andreas17777 Posted February 22, 2022 Share Hi Everyone, I have a Trek Madone SLR 58 and went for another bike fit to sort out some issues. The situation is I need another 7mm on saddle height and the seat post is already on max. I can see my pedal efficiency has increase dramatically by just raising it by 3mm. I already have the longer seat post and currently on a 172.5 mm crank. I could ride a 175 crank but that's not ideal. Any innovative ideas on how to achieve this an extra 7mm of saddle height?

Bub Marley Posted February 22, 2022 Share Your frame is too small, mate. You’re gonna have to get a new one unfortunately. andreas17777 1 Link to comment Share on other sites More sharing options...
V18 Posted February 22, 2022 Share I had that under saddle u-bend spring for my hardtail commuter a while back. It gives about 35mm height . I didn't like it but the saddle clamp mechanism may be something to look into. andreas17777 1 Link to comment Share on other sites More sharing options...

Eldron Posted February 22, 2022 Share Chat to Graeme at Carbon Craft. He has worked some magic kon Trek seat masts for me. In unrelated news - are you short torso/long legs body type? andreas17777 1 Link to comment Share on other sites More sharing options...

And from the seat-post at max, had the same on the gravel bike and in October clean break of post and still struggling to recover after the fall with broken ribs and bruised kidneys. Wont take that risk ever again. Matthew du preez, andreas17777 and Sid the Sloth 2 1 Link to comment Share on other sites More sharing options...

Riders with short torsos/longer legs generally have to size up to get enough seat height then you have to compromise on stem length/handling. It is entirely possible that the frame is the right size. andreas17777 and NickGM 2 Link to comment Share on other sites More sharing options...

In unrelated news - are you short torso/long legs body type? Yes, thought about trying to get a carbon specialist to make the post longer, i'm 181 cm and 87 inseam. On trek's website it said 58 or a 60. Link to comment Share on other sites More sharing options...
Jewbacca Posted February 22, 2022 Share Make a longer seatpost. If you're handy, it's really easy to do yourself. Buy a 2nd matching seatpost, make a carbon sleeve join and then epoxy them together. That way the seatpost will extend well into the frame to eradicate any excess stress on the frame joins and give you more than enough seat post height. andreas17777 and _David_ 2 Link to comment Share on other sites More sharing options...

Probably cheaper than new cranks that would only yield 2.5mm anyway. andreas17777 1 Link to comment Share on other sites More sharing options...

Sid the Sloth Posted February 22, 2022 Share On a serious not, 7mm is really not that much... I wonder if you could get that by running a different saddle. In a bicycle industry with about 60 different bottom bracket standards and another millions seatpost styles, I find it tough to believe saddle to rail height is standardized... The ISM TT saddles are quite tall and could work, I found it super duper comfy. andreas17777 1 Link to comment Share on other sites More sharing options...

Is that not going to be a bit tricky with the aero seatpost? andreas17777 and Jewbacca 2 Link to comment Share on other sites More sharing options...
JA-Q001 Posted February 22, 2022 Share What seat and pedals are you using? You can win 5mm by using speedplay pedals. Some seats have a low Saddle to rail height, lke selle italia. Others are higher, like fizik, but only the normally padded ones. the differ up to 10 mm between something like a SI SLR and Fizik Areone. andreas17777 and Sid the Sloth 2 Link to comment Share on other sites More sharing options...

The ISM TT saddles are quite tall and could work, I found it super duper comfy. I'd love to get my hands on 185mm cranks as I'm tall and carry a lot of that length in my legs. I have the chest clearance when my forearms are parallel, and I have a silly high natural cadence so could really see benefits... Edit: Meant to quote your 177.5 post Edited February 22, 2022 by bleedToWin andreas17777 and Sid the Sloth 2 Link to comment Share on other sites More sharing options...
