From their blog, it is clear that SRM have a few new FSA PMs coming out next year. I'd be interested in details of these, particularly in relation to the ease of changing between bikes.

I will have one team bike with Campy, and another training bike and TT bike with Shimano next year, and would like to get an SRM that fits with both. I've read that people have had issues with FSA cranksets in the past, but it may be that the new systems have dealt with said issues?

Before anyone says, 'Get the DA version', I would prefer to avoid the aesthetic conflict of a bike with a Campy groupset and DA chainset. Call me a prima donna and I'll agree :?

I think I have pictures of those from Interbike actually. Don't think any version - except the wireless - is going to be easier to move to a different bike.

1) you won't know if the past issues with FSA SRM's have been resolved (or if there are new issues) until people have been using these for a while.

2) wireless SRMs do not appear to be 100% sorted yet. There is a firmware update in the works, but I would not advise anybody to go wireless at this time.

3) wired SRMs are just as easy to move from one bike to the other, you just need a wiring harness on each bike.

4) This new FSA SRM appears to be heavier than the standard Professional SRM - which costs $800 less.

Not true for those moving from MegaExo to frameset with press-fit bottom bracket standard.

1) I've been using my wireless FSA SRM for a while now and have had no issues.
2) See #1. No issues at all. It's paired to a Garmin 705.
3) Can't comment.
4) Can't comment.

What makes you say the FSA K-Force Light version appears to be heavier than the SRM Professional version?

Claimed weight from SRM:
SRM FSA K-Force Light: 908 gram including BB
SRM Professional: 827 gram excluding BB.

908 g - 827 g = 81 g

So you need to find a square taper BB lighter than 88 g to make the SRM Professional setup lighter than the SRM FSA setup. I'm not aware of any square taper BB that light.

A Token square taper BB with Titanium axle has a claimed weight of 155 g.

827 g + 155 g = 982 g



It does however seem a bit stange the K-Force light is claimed to be that heavy, because the old SRM FSA version has a claimed weight of only 786 g: http://www.srm.de/englisch/prod_srmts_str_fsa.html
But maybe the wireless technology and liklkely larger battery makes it that much heavier. But then with the wireless version you also save the weight of the wiring harness.

Really? That would be their cheapest by $500.

So is the gossamer going to be 2500 retail for complete with Powercontrol? Also will it be wired or wireless for this price? Thanks.

Not an answer, and someone will surely correct me if this is incorrect but I was under the impression that once the wireless PM cranksets were introduced, SRM were no longer going to produce wired versions.
