While SRAM Rival 22 and Shimano 105 group sets are commonly considered to be at the same comparative level as far as performance, weight, cost and overall performance, that doesn't equate to their components potential to be successfully mixed. At least with an acceptable level of function. Whatever the system, it seems, mixing components from SRAM with ...

For BR-5700, BR-5800, and BR-R7000 they run off the various new school Shimano not-quite-short-pull cable travel numbers. SRAM road levers are all basically traditional short pull, which is less cable pull than Shimano Super SLR et al. The mismatch in this direction results in less pad movement but with more leverage than intended. It can typically be made ...

You will get brakes that work BUT won't be quite as the manufacturer intended because Shimano &SRAM use slightly different pull ratios. Campag and SRAM are supposedly the same, fyi. Does that answer your question?

I have no idae, but I just forgot to reinsert mine after cleaing my bb. My guess is that it keeps your bike frame clean from water that enters from outside via the hollow tech technology. Which mean water can enter the hole in your crank. I'm no bike expert, but I believe it does not effect the crank or bb functionally. So no you do not need it, but yes you ...

Might be shorter to list what you can keep: Frame and fork(probably, if the OLD spacing is the same) Front wheel Bars and stem Saddle and seatpost Pedals Brakes. You will need to buy or source replacement: Rear wheel hub because a freewheel and a cassette are too different. And its a sad truth that a whole-new wheel might be cheaper than a hub and ...

If your goal is to convert your 3 gears in the front and 7 gears in the back to a 3 in the front and 9 in the rear this will be quite expensive. A new rear wheel will be required Your current rear wheel uses a screw on freewheel to mount the rear gearset. Nine speed rear wheels use a freehub mounting system with a cassette. You will need a 9 speed rear ...

This is a partial answer. What else you will need: a rear shifter, your Shimano ST-EF41 will not be compatible with SRAM-X9 (as far as I know). On the other hand, SRAM and Shimano 9-spd cassette/chains should be interchangeable, so if you can (virtually) upgrade your Tourney 7-spd to something 9-spd Shimano, you should be able to then replace this something ...

Modern cranksets either have 24mm-ish width spindles, or 30mm-ish spindles. DUB (28.99mm spindle) falls into the latter category. GXP spindles (24mm, tapered to 22mm on one side) fall into the former. Almost all press fit bottom bracket shells can take cranks with 30mm or similar spindles. Trek’s BB90 bottom bracket standard appears to be an exception. That ...

The most common cause of this with XD cassettes is simple under-torquing of the "lockring"/locking sleeve/whatever you want to call it. SRAM's number is 40Nm. The sleeve turns with quite a bit of resistance inside the rest of the casssette on XD cassettes, which can lead to not having it actually tightened on right as the friction is eating up ...

Further research shows there are two systems, Matchmaker and Matchmaker X. My Guide T brakes allow the use of Matchmaker and the new Eagle Shifters use Matchmaker X. It seems as though all of the other Guide brakes (including the R the bottom picture above) use Matchmaker X. I either need to find a Matchmaker clamp adapter like this https://www.sram.com/en/...
