Remove the crud catcher, the chain device and the bar ends...
Those are painful items to see on such an otherwise beautiful bike.
Light weight set of wheels would be the best upgrade.
Those cranks are not hyper light either.
What is the budget and what is the current weight?

Unfortunately budget is minimal as most was blown on building the thing.

Point taken re: chain device.

Bar ends stay as I love them and Crud Catcher is ugly, but stays until I can afford some new cycling glasses (it's there to protect my eyes, not my clothes).

I'm hoping to err on the side of light weight strength and durability rather than extreme super light (hence the ti componentry and minimal use of carbon).

Weight unknown at present but will find out...

Cheers

With respect to the chain device, try using a simpler and lighter chain catcher that mounts on the seat tube below the FD and prevents the chain from dropping off the granny ring down onto the BB shell. Deda has a model called the Dog Fang. They are usually about 20-30 grams and worth every penny spent on them. I use them on cross and road bikes and they function perfectly.

OK, on a limited budget, take a look at lighter tires to remove some rotational weight. But quite honestly, unless the budget allows some big items like wheels or cranks, I would leave it as is. Great looking bike and solid build. I bet it is lighter than you think.

Thanks man!

Will def check out the dog fang. Part of the reason I've held on to the DCD is that the SRAM XO trigger shifter doesn't allow for micro-indexing so I have to set my front mech up in an odd way to avoid chain rub at the extremes. This results in the chain falling off quite frequently. Should all be sorted once I fit the XO gripshift that's coming in the post.

Thanks for the complements and yeah- compared to my last bike (Marin Pine mountain bought new and ridden since 1995!) it is VERY light!

I fancy some Fox Shocks next year so was wanting to be as light as possible if additional weight lies ahead...

1.) get rid of the front fender thing
2.) get rid of that chain device on the rear seat stay
3.) do you really need bar ends that big? Or even bar ends at all?
4.) nothing wrong with the wheels, get some lighter tires and lighter tubes
5.) don't use a valve cap on the tube
6.) sell your brakes on ebay and get some lighter ones
7.) foam grips

I switched my SRAM front derailleur to an XTR, which is MUCH lighter. I found it on Ebay.

Nice looking bike! (I have a sola too.)

Heh heh! You're a bit late- I did as you suggest 2 months ago! Thanks for the tip and compliment though.

Current spec has changed to include:
- 2009 Fox RLC 120mm with lockout
- Kent Erickson seatpost
- KMC SL9 chain
- Titec Hellios riser
- Straightline titanium end-plugs
- Shimano XTR front mech
- SRAM X-O gripshift for front mech

Current Shopping list:
- 2009 Hope mini mono pros
- White Specialized Phenom SL saddle
- White Ozriders grips

Should be complete for the time being after that.

Hey tkehler, got a photo of your sola with spec? I would be interested to compare notes.

I'll post mine up again (probably in the Gallery section) when I've finished the planned alterations...
