Which Groupset?

i thought everyone knew that friction bra ends were the way forward

Been there, done that. No fanks.

rogan, you want a 34-32 gear?

Its going to be on a all-surface road bike, 35c clearances, will 34 28 be enough?

Subjective. I prefer 6700 over all the previous generations.

The problem (and as said Shimano acknowledged) is that running the cable run under tape for shifting was comprised if the bend radius of the cable following the bar was too tight ..

No idea, depends on the size of the hills and the size of your thighs I would imagine!

You need 30+ if you are using a non compact chainset, but why not go compact instead. Also I learned that you went canti instead of disc .. WHY!?

You said ergonomics not shifting performance.

I agree the shifting isn't quite as snappy as my 7800 DA but that isn't exactly a fair comparison. It still blows away most options. As for braking, it's still better than everything else except DA.

I said compact!

Many reasons,

• i dont need the stopping power
  
• dont want to spend the extra cash on somethin i dont need
  
• i got enve canti forks for less than the disc forks you got
  

last 2 reasons are purely economical so cant argue with that :P and mad enve jealousy (!)

But how do you know you dont need the stopping power? (genuine question btw)

If im using sram rival levers and a compact crankset whats the cheapest way to get a 12-32 compatible rear mech? The wifli mechs are pretty expensive

Assuming you have a short cage Rival mech .. This has a quoted chain wrap capacity of 33T. The difference at the front is 50-34 = 16 teeth. And 32-12 = 20 teeth. Giving a total requirement of 36 teeth. You do not have enough capacity ignoring the position of the mech in relation to the cassette - which is where the longer hanger that Dammit mentioned was used to space the mech away from the cassette. You may be able to squeeze a little extra capacity from the mech by changing the standard 11 tooth jockey wheels to Campagnolo or equivalent 10 tooth jockey wheels. But I'm not sure how much extra you'll get. You need wifli or a Sram 10speed mtb mech which has a nicer cable entry then road mechs to be sure if you want this low gearing.

This explains why I had so many problems with girls' undergarments in my youth.

You need to tuck it all underneath.

repped.

My housemate has a mtb with discs, ive tried and they stop fast an thats cool but ive never had problems stopping on calliper brakes and i rode to work in the snow, im not particularly heavy orfast and if pro CX riders can se then then i certainly can

Rep, cheers

@hippy .. yes speed reading I mised the word ergonomics .. and therefore I agree on your comment about 6700 being an ergonomic improvement over past Ultegra.

Disagree on the braking as Shimano mistake power for modulation and shifting performance that's subjective too .. but I'm not a Shimano fan boy

You can set-up cantis to work effectively as well as discs. You dont need any more power than locking a wheel. Modulation is more fiddly but doable.

The advantage is not having your braking dependant in the state of your rims.

As they do with disc brakes too.

They don't mistake anything for anything. Shimano brakes are the best. Pretty much every brake test conducted agrees with me.

As for fan boy, if there was something better, I'd be using it. I don't have shares in their company. I don't have Shimano stickers on my helmet.

DA road brakes set the standard.

Which is why mine were tested next to them, and found to be lighter, stiffer, more powerfaul, and have equal modulation.

Even beat shimano in the ugly stakes which is no mean feat.

Jus sayin....

Yeah, only in TRPs documentation.

I've not used them myself so will not call you a liar just yet :P

How much are they?

Eh? TRP stole the design from some bloke?

"Look. I'd had a lovely bike ride, and all I said to my wife was 'That groupset was good enough for Jehovah.'"

Fairwheel bikes latest brake shootout, DA 7900 is certainly in the top tier for power and modulation, but it's not on it's own.

Might be more interesting to find out who here is using a complete groupset, or just shifters/mechs the same, everything else from different suppliers, i.e. Campag SR shifters/mechs, Rotor cranks, TRP brakes etc.

Must spread rep...

I was convinced this would be impossible but I've never had any problem, can do it totally naturally. Maybe I just have long thumbs.

I have tiny hands. But this has never been an issue for me. I think thats down to lever position and bar shape. Campact bar + plus flat hood position, gives easy access to the lever from the drops.

I find it depends on where you hold the drops, you need to hold them right up in the curve to have access to the thumb shifter. But I do love how easy it is to shift more than 1 gear at a time.

My Sram Red brakes with the stock Swissstop pads and Gore Professional cables are fucking awesome. Tonnes of stopping power and tonnes of modulation. I find myself going down hills much faster than I used to because of the amount of confidence it gives me.

Would it be though, really?

I think it would be more interesting to go to the pub
