Sorry to but in...
...do those ^ drop outs mean that you don't have to worry about adjusting your brakes as the caliper moves as you effectively adjust the dropout/chain length?
Sliders do the same. But rockers mount the caliper out of the way of rack and mudguard struts.
I'm wondering if they limit the size of disc you can use though. I have a 160mm on my fat rear wheel. But I might one day fancey a 180mm. It kinda looks like the caliper will hit the seatstay if you go too big. Or maybe the angle keeps it within the rear triangle

Quick question,
I'm converting my tricross from SSCX to a kind of lightweight singlespeed 29er lowpro (V-brakes, fatter tyres, wide flat bars).What max size tyre would you recommend on an open pro rim? I'd like to think that I can go up to 2" but maybe it means too much side roll.
Will a tricross take 2" ?
That's what I'd wonder.
Do you reckon there's a clever way to sort out the brake reach for a 650B conversion? It would involve a new wheelset, but you'd want wider rims anyway.
-
Fork clearance is massive, the frame less so, 2" might be the limit, I don't mind having a slightly larger tyre at the front, in fact it would slacken the geometry a bit which will be a good thing as I did almost stack it on a few descents (right Dancingjames?)
I would have gone for halo aerowarriors but no breaking surface. Maybe I could rebuild the wheels with other rims, any thoughts on rims with the same ERD as openpros?
Maybe just some A119 or 319 -
I have used Bontrager XR 1.8 tyres on CXP33s with no rolling or anything else, so I would recommend ytou give your plan a go before worrying about new rims or wheels.
However, if you plan to use the lightweight singlespeed 29er lowpro for going off road then remember to leave mud clearance. Aluminium frames and fork crowns can get surprisingly damaged by gritty mud on too big tyres...

probably a question more suited for here:
final piece to the puzzle...
Clearance between the roller and the spokes is tight, but hey, it works. Do they do narrower rollers? Could I put spacers between the tensioner and the dropouts?
-
Hows it look from behind? ( chainline shot )
-
from this angle, I could move one spacer to the left of the cog, and the chainline would be bang on, but the chain would not sit in the roller.
As it's a 3/32" chain, I think I'll leave it like this. I rode round the block and it seems fine. Just wanted a more experienced opinion before I start thrashing it around.
-
as far as I can tell, no, unless you actually bend the tensioner arm or put some spacers between the dropout and the tensioner arm.
-
look like you need to removed one more link.
That look better than the crap tensioner I have on my MTB, need to order that one.
don't think I can! I was thinking about a 19t splined cog instead.
This tensioner is rad. no spring, easy to set up. no jockey wheel though, just a roller, so possibly more noisy.
So much better than the pricey and shite Surly Singleator I installed on Saturday and ended up getting a refund for. Kept spitting the chain out. And yes, it was installed correctly.
-
Looks like you have 3-4mm of thread protruding through the dropout, so a small washer between tensioner & dropout will be fine. Just be careful how much of the quick release skewer is held in the part above it.
-
That's a bloody enormous roller though. It looks more like a cotton reel :-)

almost all of it!
and the clearance is a little better...
might even go for thicker washers if I can find any, just to be sure.
cheers for help.
-
No worries. As long as that main bolt is fully engaged in the dropout, then get as much clearance as you can.
-
^ This, if it'll fit. Although you'll need the chainline to be reasonably good, a jockey wheel tends to run a bit quieter than a roller.
-
Good point. What about guards incase the chain jumps off?

I replace the rims if you want more than 32mm. OPs are nice to have in the parts box, or easily sold. Even a cheap wide rim will be better for your use. Seems a waste.
