u need to try di2 first. it's not for everybody. just fiddle around with the shifter and then u can decide. btw, after i've tried it, di2's not for me.

i've found a new love...

R5CA is now gone and the new RCA is in... lighter and equally as expensive... USD10k...and only 345 will be made...

Cervelo claims to find the great compromise in the new Rca

$10,000 Cervélo RCA frame that weighs 667g - first look and ride


new nickel coated carbon steerer fork...


new squoval shape and new resin material...

the books are to be taken lightly... they are liars in the first place after all... what makes their words in the book credible now?

as for the 25 vs 23 debate... i guess the only answer i can give is to try it out yourself... it works for some people and doesn't for others... as for the 25mm, you don't pump the same pressure as your 23s... you run it slightly lower and usually around 90psi depending on your weight... i have no issues with 90psi and it still holds up quite well in terms of rolling resistance and comfort...

i like 25s myself and recently, due to my 25 running down to the kevlar and multiple successive punctures... i switched back to 23 for a short period of time as i have not yet procured a replacement... riding up inclines feels a bit like the tires squishing around more than the 25 although running at higher pressures of 100-105psi...but then again, my weight could be playing a factor in how it responded for me...other factors also could be the tire layup and the rubber compound... if you are comparing the same tires of different widths, then your feel would be more validated on the ride quality of both sizes... different tires more less gives a not so definitive answer...

threads or no thread is a question of full slick for dry roads vs. a bit of all weather for the rainy days... with those thread depths, it might not help much but it is at least there to help dissipate water under the tire... unless you lean into corners like motogp riders... i'd worry about the compound more as that is the magic thing that gives you grip...not so much the threads...

your bike shop can order them in but you have to let them know way in advance as i think they ship it together with their own shipment...

don't think anyone keep stock of the SRAM quarq power meters....quarq cranks are usually considered separate purchases.. i believe they can work out a deal for you if you want to purchase an entire Red group... they will just deduct off the Red cranks and put in the cost for the quarq cranks...

i would suggest not to get it first as you are not sure what frame you will be running on in future... for now, you will most likely use GXP... but future, it might be BB30 or even OSBB in future...unless you can live with sticking a GXP into a BB30 frame via adaptors... i would say if power meters is among your consideration... you might as well hold everything off and get it all done in one shot when you purchase the frame and group together...the quarq cranks won't be cheap, mind you... no less than RM4k by my guestimation..

i would think it is better not to get the power meter now irregardless of what you do... if you get the frame first, then the power meter is OK...

the best scenario now since you can't wait for everything to come together is get the full Red group which i assume you will transfer to your eventual frame watever it is, but stick with a GXP crank first on the scultura... this will waste you some money by buying the GXP crank and then later the quarq crank...

but, reason is your scultura does not have BB30 and neither is there such a thing as converting to BB30... so, BB30 is out of the question now and you are still not sure of your future frame... best is to get a normal GXP crank which you can write off or sell it when you get your eventual frame and get the quarq crank then...at least this way you can maximize the crank and get the right one for your future frame which might have BB30 or OSBB which i believe you want to maximize on the axle stiffness rather than sticking to a weaker GXP Quarq crank that you will transfer over, right?

My logic is simple, it is better to sacrifice a cheaper GXP Red crank rather than a crank which you have to use converter adapters later on which you might not be 100% happy because you could not fully utilize your frame's benefits and neither do you have money to reinvest on the right quarq crank then...

with my limited knowledge on power products... i am not sure if the pedal based ones are good... and are they even out yet? i know for sure they have one thing that neither quarq, powertap or srm could do which is to measure left and right foot power outputs.. i believe quarq also has a similar feature called powerbalance which estimates your left and right foot power output, but it would not be as accurate...

as far as using power meter goes... i am not sure if it would really benefit us... i believe SRM is better than quarq but the problem being SRM is a pain where even the battery change has to go back to the vendor... KL would be creative mill in my friends case...so does calibration.. quarq allows the user to perform battery changes (CR2032) and also vector calibration themselves...not sure of how important is this criteria...

as for usage, power meter would give better readings on perceived efforts over the standard HRM as little things like sickness or health issues can mess up HR readings...while power meters give an additional dimension by letting you gauge your effort by logged power readings against your HR...in my view, unless you are really into competition and have very strict training regiments like riding intervals and riding full all out for extended duration to log your data... the data extracted might not make much sense to you and neither does it help improve your levels...the data captured can be very mind boggling to look at if you just ride normally and within your limits... you have to know how to record and utilize the data captured to make full use of it.. that or you have a trainer...

speaking from a friend's experience on owning a complete SRM.. i am not sure about using garmin and other Ant+ capable products... he also thought initially that the SRM would help him on competing in endurance events.. but later only did he find out that his readings is also quite inconsistent where some days he thought he was doing well but the logs shows that he was not comparing to other recorded logs and vice versa...

so, it is very complex and takes a lot of understanding, monitoring, analysis and comparing between logged rides if you really want to use it as a training tool... having the SRM power control also helps as i understand that there are some on the fly analysis which units like Garmin can't perform... Garmin only shows some recordings from the captured data and some additional functions if i am not wrong...it is one of the things i do not plan to have as i could not fathom it and neither do i want to complicate my life as i am just a leisure rider..

in terms of the software... i believe the SRM software is also providing much better functions that cater to serious riders.. which is why it is the choice of the pros...

p/s...also too far out of my budgets...

If i don do anything, will it have any long term effect to the wheel?

rodalink... can't think of any other place having from 105 to dura ace on the racks for show

malaysian license can't work over there?
