightly effect reach

Thanks. So for the XS the ideal stem would be between 80-90 mm?

Best.

A little toe overlap is no big deal, you'll never be turning that sharply anywhere but a parking lot or while track standing.
