A bit of a twofer question...

I have a 2014 Specialized Epic WC who has seen a lot of miles. Right pedal is slightly loose and squeaking, LBS says it’s the “Sleeve” so they suggested replacing entire crankset. I’ve taken the pedal out and back in, I agree the issue is IN the crank where the threads are.

1) any ideas on mending the sleeve to which the pedals affix? It has a visible crack, and the pedal has 1-2mm play. Was thinking epoxy (dunno which type) but worried it wouldn’t work and I’d just have a pedal stuck in a broken crank.

2) If I do buy a replacement crank (he mentioned Truvativ Descendant), what all specs do I have to check out? So far just looking for BB30 and 175mm, but seems like there’s other variables I might need to consider.

Happy riding from Tucson

Aren't they just Shrader valves
don't think so, pretty sure they some tiny valve thing
Got a pic?

Hey guys, this is a 2019 Rockshox Deluxe RT3 w/ Thrushaft (Trek). Cross-threaded bolt pulled out the first 3-4 threads, so soft it just felt like pushing against locktite Frown

Questions are:

1) Can I safely tap this or would that put my frame at risk if it pulled out while riding?
2) Is it possible to replace the eyelets at the bottom of this shock, and if so, can it be done without replacing the whole damper body?

Thanks in advance!

You would have to replace the entire damper body. Just put a helicoil in there and send it.

Pretty sure you need this adapter - part code 5321530/C

Out of stock on CRC but I've seen a few on ebay and elsewhere.

Currently running a 1x9 w/ a sram x5 9 speed medium cage derailleur. Will an X-7 Type 2 10 speed rear derailleur work in place of the x5. Both look very similar, have 1:1 pull ration, just wondering if the extra speed would cause problems.

I need to get a snap ring out of my sram guide brake. I bought a pair of snap ring pliers at the local auto parts place, but they didn't have enough reach. I'm hoping someone here can recommend a brand of pliers that will work. Thanks.

Where is the snap ring in question?

Guessing you mean for master cylinder removal?

When I went to STU, we used a small pair of diagonal cutters instead of snapring pliers.

Thoughts on parks tool grease vs regular (canadian tire) grease?

Posted: Jul 14, 2019 at 10:43 Quote
Not to say that there all exactly the same but for general use CT grease won't do any harm as long as it isn't petroleum based like you'll find for automotive. Lithium based grease is good for bikes.

So I've just dinged another rim. EX511 with a ding that might not straighten out without cracking as its compressed/creased the side of the rim too. Was running 25psi with an exo casing dhr2 and I only weigh 75kg. Would I be better off switching to DD or similar or running an insert of some description?

Depends. Do you think the damage was a one off or your fault due to line choice, or simply because the trails you ride beat bikes? If the former, just ride better lines, if the latter, get inserts.
