upgraded CB - Ti spindle

Gobi XM Ti railing

might be changing to a lighter headset to Mortop. Weight 50g lesser.

considering a Olympic Alpine rims, FOX F-SERIES RLC 120mm 2010 = 1.47kg. Same weight as SID RLT Ti

what montain bike Aug 2010 issue

I bought a Yeti ARC frame and was thinking of moving to hardtail reasons are lighter, reduce risk of injure but before I build it accidents happened to me and I broke my collar bone. Doctor and chinese medical hall said I need to rest up to 3 months.

15 August I have fully transferred all my parts over from AM to Hardtail. Will be cutting down on kiara and wanna do more road and cross country with PCC and HASH.


Below are some R and D of how to reduce further weight from my YETI.

Client Portfolio

Finally I got some of my work online. You can access to my client website to view the photo here.

wide test - the diff between 20mm and 24mm

I need to get a wide prime lens so I did a simple compare between 20mm and 24mm prime. Only these two I can afford and anything below 20mm is totally out of my budget.

Photos below are some image sharpness test @ the center

Nikon 35mm f2D @ f2.8

Nikon 24mm f2.8AI @ f2.8

Nikon 20mm f2.8D @ f2.8


verdict: Nikon 35mm f2D is the sharpest


Photos below are some image sharpness test @ the center and corner between Nikon 20mm f2.8D and 24mm f2.8D

Corner test

Center test

verdict: no obvious sign of different between these two lenses on center and corner!
