rgliniany

and apologies..... had my mind on something else when i said chainset........ groupset was the word i was aiming for :roll: probably just a friday afternoon production run

I don't think Tiagra is that good really - It might be the same place in the list as Deore, but it's not as good.

Sounds like it could do with a really good clean and lube though, I don't think roadies are quite so tolerant of crap weather. Remember that if it's new the cables will be the crappest of the crap to save the manufacturer money.

Good Luck with it...

Flight Deck was Shimano's computer, having the decal just indicates compatibility, nowt else. Tiagra is 10 speed now, as Yeeha has said, so it's the latest generation!

The brakes I really did find to be totally shite I must say! Mine seized solid after 6 months or so, replaced with 105s, which have the added advantage of using cartridge pads so it's quicker to change. Still don't stop me anywhere near as well as my Dura Ace ones though, but marginally less terrifying.

Be bloody discussing colourways next.

njee20

There will be no such discussion.

On the road white is fastest, followed closely by red, then black.

Mine is silver with blue splatter and cream stays and forks with yellow splatter - awesome early 80's?
Explains why I am so slow.

njee20

Yep, cream actually slows you down compared to no paint.

Mine's white
The brakes are not Tiagra, they're some no-name things, possibly Bontrqager, or Trek's own?
They have cartridge pads, but no toe adjustment, and they're actually pretty good.

So my white with red and black detail is not quite as quick as if I just strip the detailing off? If only I'd known that earlier I could have stopped all this training shit!

YeehaaMcgee

Njee's right you know, my mountain bike is black, and that definitely isn't as quick on the road as the white roadie.

njee20

Correct, but white must be kept clean. Doubly so for bar tape. White bar tape is fastest, but dirty white bar tape is actually slower than black, confusingly.

It's a bloody minefield all this aero stuff I tells ya.

Roadies are tossers eh.

I agree, which is why I bought up this subject in the crudcatcher, where it belongs, since it's just crap.

Have you sorted the front mech? My 9 speed Tiagra one got like that and it was one of the utterly inaccessible pivot points that was seizing up. Managed to free it off by squirting GT85 at it then stuck some dry lube in it and it's been fine since. Only issue was that I had to take the mech off to get at it properly.

I did basically exactly that, but managed to get at it in situ, with a straw nozzle thing on the can.
Then just kept cycling the mech over and over and over and over, and it's been ok for another 100 miles or so.
