can you advise which Hollowtech chainsets are compatible with 7 - 8 speed rear cassettes (Ultegra rear mech) please.

Perhaps I could buy a Hollowtech crankset separately from the rings ?

Answer: 
pretty much any chainset designed for a geared bike will run 7/8 speed set up as 7/8 speed chains are a wider chain, you would only have an issue with the chainrings "grabbing" if you used a 7/8 speed chainset with a narrow chain (9/10/11 speed)

Answer: 
There's no reason not to use the hollowtech chainsets with 7- or 8-speed casettes and chains. The chainrings will be slightly narrower than necessary, as they're designed for either 9- or 10-speed chains, but it won't actually cause you any problems. Of course, you could mount 7- or 8-speed chainrings on the cranks, assuming the BCD (bolt-circle-diameter) is the same, but there wouldn't really be any advantage to doing so.

Answer: 
the problem of compatibility arises only for cassette 9, 10 and 11 speeds, because the chains are thinner and would not go on the front chainrings. your chain that is wider enters on all the front chainrings. Thinner ones must be more resistant, with use of better alloys, therefore more expensive. you do the math! ...

Quastion about Brakes Formula R1S

I have a quastion about brakes Formula R1S - which calipers they have?

I read one comment about them, man said taht they have RX calipers..
(The picture and description shows an R1 lever and caliper, however the caliper I received is Rx. These are OEM brakes and do not have the line shortening hardware that the normal retail product includes. This is not a good price on these brakes considering you need to buy two line shortening kits and the calipers are Rx.)

http://www.chainreactioncycles.com/ua/ru/formula-r1s-disc-brake-set-2012/rp-prod93694

Is it true or false? I will buy them if they all R1S))
Thanks for answer

Answer: 
RX calliper and R1 levers. You get the lever feel and function of the R1's and the excellent calliper of the RX, think of it as an upgraded RX or a hybrid brake.

ЭНДОТЕРМИЧЕСКИЙ кронциркуль и рычаги R1. Вы получаете чувство рычага и функцию R1's и превосходного кронциркуля ЭНДОТЕРМИЧЕСКОГО, думаете об этом как модернизированное ЭНДОТЕРМИЧЕСКОЕ или гибридный тормоз.

Answer: 
There is no such thing as R1S calipers.

R1S Brakes consist of R1 design levers and RX design calipers.

So effectively R1S Brakes is a mix between R1 and RX.

Answer: 
Just forget about the below if you've already solved the matter.

It's the disk brake that decides which adaptor to use, not the fork.
Check the brand and model No of the brake first and look for the
right adaptor. It should indicate on the catalogue or whatever like
"160mm-180mm adaptor". You can probably find one on CRC site.

Make sure to choose the Post-Mount type, which is the standard
of Manitou, not the international type. Never use the adaptor of the
different brand, as it's too risky and very dangerous.

I've once done the same conversion with a Manitou fork & Avid BB7.
I got the right adaptor from CRC and it worked perfectly.

Good luck.
