Title: Crank set help
Post by: stupops on January 30, 2015, 08:27 PM: Hi Guys
just need some help. I have a 26' SE racing quadangle. its got American bb and a three piece 180mm crank with a 19mm spindle. will a european crank set fit it? or do i have to have the entire thing replaced. trying to make it as light and quick as possible and i am pretty sure the stock crankset is not up to much. thanks chaps.

Bung up some pictures of your bike and people might be able to suggest bits to change for you?

Lighter kevlar tyres?
New lighter wheel set?

halo spokes
halo clickster freewheel
thickslick tyers
se slayer hubs
avid speed 7 calipers and levers
DMR flat mag pedals
Richy seatpost
ODI lock on grips

it looks like fab (to me anyway) and rides lovely. although replacing cranks a bb is a right job. i fear i am just spending money for no good reason!!!

Post by: pickle on February 02, 2015, 07:32 AM: only two things wrong with that.

1. The seat angle is a bit wrong

2. THOSE BARS! they need to be inline with the forks, it's not an old school bike with shyte geometry :daumenhoch:

If you need the bars in that position to ride comfortably then you have the wrong size frame.

Or the seat too far forward...

Just needs a little fettling and fitting and will look cool :daumenhoch:

Looks set up for cruisin, ie, sitting on the seat leaning forward, putting the seat up and moving the bars back will give a similar postition.

Coventional bike fitting suggests you sit on the seat and balls of feet on pedals legs should be slightly bent with knees over the pedals, much easier on the knees for us old farts.

Profile cranks would look good on it.

Right. I am being a total numpty here. I have never had a threadless headset before. My last bike was a mongoose decade in the 90's!!
I have moved the bars back so that they are following the angle of the forks. Now when I ride it they bars feel way to low (I am 6ft 1). I just tried to raise the headset and realised that I cant really as the stem is attached to the forks and there is nothing to play with. do i need new forks with a longer bit that goes through the tube on the frame? thanks guys.

Post by: VOIVOD on March 24, 2015, 01:59 PM: :) Yep-looks like the steerer tube on your forks is too short to raise the stem any higher.Try taller bars and/or a riser stem.
