Paging atpjunkie (and anyone else) re: Paul's ThumbiesThe Walrus

I've had the Thumbies for a week, but just installed 'em last night, after getting some other projects wrapped up. First impressions...nicely machined and finished. Really,
i really
should have a hinged clamp--there's no excuse for having to unwrap the bar and remove everything just to slip these mounts on, and then replace everything and re-wrap, especially for $50 (soon to be $55) a set. Otherwise, the actual installation and assembly is very simple.
Busy, busy, busy...The Walrus

Depending on the bar you're running, the shifters can wind up
i very
close. The clamps would require shimming to go anywhere but on the bulge, so this can be limiting if the bulge on your bar is not very wide. The crossing of the cable housings in front of the stem looks worse than it is, and doesn't pose any functional problem. By the time you add these to a set of top-mount brake levers, though, it's pretty busy up there. Adding a set of headlights could be problematic; even a computer might not fit in there.

I can't give a road test yet, since I've only tooled up and down the street checking the shifting and general positioning. It felt pretty good, and after I wrap the bar, I hope to give it a good workout this weekend.

A caution to anyone installing these--you'll probably need to swap the cable routing for the derailleur cables, what with the shifters being so close to the stem.
Rear derailleur questionarctic hawk

Which derailleur are you hooking up to on the back end? I am asking this question as I see that you are using bar con shifters (mounted up on the bar, hmm....).
I was thinking of swapping out the short cage Ultegra for a long cage XT so I can run 11-34 in back & 53/39 up front & hopefully get the best of both worlds.
Yup! Still having a personal gearing debate!

A-Hawk!
Bar cons work fine with XT.KG 361

I'm using a barcon to shift an XT long cage, 11-34 cog. Easy to set up and no problems.
9sp XT...The Walrus
Jan 15, 2004 12:14 PM
...but the bar cons will work with any 9sp Shimano mech. With the Paul's mounts, you could also run 8sp bar cons (and the appropriate cassette), or even a 7sp cassette and derailleur if you use the limit screws to block out the "extra" position.
8spd bar con????arctic hawk
Jan 15, 2004 1:46 PM
I am using the following bar con, SL-BS64, & an 8spd cassette. How can I tell if it is an 8spd bar con?

8spd bar con????atpjunkie
Jan 15, 2004 3:09 PM
I'll check mine when I get home, will try to post tomorrow but most likely later. As they are now D/A bar cons are 9 speed and Ultegras are 8/9. Have a 8speed set up and a nine.
If all else fails, count the clicks...The Walrus
Jan 15, 2004 5:51 PM
...you'd get 7 on an 8sp and 8 on a 9sp. Besides, the shifting would be not-quite-right if you were using a 9sp bar con with an 8sp cassette.

...and I just went and looked at what I know to be an 8sp Ultegra unit, and it is, indeed, an SL-BS64.
XT RD questionarctic hawk
Jan 16, 2004 7:47 AM
Say if I am running an 8spd bar con shifter, can I use a 9sp XT RD?

A-Hawk
XT RD questionKG 361
Jan 16, 2004 9:17 AM
Don't think so. You would run out of "clicks". You could do the opposite-use an 8 speed rear with 9 speed barcon, but not the other way around.
XT RD questionatpjunkie
Jan 16, 2004 9:53 AM
if you have 8 speed bar cons, find a 97 or 98 era XT rear der. (preferrably short cage). these are the most reliable der. shimano ever built (maybe a close tie with 1st gen. silver XTR) and an 11-30 or 11-29 XT cassette. IMHO this is the way to go for cx.
Yes, the derailleur doesn't care what kind of shifter it is...The Walrus
Jan 16, 2004 1:24 PM
...the indexing is in the shifter, and the derailleur just does what it's told. I've run 9sp mechs with 7, 8 and 9sp shifters without adverse results.
Yes. nmMShaw

Question-KG 361
Jan 15, 2004 8:54 AM
Does the kit just include the mounts? I'm interested in them but I'm using a 1x9 so I only need 1 and I'm not paying $50 for 2 if I don't need to! I have a slightly more demented way of top-mounting the bar con. Works fine but it could have it's "issues".
Yep, it's just the mounts...The Walrus
Jan 15, 2004 12:29 PM
...(and the sticker set). I can see how someone would have some real questions about the price (I know I do...), but I guess I've gotta factor in the "Geez, that's weird/cool" element, plus the fact that this setup really does address a need (for me, at least).

Saw the pics of your, ummmm, "novel" installation earlier--safety issues aside, it's actually a damned clever approach, although I just thought of something else that might work. Supergo sells this accessory stem cap set that has a bar for mounting stuff like computers, lights, etc. You could probably drill through this thing, and run a bolt through it to clamp on the bar con. I think I'm gonna go study this right now...

It'd be nice if some Taiwanese outfit like Tektro would be interested sufficiently to make cheap knockoffs of the Paul's mounts.
so they fit on the 'bulge'.atpjunkie
Jan 15, 2004 1:17 PM
if so too bad. I was thinking of instead of a top mount with all that bulk (and no room for lights...etc..) trying to mount in the flat part of the bend 'a la Take Offs' so I could shift from the drops.

Jan 15, 2004 1:21 PM
it amazes me the extent we go to because of the inherent problems with STI. I wish a Shimano rep or tech was viewing our posts, then again maybe they are and just don't give a @#$%!

Jan 15, 2004 2:52 PM
what problems have you had with STI for cross? i haven't tried them (am building up a cross bike soon) and am curious to hear about your negative experiences.
STIatpjunkie
Jan 15, 2004 3:19 PM
check posts from the past but in summation, right lever tends to die and stick (will happen on road as well at about 10K miles, Ult. STI) but is sped up with the gunk and grit of cx. .02 cent return spring dies so you are able to shift up back cassette but not back down. Shimano has a repair by replace policy so to fix a 2 cent spring will cost you about $179 or a search to find a Rt Only STI. look on ebay and notice how many Left Ult. STI's are for sale. It's from cyclists replacing in the aforementioned style and attempting to recoup their losses. One crash in a muddy and/or sandy pit can destroy a new or near new shifter. Campy Ergos can be rebuilt and actually field serviced. Shimano Factory techs won't dare to open an STI. Bar Ends are cheap, reliable, can be shifted with heavy gloves, andwill survive all kinds of abuse on which is why you still see them in cross. Cross is also (at least up until lately) the sport where guys tended to build beaters and not waste $$$ on their rigs (better served on the roadie) so bar ends were the economical choice. If you have money to burn by all means go ahead...actually on second thought if you have money to burn go Campy, it just makes better sense (cents). This mainly applies to wetter areas, if you live in a drier area it isn't as much of an issue.

IMHO the benefits of brifters outweigh their liabilities. I've been riding my 'cross bike as a mtn bike for the last few months because a friend has been borrowing my mtn bike. Having the shifting RIGHT THERE is a good thing.

Ole ATPJunkie's right if you live where it gets really wet/muddy/cold because then barcons really shine.

That said, if you look around you can usually find almost anything you want for dirt cheap... Buy it before you really need it. My last pair of Ultegra STI were shop takeoffs that I got for $49...

If you have the $$, I'd go 9sp Ergo shifters and a lower-end rear derailleur with Shimano everything else.

That help?

that certainly does help (both responses). after searching the forum archives for feedback on 10 speed campy for cross, i've more or less decided to go with that for my build. a couple reasons: 1) i have 10 speed road wheels that i'd like to use on the cross bike (my "commuter" wheels), 2) i'd like to be able to swap cassettes between my road and "cross" bike because 3) i plan on riding the "cross" bike a lot on mixed road/trail rides and in bad weather (thus the quotes around cross as it's not a pure cross bike i guess).

I bookmarked positive responses from a handful of folks here about 10 speed campy for cross. the frame is still being built though and the components haven't been purchased. a big motivator is the ability to use my existing wheels and cassettes with this bike (big money saver). i'm still open to feedback on the 9 vs. 10 speed campy question.
I'd be inclined to agree with the last part of your rant...The Walrus
Jan 15, 2004 5:46 PM
...but, as we all are aware, Shimano Knows Best.
I've never actually tried Take Offs...The Walrus
Jan 15, 2004 5:59 PM
...but you should be able to slap a set off bar cons on them instead of the downtube shifters, right? I'm thinking both kinds of shifters mount on the same kind of boss...or is there some kind of positioning issue with the Take Offs?
You can see why I'm interested in alternatives =)KG 361
Jan 15, 2004 6:29 PM
Actually, when riding it, the shifter isn't aimed at any "vital" areas =) Besides, it isn't sharp and I've never even come close to coming down on the stem (having said that, I will likely do it next time out....)

No offense, but these are MOUNTAIN bike parts. That they've been adapted for road bars is a nice gesture on Paul's part. I'd bet that there's a REALLY small market for these things. That they made them at all is a miracle!

I've got a pair that I need to install myself, but these are going on my mtn bike. It'll be an upgrade from an XT 6sp shifting friction right now...

Mike
I agree--it's great that Paul listened to our requests, but...The Walrus

...I am just pointing out a few aspects of the mounts that might make them unsuitable/undesirable for some prospective users; after all, this

Incidentally, I got to go for a longer (~15 mi.) ride yesterday (all pavement, unfortunately), and I liked the setup more and more. They might not be for everyone, but whatever reservations I had about them are quickly disappearing, now that I have them installed and tweaked.

He is going to sell me just 1 since I run a 1x9. Most large companies wouldn't do that. It's nice to know that there are "little guys" out there that will cater to their customer's needs.

Wish I'd known that. I'm keeping the left thumbie XT 'cause it still works. Its not matching, but hey, I ride road/track more than I ride mtn so I don't really give a hoot.

We went out for a spin around PQ in San Diego again last night. Everything was going well till we got almost to the top of Telephone Poles when Mike's XTR derailleur committed hari-kari in his spokes. He single-speeded his bike to get him back to the house. A few pushes up the big hills later, we all got back safe and sound except for the XTR derailleur that is.

Anyway, back to the thumbies.

They rock! It isn't QUITE the same as a thumb shifter, but it still feels good. Amazingly, the barcons feel almost like they were made to do what they're doing on the thumbies mount.

If you're waffling, BUT SOME!

Ordered them last week (ok, ordered IT). Can't wait to get it. I've bben riding the 'cross on my roadbike trips since it hasn't been over 25F is the past week or so...Nice to have the security of those speedmaxes over the occassional snow-covered section, plus it keeps the speed down a bit =)
