Giant anthem

Today i decided to venture into the shock setup for the marshmallow...went out and purchased a rock shox pump (300 psi) 

 

googled shock setup...found fox website and did some reading and watched a few videos with a little humour.

 

Please feel free to correct me if you feel there is something i have done incorrectly as i am a newbie to this mtb thing.

 

fox site...2015 air shocks (float ctd/float x ctd)

 

Fox kashima shock model number CSKH

 

rule of thumb pressure setting your weight in pounds with kit...including lunch bars and bananas = 110 kg x by 2.20462 = 242.508 pounds 

 

Connected the pump to the shock...shock pressure = 170 psi...bit concerning as i watched the person load the shock to 210 psi at the Lbs...either the shock has lost the pressure or the gauge on the new pump not correct.

 

shock travel length = 44 mm 

suggested sag - 15 - 20 % 

 

15 % sag firm = 6.6 mm 

20 % sag plush = 8.8 mm 

 

Pumped the shock from 170 psi to 215 psi and sat on the bike...wait 10 seconds and moved the sag indicator o-ring up...climbed off the bike without bouncing around and measured the sag...10 mm.

 

the result...i need to pump the shock up a little more lets say to around 225 psi to to achieve a slightly firmer shock...and get a second opinion on the actual pressure or find out why it lost pressure ( it might be normal)...then i can set the trail adjust to 1 instead of 3 for a softer ride.

 

the other thing i need to do is move the rebound adjustment back 3 click clockwise...just before the ride i move the rebound 2 clicks anti clockwise ( from mid way 7 clicks)...feels like the rebound is too fast...so i am going to move it 3 clicks clockwise (8 clicks from start just past midway) and see how it rides.

I found this rather interesting...went for a test ride just to see if all was ok with the marshmallow (anthem) after it got washed.

 

Here the part that blows my mind...i have been trying to improve my time and endurance up a very steep hill just a few streets down from my house...using a road bike...without much luck...get home from my test ride on the marshmallow and find a kudo for a KOM...eeeish.

 

it seems that the bouncing on the marshmallow improves the performance/power rather than reduces it even on a tar road...did the climb in my best time ever...32 seconds..."analyse effort" 19.4 km/h 664 w (not sure how accurate it is...being strava) maybe i should try it on a hardtail mtb instead of a road bike ;)

LOL. That's VERY strange, cos there's no way an MTB is faster than a road bike up a tar road. Probably just a result of feeling good on the day and the different gearing you have on there...

 

Suspension action is beneficial on technical clibs cos it conforms to the surface and doesn't get skittled around as much as a hardtail would, therefore your tire has more traction and you are faster. 

 

There's nothing technical about a tar road climb, so you should be faster on your roadie all the time.

the guys in second and third place on the segment are both riding road bikes and i have tried on numerous occasions with my road bike to achieve this result...just to add fuel...my fastest speed on strava is on the marshmallow and not the road bike either on the same route...figue that one out.

 

The fella from the bike shop indicated that it could be because the road bike i ride is old and the technology of the anthem and gearing is better.

 

i still find this hard to believe...not only is the tyre pressure on the mtb much lower (2.6... which should result in more drag on the mtb...my road bike tyre pressure is 8 bar with skinny little wheels.

 

I have seen drastic improvements will fellow riders who change from their mtb to a road bike...in fact 1 in particular cant keep up if he rides a mtb bike with us...but if he rides his road bike...no problem.

You made an interesting point...handlebar width.

 

While setting up the road bike...the suggested width of handlebar for the road bike was 400 mm...feels very narrow in comparison...even when i stand and pedal...which i do a lot more of lately...battling to get use to them...in fact i am seriously considering fitting wider ones...just for better stability.

I've had the same thing on a hill in my valley. I set the KOM using my 1x9 rigid 26er. Needless to say this angered the local racing snakes and the KOM is no longer held by a 1x9 (9 speed!!! shock horror disgust) rigid 26er (26er!!! do they still even make those)  :D

I put it down to feeling strong that day and the gearing on the rigid just suited the climb better than the road bike.

I am also faster on climbs with my carbon hardtail, than I am on my entry level (full 105 9 speed) road bike. Also think it might be due to the gearing, since I have to push HARD on climbs with the road bike gearing, compared to the easier MTB gearing. Faster overall on the road bike though, but I have felt that the Road bike has made me stronger on the climbs as the gearing forces you to push hard. Took me quite a while to get used to the overall hardness (harder tyres and no suspension) of the road bike compared to the softer ride of the hardtail. 

 

Having said that, I do prefer the feel you get from a road bike while out of the saddle, compared to a MTB

i am sure the guys will be back to take the KOM...in fact i put the word out that i was this years leader up the hill on the weekend...by monday afternoon it was smashed by 5 seconds twice ;) ...i went out on the tuesday just to test ride...and found when i got back that i had the KOM...all in good sport...having fun with the fellas.

 

as you can see by my profile pic...i have a long way to go just loosing weight and even when i get skinny...my age will restrict my progress...i got a shock the other day when i entered a race to find i qualify for the old toppies group :(

Took ol daisy8 out for an afternoon stroll this afternoon...almost bust the KOM again ...if my shoe didnt unclip i believe i might have done it in 32 seconds...but had to settle for 34 seconds.

 

Ol daisy8 is a 3x8 edge sportif someone was throwing away....almost as old as i am [emoji12]...have a soft spot for this bike.

Is THAT your "road bike"!?

 

If so, no wonder. That's no road bike. That's an abomination

Please dont insult ol miss daisy8...she managed the segment in 34 seconds which put her right behind the 2015 model anthem x and 1 second in front of 2 hi tech road bikes ridden by 2 race snakes [emoji33]

 

To add to her list of achievements...over 1000km recorded on strava...including a 100 km strava 1 day challenge...but her best achievement...her total cost to date including purchase and maintenance is less than what it cost to replace a chain on a giant anthem [emoji482]

When you set sag on a CTD shock or fork it MUST be in open ( descend ) mode to measure the sag correctly. It helps to push the o rings up against the seal lip before you sit on the bike and compress the suspension.

 

Also, when you attach a shock pump, some of the air escapes to pressurise the flexible hose and gauge, so pressure is lost and reading will always be at least 5 to 10 psi lower than what the gauge showed when it was last pumped. You got a 40 psi loss - could be a leak or you lost more air than normal when attaching the pump.
