Hi,
Nice Klein! I like the white flite and campag stuff. It would look nice with some silver campag Stheno rims.
I run a 22" with the euclid brakes and the rear ones do catch your legs a bit. A 20" size is better in tight singletrack but the 22" is a lot more upright and more comfy. The 20" looks much neater.
Be carefull to use a very strong / rigid seatpost as the seat tube clamp area cracks easily. Mine has been cracked for many years but now looks to be spreading. I am going to try using a thick walled Shannon seatpost and hope that this may help?
I have also started to put one drop of chainlube at the rear cable exit point on my other klein in the hope that it will stop sweat from penetrating between the paint and aluminium and making the paint go all bubbly
I look forward to seeing your next Klein builds!
