Hi there,
building up an r8 from scratch and have a few questions for you
1. What size seat clamp do I need?
2. What type of front mech do I need?
3. How many spacers to use on a HT 2 bottom bracket and which side do they go on?
Thanks in advance
Oranges FAQ sheet on their website will be your friend.
1. 29.8
2. 28.6, most Shimano mechs cover all cable pull variations
3. Spacers tend to go on the r/h side but will vary according to your preferred chainline
Cheers, 29.8? For a seat clamp? Can't seem to find any in that size
What do you mean "preferred chainline"

Here are the sizes of my R8 parts, (R8 Pro)
1) Seat clamp 30.0 mm
2) Top swing
3) I have 2 Spacers on the drive side and 1 on the non drive,Currently running an SLX tripe set.
Hope you get it up and running soon its an awsome bike im really happy i bought one, lovely ride. Hope this helps, any more info give us a shout.
Thanks, can't wait to get it built, probably be a few months yet,
so just to confirm seatpost is 27.2 and clamp is 30.0? And the front Mech clamps are multiple fit but it needs to be top swing?
Im using an SLX front mech at the minute, just the job!, Yes i have an orange stalk seat post at 27.2mm, the front mech should have shims with it to fit various sizes,i think with the seat clamp being 30mm you should need the 30mm shim.
28.6 front mech, two spacers drive, one non drive, 29.8 clamp, 27.2 seatpost.
Thanks, thats cleared it up but Any idea Who makes a 29.8 clamp?
google is your friend,
azonic do one
A clamp marked as 30.0mm will most likely be a 29.8mm rounded up.
Salsa make some of the best clamps on the market, they round up the size in this manner.
It'll have a 68mm BB shell which means your SLX chainset will need 2 spacers on the drive, and 1 on the non drive side.
And they use a topswing front mech to clear the bottle cage mounts on the seattube. The multifit mounts have 28.6, 31.8 and shimless run 34.9mm. So the 28.6 is the closest fit that'll work. IME you may need to use only 1 shim on the mech for a perfect fit.
look on crc
thomson do one aswell
So the 28.6 is the closest fit that'll workfront mech size is 28.6
Seat clamp has to be hope on an Orange HT. It's a by-law. 30mm is fine.
As stated, bottom pull techs will foul the bottle cage.
My thoughts entirely hope and orange = bread and butter
just brought one of these frames and the above is great help however iv a question.... im running an old square tappered xt chainset i know i need a 68mm bb however what lenght do i need?? there seem to be a few sizes ie. 110mm 113mm 122mm etc?? If anyone knows id be greatfull thanks - cant wait to get it built up!!
Running a 107mm on mine, however newer mechs may require a wider chainline before they'll shift down to granny, 110mm will probably do it fine.
Many thanks coatesty, so anyone know if I can still get sq tapper UN73 can only find 54 now??
Pretty much old stock only now, i'm one of those lucky souls with Royce BB's in my bikes, been faultless for years.
weel mine is now built and i can say for sure ill be using this more than my yeti 575 - r8 is an awesome ride i love it, infact cant keep of it!!!
