M4 CX frame rear spacing?(8 posts)

M4 CX frame rear spacing?climbo

anyone know if it's 130 or 135mm? The complete bike is spec'd with a Hugi/S-Works hub which I thought was only made for MTN bikes so I am assuming it is 135mm right now. I was planning on using my old road wheels but maybe not now.

Hugi makes 130mm rear hubs. Most cross bikes are speced with 130mm rear hubs but you may want to check with a Specialized dealer just to be on the safe side. My hunch though is that it's a 130 spacing.

I hope it is but the BB they spec on the complete is a 118mm spindle which seems awfully wide for a 130mm rear spacing.

Interesting that they would spec an Ultegra triple BB, but most road bikes sold now have triple fronts with a 130mm road hub. I do recall when Specialized first released a S-Works CX bike and it was a lot of XTR. My guess is they downspeced to Ultegra to match a price point, not to mention XTR is overkill for cross racing. But realistically most cross bikes sold are never raced and you'll often see concessions for more versatility (rack mounts, triple BB spindles, etc).

As an aside, it looks like the new M4 frame has a seat tube cable pulley already.

and it is 135mm. Thanks to Guy's Bikes in PA, they are worth their salt !! Looks like I'll be needing a new wheel! aaaahh, the joys of building a bike yourself.

I would think twice about getting a cross frame with 135mm rear spacing. 700c wheels with 135mm hubs are extremely rare and you will not be able to swap wheels with anyone (ok, very, very few). If you are really serious about cross then you'll want to have a spare wheelset in the wheel pit which will require two sets of wheels that you can't use on anything other than the M4 frame.

I tend to switch frames/wheels/equipment a lot so I like stuff that minimizes compatibility issues. Worth considering at least...
I can swap with the teamclimbo

at least one other rider on my team will have the same frame and so we'll have spare wheels if needed. He has plenty of wheels and the bike store that sponsors the team will provide/build some extras if we need it. Last season I never had to change a wheel so hopefully I'll have the same luck this year. Plus, I got a great deal on the frame so I can't pass it up. I just can't wait to build this thing and ride it !!!!

130mm, I just measured it. Spacing is measured inside to inside of the dropouts.
